FUJITSU SEMICONDUCTORDATA SHEETCopyright©2010-2011 FUJITSU SEMICONDUCTOR LIMITED All rights reserved 2011.6Memory FRAM128 K (16 K × 8) Bit I 2CMB85RC128■DESCRIPTIONThe MB85RC128 is a FRAM (Ferroelectric Random Access Memory) Stand-Alone chip in a configuration of 16,384 words × 8 bits, using the ferroelectric process and silicon gate CMOS process technologies for forming the nonvolatile memory cells.The MB85RC128 adopts the two-wire serial interface.Unlike SRAM, the MB85RC128 is able to retain data without using a data backup battery.The read/write endurance of the nonvolatile memory cells used for the MB85RC128 has improved to be at least 1010 cycles, significantly out performing Flash memory and E 2PROM in the number.The MB85RC128 does not need a polling sequence after writing to the memory such as the case of Flash memory nor E 2PROM.■FEATURES•Bit configuration : 16,384 words × 8 bits •Operating power supply voltage : 2.7 V to 3.6 V •Operating frequency : 400 kHz (Max) •T wo-wire serial interface : I 2C-bus specification ver. 2.1 compliant, supports Standard-mode/Fast-mode.Fully controllable by two ports: serial clock (SCL) and serial data (SDA).•Operating temperature range : − 40 °C to +85 °C •Data retention : 10 years ( + 75 °C) •Read/write endurance : 1010 times •Package : Plastic / SOP , 8-pin (FPT -8P-M02)•Low power consumption : Operating current 0.15 mA (Max: @400 kHz), Standby current 5 μA (Typ)DS05–13110–3EMB85RC128■PIN FUNCTIONAL DESCRIPTIONSPinNumberPin Name Functional Description1 to 3A0 to A2Device Address pinsThe MB85RC128 can be connected to the same data bus up to 8 devices. Device addresses are used in order to identify each of the devices. Connect these pins to VDD pin or VSS pin externally. Only if the combination of VDD and VSS pins matches a device, an address and a code inputted from the SDA pin, the device operates. In the open pin state, A0, A1, and A2 pins are pulled-down and recognized as “L”.4VSS Ground pin5SDA Serial Data I/O pinThis is an I/O pin of serial data for performing bidirectional communication of address and writing or reading data of FRAM memory cell array. It is an open drain output that may be wired OR with other open drain or open collector sig-nals on the bus, so a pull-up resistance is required to be connected to the ex-ternal circuit.6SCL Serial Clock pinThis is a clock input pin for input/output serial data. Data is sampled on the ris-ing edge of the clock and output on the falling edge.7WP Write Protect pinWhen Write Protect pin is “H”, writing operation is disabled. When Write Protect pin is “L”, the entire memory region can be overwritten. Reading operation is al-ways enabled regardless of the Write Protect pin input level. The Write Protect pin is pulled down internally to VSS pin, therefore if the Write Protect pin is open, the pin status is detected as “L” (write enabled).8VDD Supply Voltage pinMB85RC128■I2C (Inter-Integrated Circuit)The MB85RC128 has a two-wire serial interface, supports the I2C bus, and operates as a slave device.The I2C bus defines communication roles of “master” and “slave” devices, with the master side holding the authority to initiate control. Furthermore, a I2C bus connection is possible where a single master device is connected to multiple slave devices. In this case, it is necessary to assign a unique device address to the slave device, the master side starts communication after specifying the slave to communicate by addresses.2MB85RC128■I2C COMMUNICATION PROTOCOLThe I2C bus is a two wire serial interface that uses a bidirectional data bus (SDA) and serial clock (SCL). A data transfer can only be initiated by the bus master, which will also provide the serial clock for synchroni-zation. The SDA signal should change while SCL is Low. However, as an exception, when starting and stopping communication sequence, SDA is allowed to change while SCL is High.•Start ConditionTo start read or write operations by the I2C bus, change the SDA input from High to Low while the SCL input is in the high state.•Stop ConditionTo stop the I2C bus communication, change the SDA input from Low to High while the SCL input is in the high state. In the reading operation, inputting the stop condition finishes reading and enters the standby state. In the writing operation, inputting the stop condition finishes inputting the rewrite data.Note : The FRAM device does not need the programming wait time (t WC) after issuing the Stop Condition during the write operation.MB85RC128■ACKNOWLEDGE (ACK)In the I2C bus, serial data including address or memory information is sent in units of 8 bits. The acknowledge signal indicates that every each 8 bits of the data is successfully sent and received. The information receiver side usually outputs “L” every time on the 9th SCL clock after each 8 bits are successfully transmitted. On the transmitter side, the bus is temporarily released to Hi-Z every time on this 9th clock to allow the acknowl-edge signal to be received and checked. During this Hi-Z-released period, the receiver side pulls the SDA line down to indicate “L” that the previous 8bits communication is successfully received.If the information receiver side detects Stop condition before driving the acknowledge “L”, the read operation ends and the I2C bus enters the standby state. If Stop condition is not sent, nor does the transmitter detect the acknowledge “L”, the bus remains in the released state “H” without doing anything.MB85RC128■DEVICE ADDRESS WORD (Slave address)Following the start condition, the bus master sends the 8bits device address word (Slave address) to start I2C communication. The device address word (8bits) consists of a device Type code (4bits), device address code (3bits), and a read/write code (1bit).•Device Type Code (4bits)The upper 4 bits of the device address word are a device type code that identifies the device type, and are fixed at “1010” for the MB85RC128.•Device Address Code (3bits)Following the device type code, the 3 bits of the device address code are input in order of A2, A1, and A0 pins. Each MB85RC128 is given a unique 3bits code on the device address pin (external hardware pin A2, A1, and A0). When the device address code is received by the slave device, the slave only responds if the hardware device address of which is equal to its unique 3bits code.•Read/Write Code (1bit)The 8th bit of the device address word is the R/W (read/write) code. When the R/W code is “L”, a write operation is enabled, and the R/W code is “H”, a read operation is enabled for the MB85RC128.MB85RC128■DATA STRUCTUREIn the I2C bus, the acknowledge “L” is output on the 9th bit after the 8 bits of the device and address word following the start condition. After confirming the acknowledge response at the slave, the I2C master outputs 8bits × 2 memory address to the I2C slave. When the memory address input ends, the slave again outputs the acknowledge “L”. After this operation, the I/O data follows in units of 8 bits, with the acknowledge “L”output after every 8bits.It is determined by the R/W code whether the data line is driven by the master or the slave. For a write operation the slave will accept 8bits from the master then send an acknowledge. If the master detects the acknowledge, the master will transfer the next 8bits. For a read operation the slave will place 8bits on the I2C bus, then wait for an acknowledge from the master.■FRAM ACKNOWLEDGE -- POLLING NOT REQUIREDThe MB85RC128 performs write operations at the same speed as read operations, so any waiting time for an ACK polling* does not occur. The write cycle takes no additional time.*: As to E2PROM, the Acknowledge Polling is performed as a progress check in the write programming step.It places NAK condition on the bus as of “not acknowledged” during the writing programming period. The busy status for the write programming is given from 9th ACK bit. That “done” condition is placed onto I2C bus by E2PROM I2C device and your program had to poll the bus in order to sense that condition.■WRITE PROTECT (WP)The entire memory array can be write protected using the Write Protect pin. When the Write Protect is set to “H”, the entire memory map will be write protected. When the write protect pin is “L”, all addresses may be overwritten.Note : The Write Protect pin is pulled down internally to VSS pin, therefore if the Write Protect pin is open, the pin status is detected as Low (write enabled).MB85RC128■COMMAND•Byte WriteIf the 8th bit of the device address word (R/W = 0) is sent following the start condition, the slave responds with an ACK. After this ACK, write addresses and data are sent in the same way, and the write ends byNote : In the MB85RC128, input “00” as the upper 2 bits of the MSB.•Page WriteIf additional 8bits are sent after the same command as Byte Write, a page write is performed. If more bytes are sent than will fit up to the end of the address, the address rolls over to 0000H. Therefore, if more than 8KBytes are sent, the data is overwritten in order starting from the start of the FRAM memory address that was written first. Because FRAM performs write operations at bus speed, the data will be written to FRAMNote : It is not necessary to take a period for internal write programming cycles from the buffer to the memory after the stop condition is generated.MB85RC128•Current Address ReadWhen the previous write or read operation finishes successfully up to the stop command and if the last accessed address is taken to be “n”, then the address at “n+1” is read by sending the following command unless turning the power off. If the end of the address range is reached internally, the address counter will•Random ReadThe one byte of data at the address as saved in the buffer can be read out synchronously to SCL by specifying the address in the same way as for a write, and then issuing another start condition and sending the Control Byte (R/W = 1).The final NACK is issued by the receiver that receives the data. In this case, this bit is issued by the masterMB85RC128•Sequential ReadData can be received continuously following the control byte after specifying the address the same as for Random Read. If the read exceeds the end of address for the MB85RC128, the internal read address automatically rolls over to 0000H.分销商库存信息: FUJITSUMB85RC128PNF-G-JNE1。

Recharge Voltage vs. Input Voltage Figure 13. Charge Current vs. Battery VoltageDETAILED OPERATING DESCRIPTIONOverviewRechargeable Li−Ion/Polymer batteries are normally charged with a constant current (CC) until the terminal voltage reaches a fixed voltage threshold, at which point a constant voltage (CV) is applied and the current drawn by the battery decays. The charging rate is determined by the specific rating of the battery. For example, if the battery is rated at 800 mA−hours, then the recommended maximum charge rate is 800 mA. For a severely discharged cell, it takes approximately 2.5−3.5 hours to recharge the battery at the maximum rate. So, when one charges at less than the maximum charge rate, the recharge time increases. Also, the battery should not be continuously charged or the battery could age faster than necessary. Because of this, Li−Ion charging systems need to stop charging within a prescribed time limit regardless of the charge rate.The NCP1835B is a fully integrated, stand−alone 1−cell Li−Ion charger which performs the primary battery charging functions and includes a timer which will terminate charging if the battery has not completed charging within a prescribed time period. The charging rate is user programmable up to 1.0 A and the end−of−charge timer is also programmable. The NCP1835B has a thermal foldback loop which reduces the charge rate if the junction temperature is exceeded. The device also includes several outputs which can be used to drive LED indicators or interface to a microprocessor to provide status information. The adapter providing power to the charger can be a standard fixed output voltage such as a 5.0 V wall adapter or it can be a simple current limited adapter.The NCP1835B comes in two versions with output voltage regulation thresholds of 4.2 or 4.242 V depending on the requirements of the specific battery pack being used. The user determines the charge current by selecting the resistor R ISEL and determines the length of the end−of−charge timeout timer by selecting the capacitor, C TIME.Charging OperationFigure 13 outlines the charging algorithm of the NCP1835B and Figure 14 graphically illustrates this. When the charger is powered up and the input voltage rises above the power−on, rising threshold (nominally 3.4 V), the charger initiates the charging cycle.The NCP1835B first determines the cell voltage. If it is less than the pre−charge threshold (2.8 V), the IC recognizes the battery as severely discharged. In this state, the NCP1835B pre−conditions (trickle charges) the battery by charging it at 10% of the full charge rate (I PC). This slow charge prevents the battery from being damaged from high fast charge currents when it is in a deeply discharged state. The battery voltage should be trickle charged up to 2.8 V before 1/8 of the preset end−of−charge time is expired. If it cannot reach this voltage, than the battery is possibly shorted or damaged. Therefore, the NCP1835B stops charging and the pre−charge timeout signal asserts the FAULT flag.Once the cell voltage crosses the pre−charge threshold, the device will transition to normal (full−rate) charging at 100% of the programmed full rate charge current (I FCHG). As the NCP1835B charges the battery, the cell voltage rises until it reaches the V REG threshold, (4.2 or 4.242 V). At the maximum charge rate, it normally takes about 1 hour to reach this point from a fully discharged state, and the battery will be approximately 70−80% recharged. At this point, the charge transitions to constant voltage mode where the IC forces the battery to remain at a constant voltage, V REG. During this constant voltage state, the current required to maintain V REG steadily decreases as the battery approaches full charge. Charge current eventually falls to a very low value as the battery approaches a fully charged condition.The NCP1835B monitors the current into the battery until it drops to 10% of the full charge rate. This is the End−of−Charge (EOC) threshold. Normally it takes 1.5−2.5 hours to reach this point. Once the NCP1835B reaches end−of−charge it opens the CFLG pin and enters the EOC state. The IC continues to charge the battery until it reaches TIMEOUT. At that point, the NCP1835B stops charging. If the system does not reach EOC during the TIMEOUT period, the NCP1835B views this as a system drops below the recharge threshold (which can occur if the battery is loaded), the IC reinitializes the charging sequence and begins a new charge cycle. The recharge voltage threshold, V RECH, is nominally 4.03 V.In the inhibit state, the NCP1835B continues to monitor the battery voltage, but does not charge the battery. Again, if the battery voltage drops below the recharge threshold the IC reinitializes the charging sequence and begins a new charge cycle.Figure 15. Typical Charging DiagramTrickleCC CV End ofTimeTimeTimeTimeTimeTimeTable 1. Charge StatusConditionCFLG FAULT Trickle, Constant Current and Constant Voltage Charge Low High End−of−Charge or Shutdown ModeHigh High Timeout Fault, V ISEL < 0.35 V or V ISEL > 1.4 VHighLowCharge Status Indicator (CFLG)CFLG is an open−drain output that indicates battery charging or End−of−Charge (EOC) status. It is pulled low when charging in constant current mode and constant voltage mode. It will be forced to a high impedance state when the charge current drops to I EOC. When the charger is in shutdown mode, CFLG will also stay in the high impedance state.Fault Indicator (FAULT)FAULT is an open−drain output that indicates that a charge fault has occurred. It has two states: low or high impedance. In a normal charge cycle, it stays in a high impedance state. At fault conditions, it will be pulled low and terminate the charge cycle. A timeout fault occurs when the full charge or pre−charge timeouts are violated, or if the voltage on ISEL is greater than 1.4 V or lower than 0.35 V. There are two ways to get the charger out of a fault condition and back to a normal charge cycle. One can either toggle the EN pin from GND to a floating state or reset the input power supply.Adapter Present Indicator (V2P8)V2P8 is an input power supply presence indicator. When the input voltage, V CC, is above the power on threshold (V RISE, nominally 3.4 V) and is also 100 mV above the battery voltage, it provides a 2.8 V reference voltage that can source up to 2.0 mA. This voltage can also be used to power a microprocessor I/O.Enable/Disable (EN)Pulling the EN pin to GND disables the NCP1835B. In shutdown mode, the internal reference, oscillator, and control circuits are all turned off. This reduces the battery drain current to less than 3.0 m A and the input supply current to 30 m A. Floating the EN pin enables the charger. Thermal FoldbackAn internal thermal foldback loop reduces the programmed charge current proportionally if the die temperature rises above the preset thermal limit (nominally 100°C). This feature provides the charger protection from over heating or thermal damage. Figure 16 shows the full charge current reduction due to die temperature increase across the thermal foldback limit. For a charger with a 1.0 A constant charge current, the charge current starts decreasing when the die temperature hits 100°C and is reduced to zero when the die temperature rises to 110°C.Figure 16.

特点
高压 JFET 快速启动与供电 超快 LED 启动时间(<100mS @85Vac) 内置 600V 功率 MOSFET 有源功率因数校正，高 PF 值，低 THD 高达 95%的系统效率 ± 3% LED 输出电流精度 优异的线电压调整率和负载调整率 电感电流临界连续模式 超低 (300uA) 工作电流 LED 短路/开路保护 电流采样电阻开路保护 逐周期电流限流 芯片供电欠压保护 自动重启功能 过热调节功能
RFBL 1.6V RFBL RFBH VOVP
其中， RFBL 是反馈网络的下分压电阻 RFBH 是反馈网络的上分压电阻 VOVP 是输出电压过压保护设定点 推荐 FB 下分压电阻设置在 5.1KΩ 或更小的值。 为了加强 FB 节点抗噪声能力，可以在 FB 下分压 电阻上并联一个约 100pF 左右的电容。 4 过温调节功能 BP2338 具有过热调节功能，在驱动电源过热时逐 渐减小输出电流，从而控制输出功率和温升，使 电源温度保持在设定值，以提高系统的可靠性。 芯片内部设定过热调节温度点为 140℃。 5 保护功能 BP2338 内置多重保护功能，保证了系统可靠性。 当 LED 开路时，输出电压逐渐上升，FB 引脚可以 在功率管关断时检测到输出电压。 当 FB 升高到 OVP 保护阈值时，会触发保护逻辑并停止开关工作。 系统进入保护状态后，内部高压电路停止对 VCC 充 电， VCC 电压开始下降， 当 VCC 到达欠压保护阈值时， 系统将重启。同时系统不断的检测系统状态，如 果故障解除，系统会重新开始正常工作。 当 LED 短路时，系统工作在 7kHz 低频，以减小短 路功耗。 当变压器饱和时，CS 峰值电压将会比较高。当 CS 电压上升到内部限制值（1.5V）时，该开关周期 马上停止。此逐周期限流功能可以保护功率 MOS 管、功率电感和输出续流二极管。 6 PCB 设计 在设计 BP2338 PCB 板时，需要注意以下事项： 旁路电容

Whether you play in a stadium, bar, or rehearsal space, they all have one thing in common: the aC power is supplied from your local utility. What’s worse is that the “power factor” supplied from your building’s aC outlet is typically poor, thanks to increasingly over taxed power lines and raised line impedance. in fact, the quality of aC power has been so poor for so long, most musicians have no idea how great their amplifiers could really sound. When the AC power factor is poor, amplifiers sound muddy because their power supplies can’t deliver when pushed. the scream and cry from a guitar loses bite and harmonics, bass guitars lose their punch and weight, keyboards sound nasally, losing clarity, attack, and extension.furman’s Power factor Pro addresses this issue - allowing your amplifier to sound its best while protecting it at the same time. desCriPtionthe Power factor Pro’s “Clear tone technology tM” actually lowers the aC line impedance supplied by your wall outlet, while storing energy for peak current demands. in fact, there are over 45 amps of instantaneous current reserve in the Power factor Pro. additionally, “linear filtering technology tM” dramatically lowers aC line noise to unprecedented levels in the critical audio frequency band. What does this mean? Just plug in your current-starved amplifier, crankup the volume, and listen to the dynamics,harmonics, and clarity you’ve been missing!additionally, the Power factor Pro is the most comprehensive power conditioner ever created for the serious musician. furman’s series Multi-stage Protection Plus (sMP+) guards your equipment from voltage spikes that can damage your amplifier or other connected equipment.furman’s sMP+ features unparalleled clamping voltage. While other designs offer clamping voltages that are well above 330Vpk, furman’s sMP+ clamps at 188Vpk (133 VaC rMs) even when tested with multiple 6000Vpk - 3000 amp surges! and, our pro level over-voltage auto shutdown circuit assures you will never see your prized amplifier go up in flames due to a sustained voltage overload.the Pf-Pro has a generous 12 amp r.M.s. capacity, a convenient 20 segment aC voltmeter, a detachable-locking aC cord,and (4) aC outlets, all contained in a small convenient, floor standing package. The PF-Pro r has the same features except its cordis not detachable and it has (8) rear outlets and (1) front panel outlet. it also featuresa BnC connector on the rear panel to allow attachment of any standard gooseneck lamp (such as furman’s model Gn-i or Gn-led) to illuminate the rear of your rack.s a f e t Y i n f o r M at i o nto obtain best results from your furman Power factor Pro Power Conditioner, please be sure to read this manual carefully before using.WA R N I N G:to reduce the risk of electrical shock, do not expose this equipment to rainor moisture. dangerous high voltages are present inside the enclosure. do not removethe covers. Refer servicing to qualifiedpersonnel only. The lightning flash with an arrowhead symbol, is intended to alert the userto the presence of un-insulated dangerous voltage within the product’s enclosure that maybe of sufficient magnitude to constitute a risk of electric shock.i M P o r ta n t s a f e t Yi n s t r u C t i o n s(Please read prior to installation)1. Please read and observe all safety and operating instructions before installingyour Power factor Pro unit. retain these instructions for future reference.2. Your Power factor Pro unit should not beused near water – for example, near a bathtub, washbowl, kitchen sink, laundry tub, in a wet basement, near a swimming pool, etc.3. do not place your Power factor Pro unitnear heat sources such as radiators, heat registers, stoves, or other appliances that produce heat.4. the Power factor Pro should only be connected to a 120 VaC, 60Hz, 15 amp (“e” version - 220 VaC, 10 amp) grounded electrical outlet. do not defeat the ground or change polarization of the power plug.5. Pay particular attention to the condition ofthe cords and cables at the plugs. to preventrisk of fire or injury, damaged cords and cables should be replaced immediately.26. Clean your Power factor Pro unit witha damp cloth only. do not use solvents or abrasive cleaners. never pour liquid on or into the unit.7. Your Power factor Pro unit should be serviced by qualified service personnel when:• the power supply cord or the plug has been frayed or cut.• Objects have fallen or liquid has spilled into the unit.• the unit has been exposed to rain or other moisture.• the unit does not appear to operate normally.• the “Protection oK” indicator is not lit.• the unit has been dropped, or the enclosure has been seriously damaged.8. Your Power factor Pro unit requires that a safety ground be present for proper operation. Any attempt to operate the unit withouta safety ground is considered improper operation and could invalidate the warranty.9. do not attempt to service your Power factor Pro unit beyond what is described in this manual. all other servicing should be referred to qualified service personnel.f e a t u r e sthe Power factor Pro has a master switch for the rear outlets that glows red when the power is on. The circuit breaker is located adjacent to the power switch for the Pf-Pro and on the rear panel for the Pf-Pro r. it can be quickly and easily reset should the unit be overloaded. the Pf-Pro also features a detachable 10 foot, 14 gauge heavy-duty power cable. the Power factor Pro, offers a 20 segment led bar-graph meter that displays incoming voltage between 90 and 128 volts in 2-volt increments. the normal range voltages are indicated in green, with moderately and extremely high or low voltages in yellow and red respectively. the voltmeter’s accuracyis ±2 volts. it can easily be recalibrated, if necessary.the Pf-Pro r features a rear rack BnC socket which will accept any 12 VaC (0.5a) gooseneck lamp assembly, (such as the furman Gn-led or Gn-i). simply slide the BnC plug over the socket and rotate clockwise until the connector snaps into the locked position. the rear rack lamp can be powered on or off with the rear light power switch located on the far left of the front panel.o P e r at i o nmulti-Segment leD Voltmeter:this three-color, 20-led bargraph is an accurate, self checking aC voltmeter that continually measures input voltages. the meter reads from 90 to 128 volts in 2 volt steps (Power factor Pro e: 180 to 256 volts, in 4 volt steps). the normal range voltages are indicated in green, with moderate and extremely high or low voltages in yellow and red respectively. the voltmeter provides three special flashing patterns to indicate abnormal conditions.(1) on initial turn on, the voltmeter willscan for smart chip integrity.(2) if only the single leftmost (beneaththe 90V mark) LED flashes, the inputvoltage is marginally low.3(3) if all of the leds on the voltmeterflash, the input voltage is marginallyhigh. Power to the Power factorPro’s outlets will remain on unless theincoming voltage rises above theextreme Voltage shutdown (eVs)cut-off voltage (135 - 140 volts).the Power factor Pro’s voltmeter has a basic accuracy of plus or minus two volts, and extreme cold or heat may cause an additional one volt of error (four volts and two volts for Power factor Pro e).NOTE: although the Power factor correction will more than compensate for peak current demands, the Power factor Pro does not compensate for sustained high or low line voltage. if you derive power from generators, travel internationally, or are in an area proneto extreme brownouts, you may benefit from the use of one of furman’s aC line Voltage regulators.on/off rocker Switch:this 15 amp capacity power switch is specifically designed to stand up to the enormous high inrush current demands placed by many instrument amplifiers. Additionally, the semi-transparent rocker lights when switched to the “on” position.extreme Voltage Shutdown (eVS) Indicator:this led is normally off. it monitors a hazard unfortunately common in the entertainment industry: wiring faults – for example, accidental connection to 220VaC where 120VaC is expected, or an open neutral from a 208 or240VaC feed. the Power factor Pro’s sMP+ circuit senses voltages that are so high that operation would be impossible and shuts the power down before damage can occur. upon initially applying power to these units, the extreme Voltage indicator led will be lit if the input voltage is above the extreme voltage cutoff, and power will not be applied to theunit’s outlets. if the unit has been operatingwith an acceptable input voltage and then that voltage goes above 135V, it will shut off powerto the outlet and the extreme Voltage led will light.note: if the mains power is above the highcutoff voltage and has caused the unit toremove power from its outlets, it cannot restore power without the operator manually turningthe unit off, then on again. avoid turning theunit back on without checking the source of the problem first, and perhaps changing the AC source.4Mains Vltg.

LMP8278QFebruary 9, 2012High Common Mode, 14 x Gain, Precision Current Sensing AmplifierGeneral DescriptionThe LMP8278 is a fixed 14x gain precision current sense amplifier. The part amplifies and filters small differential signals in the presence of high common mode voltages. The part operates from a single 5V supply voltage. With an input common mode voltage range from -2V to +28V the gain is very precise (±0.5%). The part can handle common mode voltages in the range -2V to +40V with relaxed specifications. The LMP8278 is a member of the Linear Monolithic Precision (LMP®) family and is ideal for unidirectional current sensing applications. The parameter values that are shown in the Electrical Characteristics table are 100% tested and all bold values are also 100% tested over temperature, unless other-wise noted.The part has a precise gain of 14x which is adequate in most targeted applications to drive an ADC to its full scale value. The fixed gain is achieved in two separate stages, a pream-plifier with a gain of 7x and an output stage buffer amplifier with a gain of 2x. The connection between the two stages of the signal path is brought out on two pins to enable the pos-sibility to create an additional filter network around the output buffer amplifier. These pins can also be used for alternative configurations with different gain as described in the applica-tions section.The LMP8278Q incorporates enhanced manufacturing and support processes for the automotive market, including defect detection methodologies.

The LMP8278 is a member of the LMP family and is ideal for unidirectional current sensing applications. Because of its proprietary level-shift input stage the LMP8278 achieves very low offset, very low thermal offset drift, and very high CMRR. The LMP8278 amplifies and filters small differential signals in the presence of high common mode voltages.The LMP8278 uses level shift resistors at the inputs. Because of these resistors, the LMP8278 can easily withstand very large differential input voltages that may exist in fault condi-tions where some other less protected current sense ampli-fiers might sustain permanent damage.The LMP8278 is available in an 8–Pin MSOP package. For the MSOP package, the pitch of the solder pads is too narrowfor reliable use at higher voltages (VCM > 25V). Therefore, itis strongly advised to add a conformal coating on the PCB assembled with the LMP8278 in MSOP package. PERFORMANCE GUARANTIESTo guaranty the high performance of the LMP8278, minimum and maximum values shown in the Electrical Characteristics table of this datasheet are 100% tested and all bold limits are also 100% tested over temperature, unless otherwise noted.THEORY OF OPERATIONThe schematic shown in Figure 1 gives a schematic repre-sentation of the internal operation of the LMP8278.The signal on the input pins is typically a small differential voltage across a current sensing shunt resistor. The input signal may appear at a high common mode voltage. The input signals are accessed through two input resistors. The propri-etary level shift circuit brings the common mode voltage be-hind the input resistors within the supply rails. Subsequently, the signal is gained up by a factor of 7 and brought out on the A1 pin through a trimmed 100 kΩ resistor. In the application, additional gain adjustment or filtering components can be added between the A1 and A2 pins as will be explained in subsequent sections. The signal on the A2 pin is further am-plified by a factor of 2 and brought out on the OUT pin.30088105FIGURE 1. Theory of Operation LMP8278QADDITIONAL SECOND ORDER LOW PASS FILTERThe bandwidth of the output buffer can be reduced by addinga capacitor on the A1 pin to create a first order low pass filterwith a time constant determined by the 100 kΩ internal resis-tor and the external filter capacitor.It is also possible to create an additional second order Sallen-Key low pass filter, as illustrated in Figure 2, by adding exter-nal components R2, C1and C2. Together with the internal 100kΩ resistor R1, this circuit creates a second order low-passfilter characteristic.When the corner frequency of the additional filter is muchlower than 90 kHz, the transfer function of the described am-plifier can be written as:Where K1equals the gain of the preamplifier and K2that ofthe buffer amplifier.The above equation can be written in the normalized frequen-cy response for a 2nd order low pass filter:The cutt-off frequency ωoin rad/sec (divide by 2π to get thecut-off frequency in Hz) is given by:And the quality factor of the filter is given by:With K2>1x, the above equation results in:For any filter gain K > 1x, the design procedure can be verysimple if the two capacitors are chosen in a certain ratio.In this case, given the predetermined value of R1 = 100 kΩ(the internal resistor), the quality factor is set solely by thevalue of the resistor R2.R2can be calculated based on the desired value of Q as thefirst step of the design procedure with the following equation:For the gain of 2 for the LMP8278 this results in:30088155FIGURE 2. Second Order Low Pass Filter10LMP8278QFor instance, the value of Q can be set to 0.5√2 to create aButterworth response, to 1/√3 to create a Bessel response,or to 0.5 to create a critically damped response. Once thevalue of R2has been found, the second and last step of thedesign procedure is to calculate the required value of C to givethe desired low-pass cut-off frequency using:Which for the gain=2 will give:For C2the value is calculated with:Or, for a gain=2, C2=C1Note that the frequency response achieved using this proce-dure will only be accurate if the cut-off frequency of the secondorder filter is much smaller than the intrinsic 90 kHz low-passresponse. In other words, choose the frequency response ofthe circuit such that the internal poles of the LMP8278 do notaffect the external second order filter.For a desired Q = 0.707 and a cut off frequency = 3 kHz, thiswill result in rounded values for R2= 200 kΩ, C1:C2= 390 pF.GAIN ADJUSTMENTThe gain of the LMP8278 is 14; however, this gain can beadjusted as the signal path in between the two internal am-plifiers is available on the external pins.Reduce GainFigure 3 shows the configuration that can be used to reducethe gain of the LMP8278.Rrcreates a resistive divider together with the internal100 kΩ resistor such that the reduced gain Grbecomes:Given a desired value of the reduced gain Gr, using this equa-tion the required value for Rrcan be calculated with:Increase GainFigure 4 shows the configuration that can be used to increasethe gain of the LMP8278.Ricreates positive feedback from the output pin to the inputof the buffer amplifier. The positive feedback increases thegain. The increased gain Gibecomes:From this equation, for a desired value of the gain, the re-quired value of Rican be calculated with:It should be noted from the equation for the gain Githat forlarge gains Riapproaches 100 kΩ. In this case, the denomi-nator in the equation becomes close to zero. In practice, forlarge gains the denominator will be determined by tolerancesin the values of the external resistor Riand the internal100 kΩ resistor. In this case, the gain becomes very inaccu-rate. If the denominator becomes equal to zero, the systemwill even become unstable. It is recommended to limit the ap-plication of this technique to gain values of 35 or smaller.30088156FIGURE 3. Reduce GainLMP8278Q30088157FIGURE 4. Increase GainPOWER SUPPLY DECOUPLINGIn order to decouple the LMP8278 from AC noise on the pow-er supply, it is recommended to use a 0.1 µF bypass capacitor between the V S and GND pins. This capacitor should be placed as close as possible to the supply pins. In some cases an additional 10 µF bypass capacitor may further reduce the supply noise.DRIVING SWITCHED CAPACITIVE LOADSSome ADCs load their signal source with a sample and hold capacitor. The capacitor may be discharged prior to being connected to the signal source. If the LMP8278 is driving such ADCs the sudden current that should be delivered when the sampling occurs may disturb the output signal. This effect was simulated with the circuit shown in Figure 5 where the output is connected to a capacitor that is driven by a rail to rail square wave.30088160FIGURE 5. Driving Switched Capacitive Load This circuit simulates the switched connection of a discharged capacitor to the LMP8278 output. The resulting V OUT distur-bance signal is shown in Figure 6.The figure can be used to estimate the disturbance that will be caused when driving a switched capacitive load. To mini-mize the error signal introduced by the sampling that occurs on the ADC input, an additional RC filter can be placed in between the LMP8278 and the ADC as illustrated in Figure 7.The external capacitor absorbs the charge that flows when the ADC sampling capacitor is connected. The external ca-pacitor should be much larger than the sample and hold capacitor at the input of the ADC and the RC time constant of the external filter should be such that the speed of the system is not affected.501001502002503001.001.251.501.752.002.252.502.753.00V O U T (V )TIME (ns)10 pF 20 pF30088190FIGURE 6.

Reduce Error When Driving ADCs 12L M P 8278QLOW SIDE CURRENT SENSING APPLICATIONFigure 8 illustrates a low side current sensing application with a low side driver. The power transistor is pulse width modu-lated to control the average current flowing through the in-ductive load which is connected to a relatively high battery voltage. The current through the load is measured across ashunt resistor RSENSE in series with the load. When the powertransistor is on, current flows from the battery through the in-ductive load, the shunt resistor and the power transistor to ground. In this case, the common mode voltage on the shunt is close to ground. When the power transistor is off, current flows through the inductive load, through the shunt resistor and through the freewheeling diode. In this case the common mode voltage on the shunt is at least one diode voltage drop above the battery voltage. Therefore, in this application the common mode voltage on the shunt is varying between a large positive voltage and a relatively low voltage. Because the large common mode voltage range of the LMP8278 and because of the high AC common mode rejection ratio, the LMP8278 is very well suited for this application.30088152FIGURE 8. Low Side Current Sensing ApplicationHIGH SIDE CURRENT SENSING APPLICATIONFigure 9 illustrates the application of the LMP8278 in a high side sensing application. This application is similar to the low side sensing discussed above, except in this application the common mode voltage on the shunt drops below ground when the driver is switched off. Because the common mode voltage range of the LMP8278 extends below the negative rail, the LMP8278 is also very well suited for this application.30088153FIGURE 9. High Side Current Sensing Application LMP8278QRF-PA CONTROL APPLICATIONFigure 10 illustrates how the LMP8278 can be used to monitor current flow in an RF power amplifier control application. The fact that the LMP8278 can measure small voltages at a high common mode voltage outside its own supply range makesthis part a good choice for such an application. The output signal of the LMP8278 is used as an input for the PA con-troller. The PA controller can be used to regulate the output power of the RF-PA by measuring the output amplifier supply current.30088103FIGURE 10.
