DO NOT remove this board or cut the cable between the compensation board and load cell. Removal of this board voids the calibration and warranty of the load cell.GeneralThe OMEGA®LCKD Series subminiature compression load cells arecompression-only units that are highly cost-effective. To ensureexcellent long-term stability and reliability in severe environments, theLCKD Series utilize high quality strain gages, precision gagingtechniques and all stainless steel construction. These units have a loadbutton machined as an integral part of the basic load cell. The load cellis designed to operate by mounting on a flat surface. The LCKD mustrest on a flat surface the same diameter as the D1dimension for properoperation.Shunt CalibrationThe LCKD Series are highly accurate millivolt output type load cellswith shunt calibrator for quick calibration checks. Shunt calibrationallows the user to install and calibrate the instrument in the fieldwithout the use of a dead weight tester. A 59 kilohm resistor is shortedacross negative excitation and negative signal output at the factory,which produces a simulated millivolt signal out of the transducer. Theshunt calibration signal is equivalent to a simulated pressure of:Shunt Cal mV/VSimulated Load = x Full Scale LoadCalibration Factor mV/VExample: Model LCKDWhere:Calibration Factor - 2.0315 mV/VShunt Cal - 1.4962 mV/VSimulated Load = 1.4962x 50 = 36.852.0315To set up the transducer in the field, follow these steps:1. Connect transducer excitation terminals to dc power supply.2. Connect transducer signal output terminals to readout instrument(DVM, Analog meter, etc.)3. Turn power on.4. Null transducer signal output with zero adjust potentiometer on meter.5. Short a 59 kilohm resistor across negative excitation and negativesignal output.6. Adjust the span potentiometer until the readout instrument reads thesimulated load as computed above (or that percent of full scalepressure).7. Remove 59 kilohm resistor and repeat steps 4 to 6 if necessary.(Span and Zero adjust pots may interact).8. The meter is now calibrated.IMPORTANT:Every load cell comes with a calibration sheet stating its full scale output, and this manual.

General DescriptionThe MAX3440E–MAX3444E fault-protected RS-485 and J1708 transceivers feature ±60V protection from signal faults on communication bus lines. Each device contains one differential line driver with three-state output and one differential line receiver with three-state input. The 1/4-unit-load receiver input impedance allows up to 128 trans-ceivers on a single bus. The devices operate from a 5V supply at data rates of up to 10Mbps. True fail-safe inputs guarantee a logic-high receiver output when the receiver inputs are open, shorted, or connected to an idle data line.Hot-swap circuitry eliminates false transitions on the data bus during circuit initialization or connection to a live backplane. Short-circuit current-limiting and ther-mal shutdown circuitry protect the driver against exces-sive power dissipation, and on-chip ±15kV ESD protection eliminates costly external protection devices.The MAX3440E–MAX3444E are available in 8-pin SO and PDIP packages and are specified over industrial and automotive temperature ranges.ApplicationsRS-422/RS-485 Communications Truck and Trailer Applications Industrial NetworksTelecommunications Systems Automotive Applications Featureso ±15kV ESD Protection o ±60V Fault Protectiono Guaranteed 10Mbps Data Rate (MAX3441E/MAX3443E)o Hot Swappable for Telecom Applications o True Fail-Safe Receiver Inputso Enhanced Slew-Rate-Limiting Facilitates Error-Free Data Transmission(MAX3440E/MAX3442E/MAX3444E)o Allow Up to 128 Transceivers on the Bus o -7V to +12V Common-Mode Input Rangeo Automotive Temperature Range (-40°C to +125°C)o Industry-Standard PinoutMAX3440E–MAX3444E±15kV ESD-Protected, ±60V Fault-Protected,10Mbps, Fail-Safe RS-485/J1708 Transceivers________________________________________________________________Maxim Integrated Products 1Pin Configurations and Typical Operating CircuitsOrdering Information19-2666; Rev 0; 10/02For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .Ordering Information continued at end of data sheet.M A X 3440E –M A X 3444E±15kV ESD-Protected, ±60V Fault-Protected,10Mbps, Fail-Safe RS-485/J1708 Transceivers 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

These devices feature fail-safe circuitry, which guarantees a logic-high receiver output when the receiver inputs are open or shorted, or when they are connected to a terminated transmission line with all drivers disabled (see the True Fail-Safe section). All devices have a hot-swap input structure that prevents disturbances on the differential signal lines when a circuit board is plugged into a hot back-plane (see the Hot-Swap Capability section). The MAX3440E/MAX3442E/MAX3444E feature a reduced slew-rate driver that minimizes EMI and reduces reflec-tions caused by improperly terminated cables, allowing error-free data transmission up to 250kbps (see the Reduced EMI and Reflections section). The MAX3441E/MAX3443E drivers are not slew-rate limited, allowing transmit speeds up to 10Mbps.DriverThe driver accepts a single-ended, logic-level input (DI) and transfers it to a differential, RS-485/RS-422level output (A and B). Deasserting the driver enable places the driver outputs (A and B) into a high-imped-ance state.ReceiverThe receiver accepts a differential, RS-485/RS-422level input (A and B), and transfers it to a single-ended,logic-level output (RO). Deasserting the receiver enable places the receiver inputs (A and B) into a high-imped-ance state (see Tables 1–7).Low-Power Shutdown(MAX3442E/MAX3443E/MAX3444E)The MAX3442E/MAX3443E/MAX3444E offer a low-power shutdown mode. Force DE low and RE high to shut down the MAX3442E/MAX3443E. Force DE and RE high to shut down the MAX3444E. A time delay of 50ns prevents the device from accidentally entering shutdown due to logic skews when switching between transmit and receive modes. Holding DE low and RE high for at least 800ns guarantees that the MAX3442E/MAX3443E enter shutdown. In shutdown, the devices consume a maxi-mum 20µA supply current.±60V Fault ProtectionThe driver outputs/receiver inputs of RS-485 devices in industrial network applications often experience voltage faults resulting from shorts to the power grid that exceed the -7V to +12V range specified in the EIA/TIA-485 standard. In these applications, ordinary RS-485devices (typical absolute maximum -8V to +12.5V)require costly external protection devices. To reduce system complexity and eliminate this need for external protection, the driver outputs/receiver inputs of the MAX3440E –MAX3444E withstand voltage faults up to ±60V with respect to ground without damage.Protection is guaranteed regardless whether the device is active, shut down, or without power.True Fail-SafeThe MAX3440E –MAX3444E use a -50mV to -200mV differential input threshold to ensure true fail-safe receiver inputs. This threshold guarantees the receiver outputs a logic high for shorted, open, or idle data lines. The -50mV to -200mV threshold complies with the ±200mV threshold EIA/TIA-485 standard.M A X 3440E –M A X 3444E±15kV ESD-Protected, ±60V Fault-Protected,10Mbps, Fail-Safe RS-485/J1708 Transceivers 12______________________________________________________________________________________±15kV ESD ProtectionAs with all Maxim devices, ESD-protection structures are incorporated on all pins to protect against ESD encountered during handling and assembly. The MAX3440E –MAX3444E receiver inputs/driver outputs (A, B) have extra protection against static electricity found in normal operation. Maxim ’s engineers have developed state-of-the-art structures to protect these pins against ±15kV ESD without damage. After an ESD event, the MAX3440E –MAX3444E continue working without latchup.ESD protection can be tested in several ways. The receiver inputs are characterized for protection to ±15kV using the Human Body Model.ESD Test ConditionsESD performance depends on a number of conditions.Contact Maxim for a reliability report that documents test setup, methodology, and results.Human Body ModelFigure 9a shows the Human Body Model, and Figure 9b shows the current waveform it generates when dis-charged into a low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of inter-est, which is then discharged into the device through a 1.5k Ωresistor.Driver Output ProtectionTwo mechanisms prevent excessive output current and power dissipation caused by faults or bus contention.The first, a foldback current limit on the driver output stage, provides immediate protection against short cir-cuits over the whole common-mode voltage range. The second, a thermal shutdown circuit, forces the driver out-puts into a high-impedance state if the die temperature exceeds +160°C. Normal operation resumes when the die temperature cools to +140°C, resulting in a pulsed output during continuous short-circuit conditions.MAX3440E–MAX3444E±15kV ESD-Protected, ±60V Fault-Protected,10Mbps, Fail-Safe RS-485/J1708 Transceivers______________________________________________________________________________________13Figure 9a. Human Body ESD Test ModelM A X 3440E –M A X 3444E±15kV ESD-Protected, ±60V Fault-Protected,10Mbps, Fail-Safe RS-485/J1708 Transceivers 14______________________________________________________________________________________Hot-Swap CapabilityHot-Swap InputsInserting circuit boards into a hot, or powered, back-plane may cause voltage transients on DE, DE/RE, RE ,and receiver inputs A and B that can lead to data errors.For example, upon initial circuit board insertion, the processor undergoes a power-up sequence. During this period, the high-impedance state of the output drivers makes them unable to drive the MAX3440E –MAX3444E enable inputs to a defined logic level. Meanwhile, leak-age currents of up to 10µA from the high-impedance out-put, or capacitively coupled noise from V CC or G ND,could cause an input to drift to an incorrect logic state.To prevent such a condition from occurring, the MAX3440E –MAX3443E feature hot-swap input circuitry on DE, DE/RE, and RE to guard against unwanted dri-ver activation during hot-swap situations. The MAX3444E has hot-swap input circuitry only on RE .When V CC rises, an internal pulldown (or pullup for RE )circuit holds DE low for at least 10µs, and until the cur-rent into DE exceeds 200µA. After the initial power-up sequence, the pulldown circuit becomes transparent,resetting the hot-swap tolerable input.Hot-Swap Input CircuitryAt the driver-enable input (DE), there are two NMOS devices, M1 and M2 (Figure 10). When V CC ramps from zero, an internal 15µs timer turns on M2 and sets the SR latch, which also turns on M1. Transistors M2, a 2mA current sink, and M1, a 100µA current sink, pull DE to GND through a 5.6k Ωresistor. M2 pulls DE to the disabled state against an external parasitic capaci-tance up to 100pF that may drive DE high. After 15µs,the timer deactivates M2 while M1 remains on, holding DE low against three-state leakage currents that may drive DE high. M1 remains on until an external current source overcomes the required input current. At this time, the SR latch resets M1 and turns off. When M1turns off, DE reverts to a standard, high-impedance CMOS input. Whenever V CC drops below 1V, the input is reset.A complementary circuit for RE uses two PMOS devices to pull RE to V CC .__________Applications Information128 Transceivers on the BusThe MAX3440E –MAX3444E transceivers 1/4-unit-load receiver input impedance (48k Ω) allows up to 128transceivers connected in parallel on one communica-tion line. Connect any combination of these devices,and/or other RS-485 devices, for a maximum of 32-unit loads to the line.Reduced EMI and ReflectionsThe MAX3440E/MAX3442E/MAX3444E are slew-rate limited, minimizing EMI and reducing reflections caused by improperly terminated cables. Figure 11shows the driver output waveform and its Fourier analy-sis of a 125kHz signal transmitted by a MAX3443E.High-frequency harmonic components with large ampli-tudes are evident.Figure 12 shows the same signal displayed for a MAX3442E transmitting under the same conditions.Figure 12’s high-frequency harmonic components are much lower in amplitude, compared with Figure 11’s,and the potential for EMI is significantly reduced.Figure 10. Simplified Structure of the Driver Enable Pin (DE)In general, a transmitter ’s rise time relates directly to the length of an unterminated stub, which can be dri-ven with only minor waveform reflections. The following equation expresses this relationship conservatively:Length = t RISE / (10 x 1.5ns/ft)where t RISE is the transmitter ’s rise time.For example, the MAX3442E ’s rise time is typically 800ns, which results in excellent waveforms with a stub length up to 53ft. A system can work well with longer unterminated stubs, even with severe reflections, if the waveform settles out before the UART samples them.RS-485 ApplicationsThe MAX3440E –MAX3443E transceivers provide bidi-rectional data communications on multipoint bus trans-mission lines. Figures 13 and 14show a typical network applications circuit. The RS-485 standard covers line lengths up to 4000ft. To minimize reflections and reduce data errors, terminate the signal line at both ends in its characteristic impedance, and keep stub lengths off the main line as short as possible.J1708 ApplicationsThe MAX3444E is designed for J1708 applications. To configure the MAX3444E, connect DE and RE to G ND.Connect the signal to be transmitted to TXD. Terminate the bus with the load circuit as shown in Figure 15. The drivers used by SAE J1708 are used in a dominant-mode application. DE is active low; a high input on DE places the outputs in high impedance. When the driver is disabled (TXD high or DE high), the bus is pulled high by external bias resistors R1 and R2. Therefore, a logic level high is encoded as recessive. When all transceivers are idle in this configuration, all receivers output logic high because of the pullup resistor on A and pulldown resistor on B. R1 and R2 provide the bias for the recessive state.C1 and C2 combine to form a 6MHz lowpass filter, effec-tive for reducing FM interference. R2, C1, R4, and C2combine to form a 1.6MHz lowpass filter, effective for reducing AM interference. Because the bus is untermi-nated, at high frequencies, R3 and R4 perform a pseudotermination. This makes the implementation more flexible, as no specific termination nodes are required at the ends of the bus.MAX3440E–MAX3444E±15kV ESD-Protected, ±60V Fault-Protected,10Mbps, Fail-Safe RS-485/J1708 Transceivers______________________________________________________________________________________155.00MHz 500kHz/div 020dB/div 2V/div Figure 11.

may affect device reliability.VCC GND WP SCL SDA1.Pin DescriptionSERIAL CLOCK(SCL):The SCL input is used to positive edge clock data into each EEPROM device andnegative edge clock data out of each device.SERIAL DATA(SDA):The SDA pin is bidirectional for serial data transfer.This pin is open-drain driven and may be wire-ORed with any number of other open-drain or open-collector devices.DEVICE/PAGE ADDRESSES:The Atmel®ATMLH444does not use the device address pins,which limits the number of devices on a single bus to one.WRITE PROTECT(WP):The ATMLH444has a write protect pin that provides hardware data protection.The write protect pin allows normal read/write operations when connected to ground(GND).When the write protect pin is connected to V CC,the write protection feature is enabled and operates as shown in<blue>Table1-1.Table1-1.Write Protect2.Memory OrganizationAtmel ATMLH444,16K SERIAL EEPROM:Internally organized with 128pages of 16-bytes each,the 16K requires an 11-bit data word address for random word addressing.Table 2-1.Pin Capacitance (1)Note:1.This parameter is characterized and is not 100%testedTable 2-2.DC CharacteristicsNote:1.V IL min and

pulse voltages:0.3V CC to0.7V CCInput rise and fall times:≤50nsInput and output timing reference voltages:0.5V CC3.Device OperationCLOCK and DATA TRANSITIONS:The SDA pin is normally pulled high with an external device.Data on the SDA pin may change only during SCL low time periods(see<blue>Figure3-4on page7).Data changes during SCL high periods will indicate a start or stop condition as defined below.START CONDITION:A high-to-low transition of SDA with SCL high is a start condition which must precede any other command(see<blue>Figure3-5on page8).STOP CONDITION:A low-to-high transition of SDA with SCL high is a stop condition.After a read sequence,the stop command will place the EEPROM in a standby power mode(see<blue>Figure3-5on page8).ACKNOWLEDGE:All addresses and data words are serially transmitted to and from the EEPROM in8-bit words.The EEPROM sends a zero to acknowledge that it has received each word.This happens during the ninth clock cycle.STANDBY MODE:The Atmel®ATMLH444features a low-power standby mode which is enabled:(a)upon power-up and(b)after the receipt of the STOP bit and the completion of any internal operations.2-WIRE SOFTWARE RESET:After an interruption in protocol,power loss or system reset,any2-wire part can be protocol reset by following these steps:1.Create a start bit condition2.Clock nine cycles3.Create another start bit followed by stop bit

requires an8-bit device address word following a start condition to enable the chip for a read or write operation(refer to<blue>Figure6-1).The device address word consists of a mandatory one,zero sequence for the first four most significant bits as shown.This is common to all the EEPROM devices.The next three bits used for memory page addressing and are the most significant bits of the data word address which follows.The eighth bit of the device address is the read/write operation select bit.A read operation is initiated if this bit is high and a write operation is initiated if this bit is low.Upon a compare of the device address,the EEPROM will output a zero.If a compare is not made,the chip will return to a standby state.5.Write OperationsBYTE WRITE:A write operation requires an8-bit data word address following the device address word andacknowledgment.Upon receipt of this address,the EEPROM will again respond with a zero and then clock in the first8-bit data word.Following receipt of the8-bit data word,the EEPROM will output a zero and the addressing device,such as a microcontroller,must terminate the write sequence with a stop condition.At this time theEEPROM enters an internally timed write cycle,t WR,to the nonvolatile memory.All inputs are disabled during this write cycle and the EEPROM will not respond until the write is complete(see<blue>Figure6-2on page10).PAGE WRITE:The16K EEPROM is capable of an16-byte page write.A page write is initiated the same as a byte write,but the microcontroller does not send a stop condition after thefirst data word is clocked in.Instead,after the EEPROM acknowledges receipt of the first data word,themicrocontroller can transmit up to fifteen data words.The EEPROM will respond with a zero after each data word received.The microcontroller must terminate the page write sequence with a stop condition(see<blue>Figure6-3 on page11).The data word address lower four bits are internally incremented following the receipt of each data word.Thehigher data word address bits are not incremented,retaining the memory page row location.When the wordaddress,internally generated,reaches the page boundary,the following byte is placed at the beginning of thesame page.If more than sixteen data words are transmitted to the EEPROM,the data word address will“roll over”and previous data will be overwritten.ACKNOWLEDGE POLLING:Once the internally timed write cycle has started and the EEPROM inputs aredisabled,acknowledge polling can be initiated.This involves sending a start condition followed by the deviceaddress word.The read/write bit is representative of the operation desired.Only if the internal write cycle hascompleted will the EEPROM respond with a zero allowing the read or write sequence to continue.6.Read OperationsRead operations are initiated the same way as write operations with the exception that the read/write select bit in the device address word is set to one.There are three read operations:current address read,random address read and sequential read.CURRENT ADDRESS READ:The internal data word address counter maintains the last address accessed during the last read or write operation,incremented by one.This address stays valid between operations as long as the chip power is maintained.The address “roll over”during read is from the last byte of the last memory page to the first byte of the first page.The address “roll over”during write is from the last byte of the current page to the first byte of the same page.Once the device address with the read/write select bit set to one is clocked in and acknowledged by the EEPROM,the current address data word is serially clocked out.The microcontroller does not respond with an input zero but does generate a following stop condition (see <blue>Figure 6-4on page 11).RANDOM READ:A random read requires a “dummy”byte write sequence to load in the data word address.Once the device address word and data word address are clocked in and acknowledged by the EEPROM,themicrocontroller must generate another start condition.The microcontroller now initiates a current address read by sending a device address with the read/write select bit high.The EEPROM acknowledges the device address and serially clocks out the data word.The microcontroller does not respond with a zero but does generate a following stop condition (see <blue>Figure 6-5on page 11).SEQUENTIAL READ:Sequential reads are initiated by either a current address read or a random address read.After the microcontroller receives a data word,it responds with an acknowledge.As long as the EEPROM receives an acknowledge,it will continue to increment the data word address and serially clock out sequential data words.When the memory address limit is reached,the data word address will “roll over”and the sequential read will continue.The sequential read operation is terminated when the microcontroller does not respond with a zero but does generate a following stop condition (see <blue>Figure 6-6on page 11).Figure 6-1.Device AddressFigure 6-2.Byte WriteMSBLSB1 0 1 0 P2 P 1 P 0 R/W16K ST A R TW R I T ES T O PDEVICE

For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .General DescriptionThe MAX481, MAX483, MAX485, MAX487–MAX491, and MAX1487 are low-power transceivers for RS-485 and RS-422 communication. Each part contains one driver and one receiver. The MAX483, MAX487, MAX488, and MAX489feature reduced slew-rate drivers that minimize EMI and reduce reflections caused by improperly terminated cables,thus allowing error-free data transmission up to 250kbps.The driver slew rates of the MAX481, MAX485, MAX490,MAX491, and MAX1487 are not limited, allowing them to transmit up to 2.5Mbps.These transceivers draw between 120µA and 500µA of supply current when unloaded or fully loaded with disabled drivers. Additionally, the MAX481, MAX483, and MAX487have a low-current shutdown mode in which they consume only 0.1µA. All parts operate from a single 5V supply.Drivers are short-circuit current limited and are protected against excessive power dissipation by thermal shutdown circuitry that places the driver outputs into a high-imped-ance state. The receiver input has a fail-safe feature that guarantees a logic-high output if the input is open circuit.The MAX487 and MAX1487 feature quarter-unit-load receiver input impedance, allowing up to 128 MAX487/MAX1487 transceivers on the bus. Full-duplex communi-cations are obtained using the MAX488–MAX491, while the MAX481, MAX483, MAX485, MAX487, and MAX1487are designed for half-duplex applications.________________________ApplicationsLow-Power RS-485 Transceivers Low-Power RS-422 Transceivers Level TranslatorsTransceivers for EMI-Sensitive Applications Industrial-Control Local Area Networks__Next Generation Device Features♦For Fault-Tolerant ApplicationsMAX3430: ±80V Fault-Protected, Fail-Safe, 1/4Unit Load, +3.3V, RS-485 TransceiverMAX3440E–MAX3444E: ±15kV ESD-Protected,±60V Fault-Protected, 10Mbps, Fail-Safe, RS-485/J1708 Transceivers♦For Space-Constrained ApplicationsMAX3460–MAX3464: +5V, Fail-Safe, 20Mbps,Profibus RS-485/RS-422 TransceiversMAX3362: +3.3V, High-Speed, RS-485/RS-422Transceiver in a SOT23 PackageMAX3280E–MAX3284E: ±15kV ESD-Protected,52Mbps, +3V to +5.5V, SOT23, RS-485/RS-422,True Fail-Safe ReceiversMAX3293/MAX3294/MAX3295: 20Mbps, +3.3V,SOT23, RS-855/RS-422 Transmitters ♦For Multiple Transceiver ApplicationsMAX3030E–MAX3033E: ±15kV ESD-Protected,+3.3V, Quad RS-422 Transmitters ♦For Fail-Safe ApplicationsMAX3080–MAX3089: Fail-Safe, High-Speed (10Mbps), Slew-Rate-Limited RS-485/RS-422Transceivers♦For Low-Voltage ApplicationsMAX3483E/MAX3485E/MAX3486E/MAX3488E/MAX3490E/MAX3491E: +3.3V Powered, ±15kV ESD-Protected, 12Mbps, Slew-Rate-Limited,True RS-485/RS-422 TransceiversMAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers______________________________________________________________Selection Table19-0122; Rev 8; 10/03Ordering Information appears at end of data sheet.M A X 481/M A X 483/M A X 485/M A X 487–M A X 491/M A X 1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSSupply Voltage (V CC ).............................................................12V Control Input Voltage (RE , DE)...................-0.5V to (V CC + 0.5V)Driver Input Voltage (DI).............................-0.5V to (V CC + 0.5V)Driver Output Voltage (A, B)...................................-8V to +12.5V Receiver Input Voltage (A, B).................................-8V to +12.5V Receiver Output Voltage (RO).....................-0.5V to (V CC +0.5V)Continuous Power Dissipation (T A = +70°C)8-Pin Plastic DIP (derate 9.09mW/°C above +70°C)....727mW 14-Pin Plastic DIP (derate 10.00mW/°C above +70°C)..800mW 8-Pin SO (derate 5.88mW/°C above +70°C).................471mW14-Pin SO (derate 8.33mW/°C above +70°C)...............667mW 8-Pin µMAX (derate 4.1mW/°C above +70°C)..............830mW 8-Pin CERDIP (derate 8.00mW/°C above +70°C).........640mW 14-Pin CERDIP (derate 9.09mW/°C above +70°C).......727mW Operating Temperature RangesMAX4_ _C_ _/MAX1487C_ A...............................0°C to +70°C MAX4__E_ _/MAX1487E_ A.............................-40°C to +85°C MAX4__MJ_/MAX1487MJA...........................-55°C to +125°C Storage Temperature Range.............................-65°C to +160°C Lead Temperature (soldering, 10sec).............................+300°CDC ELECTRICAL CHARACTERISTICS(V CC = 5V ±5%, T A = T MIN to T MAX , unless otherwise noted.)

The MAX481, MAX485, MAX490,MAX491, and MAX1487 can transmit and receive at data rates up to 2.5Mbps, while the MAX483, MAX487,MAX488, and MAX489 are specified for data rates up to 250kbps. The MAX488–MAX491 are full-duplex trans-ceivers while the MAX481, MAX483, MAX485, MAX487,and MAX1487 are half-duplex. In addition, Driver Enable (DE) and Receiver Enable (RE) pins are included on the MAX481, MAX483, MAX485, MAX487, MAX489,MAX491, and MAX1487. When disabled, the driver and receiver outputs are high impedance.MAX487/MAX1487:128 Transceivers on the BusThe 48k Ω, 1/4-unit-load receiver input impedance of the MAX487 and MAX1487 allows up to 128 transceivers on a bus, compared to the 1-unit load (12k Ωinput impedance) of standard RS-485 drivers (32 trans-ceivers maximum). Any combination of MAX487/MAX1487 and other RS-485 transceivers with a total of 32 unit loads or less can be put on the bus. The MAX481/MAX483/MAX485 and MAX488–MAX491 have standard 12k ΩReceiver Input impedance.Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers 8_______________________________________________________________________________________Figure 2.

The devices will not shut down unless both the driver and receiver are disabled.In shutdown, the devices typically draw only 0.1µA of supply current.RE and DE may be driven simultaneously; the parts are guaranteed not to enter shutdown if RE is high and DE is low for less than 50ns. If the inputs are in this state for at least 600ns, the parts are guaranteed to enter shutdown.For the MAX481, MAX483, and MAX487, the t ZH and t ZL enable times assume the part was not in the low-power shutdown state (the MAX485/MAX488–MAX491and MAX1487 can not be shut down). The t ZH(SHDN)and t ZL(SHDN)enable times assume the parts were shut down (see Electrical Characteristics ).It takes the drivers and receivers longer to become enabled from the low-power shutdown state (t ZH(SHDN ), t ZL(SHDN)) than from the operating mode (t ZH , t ZL ). (The parts are in operating mode if the –R —E –,DE inputs equal a logical 0,1 or 1,1 or 0, 0.)Driver Output ProtectionExcessive output current and power dissipation caused by faults or by bus contention are prevented by two mechanisms. A foldback current limit on the output stage provides immediate protection against short cir-cuits over the whole common-mode voltage range (see Typical Operating Characteristics ). In addition, a ther-mal shutdown circuit forces the driver outputs into a high-impedance state if the die temperature rises excessively.Propagation DelayMany digital encoding schemes depend on the differ-ence between the driver and receiver propagation delay times. Typical propagation delays are shown in Figures 15–18 using Figure 14’s test circuit.The difference in receiver delay times, | t PLH - t PHL |, is typically under 13ns for the MAX481, MAX485,MAX490, MAX491, and MAX1487 and is typically less than 100ns for the MAX483 and MAX487–MAX489.The driver skew times are typically 5ns (10ns max) for the MAX481, MAX485, MAX490, MAX491, and MAX1487, and are typically 100ns (800ns max) for the MAX483 and MAX487–MAX489.MAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers______________________________________________________________________________________1110dB/div0Hz5MHz500kHz/div10dB/div0Hz5MHz500kHz/divFigure 12.

These parts can also be used as line repeaters, with cable lengths longer than 4000 feet, as shown in Figure 23.To minimize reflections, the line should be terminated at both ends in its characteristic impedance, and stub lengths off the main line should be kept as short as possi-ble. The slew-rate-limited MAX483 and MAX487–MAX489are more tolerant of imperfect termination.MAX481/MAX483/MAX485/MAX487–MAX491/MAX1487Low-Power, Slew-Rate-Limited RS-485/RS-422 Transceivers______________________________________________________________________________________13DIV Y -V ZRO5V 0V1V0V -1V5V 0V2µs/divFigure 19.

General DescriptionThe MAX4561/MAX4568/MAX4569 are low-voltage,ESD-protected analog switches. The normally open (NO) and normally closed (NC) inputs are protected against ±15kV electrostatic discharge (ESD) without latchup or damage, and the COM input is protected against 2.5kV ESD.These switches operate from a single +1.8V to +12V supply. The 70Ωat 5V (120Ωat 3V) on-resistance is matched between channels to 2Ωmax, and is flat (4Ωmax) over the specified signal range. The switches can handle Rail-to-Rail ® analog signals. Off-leakage current is only 0.5nA at +25°C and 5nA at +85°C. The digital input has +0.8V to +2.4V logic thresholds, ensuring TTL/CMOS-logic compatibility when using a single +5V supply. The MAX4561 is a single-pole/double-throw (SPDT) switch. The MAX4568 NO and MAX4569 NC are single-pole/single-throw (SPST) switches.The MAX4561 is available in a 6-pin SOT23 package,and the MAX4568/MAX4569 are available in 5-pin SOT23 packages.________________________ApplicationsHigh-ESD Environments Battery-Powered Systems Audio and Video Signal Routing Low-Voltage Data-Acquisition Systems Sample-and-Hold Circuits Communications CircuitsFeatureso ESD-Protected NO, NC±15kV—Human Body Model±15kV—IEC 1000-4-2, Air-Gap Discharge ±8kV—IEC 1000-4-2, Contact Discharge o Guaranteed On-Resistance70Ω+5V Supply120Ωwith Single +3V Supplyo On-Resistance Match Between Channels (2Ωmax)o Low On-Resistance Flatness: 4Ωmax o Guaranteed Low Leakage Currents0.5nA Off-Leakage (at T A = +25°C)0.5nA On-Leakage (at T A = +25°C)o Guaranteed Break-Before-Make at 5ns(MAX4561 only)o Rail-to-Rail Signal Handling Capabilityo TTL/CMOS-Logic Compatible with +5V Supplies o Industry Standard Pin-OutsMAX4561 Pin Compatible with MAX4544MAX4568/MAX4569 Pin Compatible with MAX4514/MAX4515MAX4561/MAX4568/MAX4569±15kV ESD-Protected, Low-Voltage,SPDT/SPST, CMOS Analog Switches________________________________________________________________Maxim Integrated Products 1Pin Configurations/Functional Diagrams/Truth Tables19-1714; Rev 0; 4/00For free samples and the latest literature, visit or phone 1-800-998-8800.For small orders, phone 1-800-835-8769.Ordering InformationRail-to-Rail is a registered trademark of Nippon Motorola, Ltd.查询MAX4561EUT-T供应商M A X 4561/M A X 4568/M A X 4569±15kV ESD-Protected, Low-Voltage,SPDT/SPST, CMOS Analog Switches 2_______________________________________________________________________________________ABSOLUTE MAXIMUM RATINGSELECTRICAL CHARACTERISTICS —Single +5V Supply(V+ = +4.5V to +5.5V, V IH = +2.4V, V IL = +0.8V, T A = T MIN to T MAX , unless otherwise specified.

To accomplish this, bidirectional SCRs are included on-chip between these terminals. When the voltages at these terminals go Beyond-the-Rails ™,the corresponding SCR turns on in a few nanoseconds and bypasses the surge safely to ground. This method is superior to using diode clamps to the supplies because unless the supplies are very carefully decou-pled through low-ESR capacitors, the ESD current through the diode clamp could cause a significant spike in the supplies. This may damage or compromise the reliability of any other chip powered by those same supplies.There are diodes from NC/NO to the supplies in addi-tion to the SCRs. A resistance in series with each of these diodes limits the current into the supplies during an ESD strike. The diodes protect these terminals from overvoltages that are not a result of ESD strikes. These diodes also protect the device from improper power-supply sequencing.Once the SCR turns on because of an ESD strike, it remains on until the current through it falls below its “holding current.” The holding current is typically 110mA in the positive direction (current flowing into the NC/NO terminal) at room temperature (see SCR Holding Current vs.Temperature in the Typical Operating Characteristics ). Design the system so that any sources connected to NC/NO are current-limited to a value below the holding current to ensure the SCR turns off when the ESD event is finished and normal operation resumes. Also, remember that the holding current varies significantly with temperature. The worst case is at +85°C when the holding currents drop to 70mA. Since this is a typical number to guarantee turn-off of the SCRs under all conditions, the sources con-nected to these terminals should be current-limited to no more than half this value. When the SCR is latched,the voltage across it is approximately 3V. The supply voltages do not affect the holding current appreciably.The sources connected to the COM side of the switches need not be current limited since the switches turn off internally when the corresponding SCR(s) latch.Even though most of the ESD current flows to GND through the SCRs, a small portion of it goes into V+.Therefore, it is a good idea to bypass the V+ with 0.1µF capacitors directly to the ground plane.ESD protection can be tested in various ways. Inputs are characterized for protection to the following:•±15kV using the Human Body Model•±8kV using the Contact Discharge method speci-fied in IEC 1000-4-2 (formerly IEC 801-2)•±15kV using the Air-Gap Discharge method speci-fied in IEC 1000-4-2 (formerly IEC 801-2)ESD Test ConditionsContact Maxim Integrated Products for a reliability report that documents test setup, methodology, and results.Human Body ModelFigure 6 shows the Human Body Model, and Figure 7shows the waveform it generates when discharged into a low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of interest, which can be dis-charged into the test device through a 1.5k Ωresistor.IEC 1000-4-2The IEC 1000-4-2 standard covers ESD testing and performance of finished equipment; it does not specifi-cally refer to integrated circuits. The MAX4561 enables the design of equipment that meets Level 4 (the highest level) of IEC 1000-4-2, without additional ESD protec-tion components.The major difference between tests done using the Human Body Model and IEC 1000-4-2 is higher peak cur-rent in IEC 1000-4-2. Because series resistance is lower in the IEC 1000-4-2 ESD test model (Figure 8), the ESD withstand voltage measured to this standard is generally lower than that measured using the Human Body Model.Figure 9 shows the current waveform for the ±8kV IEC 1000-4-2 Level 4 ESD Contact Discharge test.The Air-Gap test involves approaching the device with a charged probe. The Contact Discharge method connects the probe to the device before the probe is energized.Chip InformationPROCESS: CMOSBeyond-the-Rails is a trademark of Maxim Integrated Products.TRANSISTOR COUNT: 69(MAX4561)39(MAX4568/MAX4569)M A X 4561/M A X 4568/M A X 4569±15kV ESD-Protected, Low-Voltage,SPDT/SPST, CMOS Analog Switches 8_______________________________________________________________________________________Figure 1.

The enhanced ESD structure protects all transmitter outputs and receiver inputs to ±15kV using IEC 1000-4-2 Air-G ap Discharge, ±8kV using IEC 1000-4-2 Contact Discharge (±9kV for MAX3246E), and ±15kV using the Human Body Model. The logic and receiver I/O pins of the MAX3237E are protected to the above standards, while the transmit-ter output pins are protected to ±15kV using the Human Body Model.A proprietary low-dropout transmitter output stage delivers true RS-232 performance from a +3.0V to +5.5V power supply, using an internal dual charge pump. The charge pump requires only four small 0.1µF capacitors for opera-tion from a +3.3V supply. Each device guarantees opera-tion at data rates of 250kbps while maintaining RS-232output levels. The MAX3237E guarantees operation at 250kbps in the normal operating mode and 1Mbps in the MegaBaud™ operating mode, while maintaining RS-232-compliant output levels.The MAX3222E/MAX3232E have two receivers and two transmitters. The MAX3222E features a 1µA shutdown mode that reduces power consumption in battery-pow-ered portable systems.

The charge pump operates in discontinuous mode; if the output voltages are less than 5.5V, the charge pump is enabled, and if the output voltages exceed 5.5V, the charge pump is disabled. Each charge pump requires a flying capacitor (C1, C2) and a reservoir capacitor (C3, C4) to generate the V+ and V- supplies (Figure 1).RS-232 TransmittersThe transmitters are inverting level translators that con-vert TTL/CMOS-logic levels to ±5V EIA/TIA-232-compli-ant levels.The MAX3222E/MAX3232E/MAX3237E/MAX3241E/MAX3246E transmitters guarantee a 250kbps data rate with worst-case loads of 3k Ωin parallel with 1000pF,providing compatibility with PC-to-PC communication software (such as LapLink™). Transmitters can be par-alleled to drive multiple receivers or mice.The MAX3222E/MAX3237E/MAX3241E/MAX3246E transmitters are disabled and the outputs are forcedinto a high-impedance state when the device is in shut-down mode (SHDN = G ND). The MAX3222E/MAX3232E/MAX3237E/MAX3241E/MAX3246E permit the outputs to be driven up to ±12V in shutdown.The MAX3222E/MAX3232E/MAX3241E/MAX3246E transmitter inputs do not have pullup resistors. Connect unused inputs to GND or V CC . The MAX3237E’s trans-mitter inputs have a 400k Ωactive positive-feedback resistor, allowing unused inputs to be left unconnected.MAX3237E MegaBaud OperationFor higher-speed serial communications, the MAX3237E features MegaBaud operation. In MegaBaud operating mode (MBAUD = V CC ), the MAX3237E transmitters guarantee a 1Mbps data rate with worst-case loads of 3k Ωin parallel with 250pF for +3.0V < V CC < +4.5V. For +5V ±10% operation, the MAX3237E transmitters guarantee a 1Mbps data rate into worst-case loads of 3k Ωin parallel with 1000pF.RS-232 ReceiversThe receivers convert RS-232 signals to CMOS-logic output levels. The MAX3222E/MAX3237E/MAX3241E/MAX3246E receivers have inverting three-state outputs.Drive EN high to place the receiver(s) into a high-impedance state. Receivers can be either active or inactive in shutdown (Table 1).Figure 1. Slew-Rate Test CircuitsLapLink is a trademark of Traveling Software.M A X 3222E /M A X 3232E /M A X 3237E /M A X 3241E †/M A X 3246EUp to 1Mbps, True RS-232 Transceivers10______________________________________________________________________________________The complementary outputs on the MAX3237E/MAX3241E (R_OUTB) are always active, regardless of the state of EN or SHDN . This allows the device to be used for ring indicator applications without forward biasing other devices connected to the receiver outputs. This is ideal for systems where V CC drops to zero in shutdown to accommodate peripherals such as UARTs (Figure 2).MAX3222E/MAX3237E/MAX3241E/MAX3246E Shutdown ModeSupply current falls to less than 1µA in shutdown mode (SHDN = low). The MAX3237E’s supply current falls to10nA (typ) when all receiver inputs are in the invalid range (-0.3V < R_IN < +0.3). When shut down, the device’s charge pumps are shut off, V+ is pulled down to V CC , V- is pulled to ground, and the transmitter out-puts are disabled (high impedance). The time required to recover from shutdown is typically 100µs, as shown in Figure 3. Connect SHDN to V CC if shutdown mode is not used. SHDN has no effect on R_OUT or R_OUTB (MAX3237E/MAX3241E).±15kV ESD ProtectionAs with all Maxim devices, ESD-protection structures are incorporated to protect against electrostatic dis-charges encountered during handling and assembly.The driver outputs and receiver inputs of the MAX3222E/MAX3232E/MAX3237E/MAX3241E/MAX3246E have extra protection against static electricity. Maxim’s engineers have developed state-of-the-art structures to protect these pins against ESD of ±15kV without damage.The ESD structures withstand high ESD in all states:normal operation, shutdown, and powered down. After an ESD event, Maxim’s E versions keep working without latchup, whereas competing RS-232 products can latch and must be powered down to remove latchup.Furthermore, the MAX3237E logic I/O pins also have ±15kV ESD protection. Protecting the logic I/O pins to ±15kV makes the MAX3237E ideal for data cable applications.SHDN T2OUTT1OUT5V/div2V/divV CC = 3.3V C1–C4 = 0.1μFFigure 3.

This model consists of a 100pF capacitor charged to the ESD voltage of interest,which is then discharged into the test device through a 1.5k Ωresistor.IEC 1000-4-2The IEC 1000-4-2 standard covers ESD testing and performance of finished equipment; it does not specifi-cally refer to integrated circuits. The MAX3222E/MAX3232E/MAX3237E/MAX3241E/MAX3246E help you design equipment that meets level 4 (the highest level)of IEC 1000-4-2, without the need for additional ESD-protection components.The major difference between tests done using the Human Body Model and IEC 1000-4-2 is higher peak current in IEC 1000-4-2, because series resistance is lower in the IEC 1000-4-2 model. Hence, the ESD with-stand voltage measured to IEC 1000-4-2 is generally lower than that measured using the Human Body Model. Figure 5a shows the IEC 1000-4-2 model, and Figure 5b shows the current waveform for the ±8kV IEC 1000-4-2 level 4 ESD Contact Discharge test. The Air-G ap Discharge test involves approaching the device with a charged probe. The Contact Discharge method connects the probe to the device before the probe is energized.Machine ModelThe Machine Model for ESD tests all pins using a 200pF storage capacitor and zero discharge resis-tance. Its objective is to emulate the stress caused by contact that occurs with handling and assembly during manufacturing. All pins require this protection during manufacturing, not just RS-232 inputs and outputs.Therefore, after PC board assembly, the Machine Model is less relevant to I/O ports.Table 2. Required Minimum Capacitor ValuesFigure 6a. MAX3241E Transmitter Output Voltage vs. Load Current Per TransmitterTable 3. Logic-Family Compatibility with Various Supply VoltagesMAX3222E/MAX3232E/MAX3237E/MAX3241E †/MAX3246EUp to 1Mbps, True RS-232 TransceiversApplications InformationCapacitor SelectionThe capacitor type used for C1–C4 is not critical for proper operation; polarized or nonpolarized capacitors can be used. The charge pump requires 0.1µF capaci-tors for 3.3V operation. For other supply voltages, see Table 2 for required capacitor values. Do not use val-ues smaller than those listed in Table 2. Increasing the capacitor values (e.g., by a factor of 2) reduces ripple on the transmitter outputs and slightly reduces power consumption. C2, C3, and C4 can be increased without changing C1’s value. However, do not increase C1without also increasing the values of C2, C3, C4,and C BYPASS to maintain the proper ratios (C1 to the other capacitors).When using the minimum required capacitor values,make sure the capacitor value does not degradeexcessively with temperature. If in doubt, use capaci-tors with a larger nominal value. The capacitor’s equiv-alent series resistance (ESR), which usually rises at low temperatures, influences the amount of ripple on V+and V-.Power-Supply DecouplingIn most circumstances, a 0.1µF V CC bypass capacitor is adequate. In applications sensitive to power-supply noise, use a capacitor of the same value as charge-pump capacitor C1. Connect bypass capacitors as close to the IC as possible.Operation Down to 2.7VTransmitter outputs meet EIA/TIA-562 levels of ±3.7V with supply voltages as low as 2.7V.Figure 6b.

As they become active, the two trans-mitter outputs are shown going to opposite RS-232 levels (one transmitter input is high; the other is low). Each transmitter is loaded with 3k Ωin parallel with 2500pF.The transmitter outputs display no ringing or undesir-able transients as they come out of shutdown. Note thatthe transmitters are enabled only when the magnitude of V- exceeds approximately -3.0V.Mouse DrivabilityThe MAX3241E is designed to power serial mice while operating from low-voltage power supplies. It has been tested with leading mouse brands from manu-facturers such as Microsoft and Logitech. The MAX3241E successfully drove all serial mice tested and met their current and voltage requirements.MAX3222E/MAX3232E/MAX3237E/MAX3241E †/MAX3246EUp to 1Mbps, True RS-232 TransceiversFigure 6a shows the transmitter output voltages under increasing load current at +3.0V. Figure 6b shows a typical mouse connection using the MAX3241E.High Data RatesThe MAX3222E/MAX3232E/MAX3237E/MAX3241E/MAX3246E maintain the RS-232 ±5V minimum transmit-ter output voltage even at high data rates. Figure 7shows a transmitter loopback test circuit. Figure 8shows a loopback test result at 120kbps, and Figure 9shows the same test at 250kbps. For Figure 8, all trans-mitters were driven simultaneously at 120kbps into RS-232 loads in parallel with 1000pF. For Figure 9, a single transmitter was driven at 250kbps, and all transmitters were loaded with an RS-232 receiver in parallel with 1000pF.The MAX3237E maintains the RS-232 ±5.0V minimum transmitter output voltage at data rates up to 1Mbps.Figure 10 shows a loopback test result at 1Mbps with MBAUD = V CC . For Figure 10, all transmitters were loaded with an RS-232 receiver in parallel with 250pF.Interconnection with 3V and 5V LogicThe MAX3222E/MAX3232E/MAX3237E/MAX3241E/MAX3246E can directly interface with various 5V logic families, including ACT and HCT CMOS. See Table 3for more information on possible combinations of inter-connections.UCSP ReliabilityThe UCSP represents a unique packaging form factor that may not perform equally to a packaged product through traditional mechanical reliability tests. UCSP reliability is integrally linked to the user’s assembly methods, circuit board material, and usage environ-ment. The user should closely review these areas when considering use of a UCSP package. Performance through Operating Life Test and Moisture Resistance remains uncompromised as the wafer-fabrication process primarily determines it.Mechanical stress performance is a greater considera-tion for a UCSP package. UCSPs are attached through direct solder contact to the user’s PC board, foregoing the inherent stress relief of a packaged product lead frame. Solder joint contact integrity must be consid-ered.

CurrentShuntMonitors

Current Shunt MonitorsPowerSupply• Current shunt monitors are also referred to as current sense amplifiers.• Current shunt monitors are designed to monitor the current flow by measuring the voltage drop across a resistor placed in the current path.• Current sense amplifiers tend to be easier to design, more precise, less prone to noise and lower cost than magnetic current sensors.Common Mode Range:This specification defines the DC voltage range at the input of an amplifier with respect to ground. Current shunt monitors are typically designed to accept common mode voltages well beyond the chip supply voltage. For example, the INA282is capable of accepting a common mode voltage from -14V to +80V while running on a supply as low as 2.7V. Offset Voltage:The differential DC error at the inputof the amplifier. Historically, to reducethe impact of amplifiers with highoffsets, larger shunt resistors are usedto increase the measured voltagedrop. Today, TI is able to offer currentsensing solutions with offsets as lowas 10µV, enabling higher precisionmeasurements at low currents and theuse of smaller shunt resistances forimproved system efficiency.CMRR(Common Mode Rejection Ratio):CMRR is the ability of the amplifierto reject signals common to thedifferential inputs. This is importantin the ability to measure small signalssuperimposed upon a large voltage.TI’s portfolio offers solutions withCMRR as high as 140dB.Digital Output:Simple all-in-one solution integrating the ADC/MUX with programmable switching. Provides measurements in amps, volts and watts across the I2C interface for a complete power monitoring solution.REFOUTVVVoltage Output: High precision, lowest power andindustry’s smallest form factors. Fixed gain optionsranging from 14V/V to 1000V/V. Variable gain may beset through an external resistor.Current Output: Variable gain set throughexternal resistor. Highest bandwidth options.VOUTVVOutput TypesKey ParametersWhat are Current Shunt Monitors?CPower Advantages:• Typically only requires an op amp such as OPA335Straightforward, easy Inexpensive Disadvantages:• Undesirable resistance in the load’s ground path• Cannot detect fault conditions (short/open circuits)• Requires precision external components to achieve and maintain high accuracyAdvantages over op amps as a low-side monitor :• Integrated gain resistorsExcellent matching that requires more expensive external precision resistors with an op amp approach Integrated resistors approachreduces board space requirements Disadvantages over op amps:• Fixed gain settings reduce flexibility in maximizing the full-scale range of the following ADC stageLow-side current sensing techniques connect the current sense element between the load and ground.When to choose low-side sensing: Always choose low-side sensing if the system can tolerate disturbances on the ground path.High-side monitors are designed to accommodate input voltages that exceed the power supply voltage. However, many of our current shunt monitors havecommon-mode ranges that include or even go below ground. This makes them excellent low-side current shunt monitors as well.Advantages:• Eliminates ground disturbances associated with low-side sensing • Able to detect fault conditions Disadvantages:• Difficult to use standard op amp. Resistors must be precisely matched to obtain acceptable common mode rejection ratios (CMRR)A 0.01% deviation in resistor value lowers the CMRR to 86dB approachA 0.1% deviation in resistor value lowers the CMRR to 66dBA 1% deviation in resistor value lowers the CMRR to 46dB• Must withstand very high, dynamic changes in common mode voltageHigh-side current sensing techniques connect the current sense element between the supply and the load.When to choose high-side sensing:• System cannot tolerate ground disturbance of low side sensing • System needs to be able to identify shorts to groundCHigh-Side MeasurementsLow-Side Measurements With a High-Side MonitorLow-Side Measurements2C• For small differential signals at the input, the error is dominated by the amplifier’s offset voltage. Low input offsets are critical to achieving accurate measurements at the low end of the dynamic range.• For large differential signals at the input, the error is dominated by theamplifier’s gain error.0%2%4%6%8%10%0102030405060708090100T o t a l E r r o r %Differential Voltage (mV)10µV; 0.1%10µV; 1%1mV; 1%1mV; 5%Offset; Gain ErrorExtending the Common Mode RangeExample 1: MOSFET and ZenerRSSupply +160 to +200VExample 3: Isolated SPI InterfaceExample 4: Isolated I 2C InterfaceExample 2: Current FollowerWith additional circuitry, current shunts can be configured to operate beyond the specified common mode range by using one of the following techniques.Total ErrorData (SCL)ShuntINA226:Highest precision solution on the market• Integrated ADC and MUX with programmable sampling• Common mode range = 0V to 36V • Offset (max) = 10µV• Gain error (max) = 0.1%• CMRR (typ) = 140dB• Lower cost alternative: INA219, INA230INA210: Precision voltage output • Gain options: 50V/V, 100V/V,200V/V, 500V/V, 1000V/V• Common mode range: –0.3V to 26V • Offset (max) = 35µV• Gain error (max) = 1%• CMRR (typ) = 140dB• Lower cost alternative: INA199INA216: Designed for portable battery powered applications• Gain options: 25V/V, 50V/V, 100V/V, 200V/V• Common mode range = 1.8V to 5.5V • Offset (max) = 75µV• Gain error (max) = 0.2%• Quiescent current = 25µA• CMRR (typ) = 108dB• 0.76 x 0.76mm WCSP or QFN package availableINA3221: Triple-channel digital shunt and bus voltage monitor• Integrated ADC and MUX with programmable sampling• Common mode range = 0V to 26V • Offset error (max) = 80µV• Gain error (max): 0.5%• Quiescent current = 450µA INA282:Widest common moderange + precision• Common mode range = -14V to 80V• Offset (max) = 70µV• Offset drift (max) = 1.5µV/ºC• Gain error (max) = 1.4%• CMRR (typ) = 140dB• Lower cost alternative: INA193,LMP8601LMP8640:High bandwidth andhigh voltage• Bandwidth = 950kHz• Common mode range: -2V to 76V• Offset (max) = 900µV• Gain error = 0.25%• CMRR (min) = 103dB• Lower cost alternative: LMP8645AMC1200: 4kV isolated amplifier• Offset (max) = 1.5mV• Offset drift (max) = 10µV/K• Gain error (max) = 1%• CMRR (typ) = 108dBLMP8481:High voltage• Bandwidth = 270kHz• Common mode range = 4.0V to 76V• Offset (max) = 400µV• Gain error (max) = 1.2%• CMRR (typ) = 124dB• Lower cost alternative: LMP8480LMP92064: Simultaneous samplingcurrent/voltage monitor• 125ksamples/sec• Bandwidth = 70kHz• Offset (max) = 60µV• Gain error (max) = 0.75%INA225:Programmable gain,zero-drift current sense amplifier• 4-pin selectable gain settings• Bandwidth = 100kHz @ 100V/V• Offset (max) = 125µV• Gain error (max) = 0.50%INA300:Over current detector• Input/output response time = 10µs• Programmable threshold:0 to 250mV• Hysteresis of 2, 5, or 10mVFeatured ProductsThe platform bar and E2E are trademarks of Texas Instruments.

Transmission of the proportional currentoutput may be accomplished by using inexpensive copper wire.1Figure 1-1 TX905, TX906TransmitterFigure 1-2 Dimensions (in inches)2The TX905 or TX906 transmitter is normally powered by an unregulated power supply as shown in Figure 1-3. Theproportionally-transmitted signal begins at 4 mA, at the low end ofits voltage range, and increases to 20 mA, at the high end of itsvoltage range.3Figure 1-3 TX94 RTD Transmitter 4The TX905 or TX906 two-wire transmitter works with voltage inputs and provides an output current of 4-20 mA proportional to the input. Two copper wires now carry the 4-20 mA output signal and dc voltage to operate the transmitter, thereby reducing possible noise pick-up errors. The TX905 or TX906 does NOT provide isolation between its input and the 4-20 mA output.51.2 Features• 4-20 mA output• ע0.1% full-scale accuracy• Upscale break protection• Low Cost6Model Number DescriptionTX905Field rangeable millivolt transmitter, 4 to 64 mVTX906-V1Field rangeable millivolt transmitter, 0.04 to 0.64 mV TX906-V2Field rangeable millivolt transmitter, 0.40 to 6.40 mV TX906-V3Field rangeable millivolt transmitter, 4 to 64 mV782.1 Mounting the TX905 or TX06The TX905 or TX906 transmitter may be:1. surface mounted,2. mounted inside a protection head (refer to Figure 2-1), or3. installed into the OMEGA mounting track (part number RT)using an OMEGA mounting bracket (part number TX90-BR).4. installed into standard 35mm DIN rail using an OMEGA DIN rail mounting adapter (part number TX-90-DIN).Figure 2-2 shows the RT mounting track.

Connect the RTD element to the input terminals as shown.15Figure 2-5 Wiring Diagram for the TX905 or TX906O N163.1 Equipment Required• Precision voltage source, such as the OMEGA®CL8301 dc voltage and Current Calibrator• Precision DMM capable of measuring mA, within 0.001 mA resolution and ע0.002 mA accuracy.173.2 Calibration Procedures (Refer to Figure 3-1)Connect the calibration equipment according to Figure 3-1.Standard copper test leads are used.To check or adjust the calibration:1. Locate the Z (zero) and S (span) potentiometers.2. Select, from Table 3-1, the correct dip switch settings for your desired range for the TX905 or TX906.If a Precision Voltage Simulator is used, such as the OMEGA ®Model CL8301 Precision Calibrator, select the Voltage Input Z(zero) and S (span) values.18TX905, the Z input is 10.000 mV and the S input is 50.000 mV.3. Set the calibrator to the selected Z (zero) voltage value.Adjust the Z potentiometer to read 4.000 mA on the monitoring instrument.4. Set the calibrator to the selected S (span) voltage value.Adjust the S potentiometer to read 20.000 mA on the monitoring instrument.5. Repeat steps 3 and 4, as required, until the readaings are exactly 4.000 mA and 20.000 mA. This procedure is necessary since there is interaction between the two potentiometers.Figure 3-1 TX905 or TX906 Voltage Calibration Set-Up1921Malfunction or incorrect operation may be caused by:1. Incorrect Readings:Check for improper wiring (Refer to Figure 2-5)2. Loose or broken wires:Check each terminal connection for tightness. Move each wire-back and forth and note any changes in operation.3. Too high a load resistance in the output current loop or too low a current rating on the power supply:a)Measure the total resistance of each device (excluding the transmitter and power supply) in the 20 mA loop, including the resistance of the lead wires.22formula: Loop Resistance (maximum) = V supply–7VFor example, a 24V power supply would give a maximum loop resistance of: 17V/0.020A= 850 ohms.c)Make sure the power supply is rated for at least 28 mAtimes the number of TX905 or TX906 transmitters being powered. For example, if the supply is powering five transmitters, the supply should be rated for at least 140 mA.0.020ATX90-BR Mounting BracketPSU-24B Unregulated Power Supply, 24 VoltsTX828Process Loop-Powered IndicatorRT48" Mounting TrackTX90-DIN DIN Rail Mounting AdapterRAIL -35-2 6.5' Section 35mm DIN Rail2324GeneralSize: 1.75" dia.

The pressure peaks are absorbed by a sufficient margin of safety.Duplex filters can be serviced without interruption of operation. The upper part has a three-way-change-over valve which allows to change-over the flow from the dirty filter-side to the clean filter-side without interrupting the operation. The change-over procedure does not lead to a cross sectional contraction. Prior to the change-over procedure a built-in pressure balance valve equalizes the housing pressure. After change-over the pressure balance valve is to be closed again. The closed filter-side has to be air-bled by vent III respectively by vent IV. Then change filter element. After screw in the filter bowl the pressure balance has to be opened shortly and the just serviced filter-side has to be air-bled. Filter elements are available down to a filter fineness of 5 µm(C ).Eaton filter elements are known for high intrinsic stability and an excellent filtration capability, a high dirt-retaining capacity and a long service life.Eaton filter elements are available up to a pressure resistance of ∆p 2320 PSI and a rupture strength of ∆p 3625 PSI.Eaton filter can be used for petroleum-based fluids, HW emulsions, water glycols, most synthetic fluids and lubrication fluids. Consult factory for specific fluid applications.The internal valve is integrated into the filter head.

Both devices include an internal 1.5k Ωpullup resistor that connects and disconnects D+to VTRM (see the Functional Diagram ).The MAX3344E/MAX3345E are tolerant to power seq-uencing with either V CC > V L or V L > V CC . Additionally,the USB I/O, D+ and D-, and V CC are ESD protected to ±15kV. The MAX3344E/MAX3345E can receive USB power (V CC ) directly from the USB connection and operate with logic supplies (V L ) down to 1.65V, while still meeting the USB physical layer specifications. The MAX3344E/MAX3345E support full-speed (12Mbps)USB specification 2.0 operation.The MAX3344E/MAX3345E have an enumerate feature that functions when power is applied. Driving ENUM low disconnects the internal 1.5k Ωpullup resistor from D+enumerating the USB. This is useful if changes in commu-nication protocol are required while power is applied, and while the USB cable is connected.±15kV ESD-Protected USB Transceivers in UCSP with USB Detect 6_______________________________________________________________________________________Power-Supply ConfigurationsNormal Operating ModeConnect V L and V CC to system power supplies (Table 1). Connect V L to a +1.65V to +3.6V supply. Connect V CC to a +4.0V to +5.5V supply. Alternatively, the MAX3344E/MAX3345E can derive power from a single Li+ battery. Connect the battery to V CC.V VTRM remains above +3.0V for V CC as low as +3.1V.Additionally, the MAX3344E/MAX3345E can derive power from a 3.3V ±10% voltage regulator. Connect V CC and VTRM to an external +3.3V voltage regulator. Disable ModeConnect V CC to a system power supply and leave V L unconnected or connect to GND. D+ and D- enter a tri-state mode and V CC consumes less than 20µA of supply current. D+ and D- withstand external signals up to +5.5V in disable mode (Table 2).Sharing ModeConnect V L to a system power supply and leave V CC (or V CC and VTRM) unconnected or connect to GND. D+and D- enter a tri-state mode, allowing other circuitry to share the USB D+ and D- lines, and V L consumes less than 20µA of supply current. D+ and D- withstand exter-nal signals up to +5.5V in sharing mode (Table 2).Device ControlD+ and D-D+ and D- are the USB-side transmitter I/O connec-tions, and are ESD protected to ±15kV using the Human Body Model, ±10kV using IEC 1000-4-2 Air-Gap Discharge, and ±8kV using IEC 1000-4-2 Contact Discharge, making the MAX3344E/MAX3345E ideal for applications where a robust transmitter is required. A 23.7Ωresistor is required on D+ and D- for normal operation (see the External Resistors section).ENUMUSB specification 2.0 requires a 1.5k Ωpullup resistor on D+ for full-speed (12Mbps) operation. Controlled by enumerate (ENUM), the MAX3344E/MAX3345E provide this internal 1.5k Ωresistor. Drive ENUM high to connect the pullup resistor from D+ to VTRM. Drive ENUM low to disconnect the pullup resistor from D+ to VTRM.VPO/VMO, VPI/VMI, and OEThe MAX3344E/MAX3345E system-side inputs are VPO and VMO. Data comes into the MAX3344E/MAX3345E through VPO and VMO. VPO and VMO operate either differentially with VPO as the positive terminal and VMO as the negative terminal, or single ended with VPO as the data input (see the MODE section).MAX3344E/MAX3345E±15kV ESD-Protected USB Transceiversin UCSP with USB Detect_______________________________________________________________________________________7**High or low.M A X 3344E /M A X 3345E±15kV ESD-Protected USB Transceivers in UCSP with USB Detect 8_______________________________________________________________________________________The MAX3344E/MAX3345E system-side outputs are VPI, VMI, and RCV. The MAX3344E/MAX3345E send data through VPI, VMI, and RCV. VPI and VMI are out-puts to the single-ended receivers and RCV is the out-put of the differential receiver.Output enable (OE ) controls data transmission. Drive OE low to enable data transmission on D+ and D-. Drive OE high to disable data transmission or receive data.MODEMODE is a control input that selects whether differential or single-ended logic signals are recognized by the system side of the MAX3344E/MAX3345E. Drive MODE high to select differential mode with VPO as the positive terminal and VMO as the negative terminal. Drive MODE low to select single-ended mode with VPO as the data input (Table 3).VTRMVTRM is the 3.3V output of the internal linear voltage regulator. VTRM powers the internal circuitry of the USB side of the MAX3344E/MAX3345E. Connect a 1µF (min)low-ESR ceramic or plastic capacitor from VTRM to GND, as close to VTRM as possible. Do not use VTRM to power external circuitry.V CCBypass V CC to GND with a 1µF ceramic capacitor as close to the device as possible. If V CC drops below the USB detect threshold, supply current drops below 20µA avoiding excessive V CC current consump-tion, and D+/D- enter a high-impedance state allowing other devices to drive the lines.USB DetectUSB detect output (USB_DET) signals that V CC is pre-sent. A high at USB_DET indicates that V CC is present,while a low at USB_DET indicates that V CC is not pre-sent. The MAX3344E USB_DET threshold is between 3.6V (min) and 4V (max), while the MAX3345E USB_DET threshold is between 1V (min) and 2.8V (max).SUSPSuspend (SUSP) is a control input. Force SUSP high to place the MAX3344E/MAX3345E in a low-power state.In this state, the quiescent supply current into V CC is less than 40µA and RCV goes low.In suspend mode, VPI and VMI remain active as receive outputs and VTRM stays on. The MAX3344E/MAX3345E continue to receive data from the USB,allowing the µP to sense activity on the D+/D- lines and wake up the MAX3344E/MAX3345E.The MAX3344E/MAX3345E can also transmit data to D+ and D- while in suspend mode. This function isused to signal a remote wake-up by driving a signal on D+ and D- for a period of 1ms to 15ms. In suspend mode, data can only be transmitted with full-speed slope control.Figure 1c.

Human Body ESD Test ModelsMAX3344E/MAX3345E±15kV ESD-Protected USB Transceiversin UCSP with USB Detect_______________________________________________________________________________________9Data TransferReceiving Data from the USBData received from the USB are output to VPI/VMI in either of two ways, differentially or single ended. To receive data from the USB, force OE high and SUSP low.Differential data arriving at D+/D- appear as differential logic signals at VPI/VMI, and as a single-ended logic sig-nal at RCV. If both D+ and D- are low, then VPI and VMI are low, signaling a single-ended zero condition on the bus; RCV remains in the last known state (Table 3).Transmitting Data to the USBThe MAX3344E/MAX3345E output data to the USB dif-ferentially on D+ and D-. The logic driving signals can be either differential or single ended. For sending differ-ential logic, force MODE high, force OE and SUSP low,and apply data to VPO and VMO. D+ then follows VPO,and D- follows VMO. To send single-ended logic sig-nals, force MODE, SUSP, and OE low, and apply data to VPO/VMO.ESD ProtectionTo protect the MAX3344E/MAX3345E against ESD, D+and D- have extra protection against static electricity to protect the device up to ±15kV. The ESD structures withstand high ESD in all states —normal operation,suspend, and powered down. For the 15kV ESD struc-tures to work correctly, a 1µF or greater capacitor must be connected from VTRM to GND.ESD protection can be tested in various ways; the D+and D- input/output pins are characterized for protection to the following limits:1) ±15kV using the Human Body Model2) ±8kV using the IEC 1000-4-2 Contact Discharge Method 3) ±10kV using the IEC 1000-4-2 Air-Gap Method ESD Test ConditionsESD performance depends on a variety of conditions.Contact Maxim for a reliability report that documents test setup, test methodology, and test results.Human Body ModelFigure 1a shows the Human Body Model, and Figure 1b shows the current waveform it generates when dis-charged into a low impedance. This model consists of a 100pF capacitor charged to the ESD voltage of interest,which is then discharged into the test device through a 1.5k Ωresistor.Figure 2. Enable and Disable Timing, TransmitterFigure 3. Mode 0 TimingFigure 4. Mode 1 TimingM A X 3344E /M A X 3345E±15kV ESD-Protected USB Transceivers in UCSP with USB DetectIEC 1000-4-2The IEC 1000-4-2 standard covers ESD testing and per-formance of finished equipment; it does not specifically refer to integrated circuits. The MAX3344E/MAX3345E help the user design equipment that meets level 4 of IEC 1000-4-2, without the need for additional ESD-protection components.The major difference between tests done using the Human Body Model and IEC 1000-4-2 is a higher peak current in IEC 1000-4-2, because series resistance is lower in the IEC 1000-4-2 model. Hence, the ESD with-stand voltage measured to IEC 1000-4-2 is generally lower than that measured using the Human Body Model.Figure 1c shows the IEC 1000-4-2 model.The Air-Gap Discharge Method involves approaching the device with a charged probe. The Contact Discharge Method connects the probe to the device before the probe is energized.Machine ModelThe Machine Model for ESD tests all pins using a 200pF storage capacitor and zero discharge resistance. Its objective is to emulate the stress caused by contact that occurs with handling and assembly during manufactur-ing. All pins require this protection during manufactur-ing. Therefore, after PC board assembly, the Machine Model is less relevant to I/O ports.Applications InformationExternal ComponentsExternal ResistorsTwo external 23.7Ω±1% to 27.4Ω±1%, 1/2W resistors are required for USB connection. Place the resistors in between the MAX3344E/MAX3345E and the USB connector on the D+ and D- lines (see the Typical Operating Circuit ).External CapacitorsUse three external capacitors for proper operation. Use a 0.1µF ceramic for decoupling V L , a 1µF ceramic for decoupling V CC , and a 1.0µF (min) ceramic or plastic filter capacitor on VTRM. Return all capacitors to GND.UCSP Applications InformationFor the latest application details on UCSP construction,dimensions, tape carrier information, printed circuit board techniques, bump-pad layout, and recommended reflow temperature profile, as well as the latest information on reliability testing results, refer to the Application Note UCSP—A Wafer-Level Chip-Scale Package available on Maxim’s website at /ucsp.MAX3344E/MAX3345E±15kV ESD-Protected USB Transceiversin UCSP with USB Detect______________________________________________________________________________________11Chip InformationTRANSISTOR COUNT: 2162PROCESS: BiCMOSM A X 3344E /M A X 3345E±15kV ESD-Protected USB Transceivers in UCSP with USB Detect 12______________________________________________________________________________________Figure 5.
