General DescriptionThe MAX1963/MAX1976 low-dropout linear regulators operate from a +1.62V to +3.6V supply and deliver a guaranteed 300mA continuous load current with a low 100mV dropout. The high-accuracy (±0.5%) output voltage is preset to an internally trimmed voltage in the +0.75V to +3.0V range. An active-low, open-drain reset output remains asserted for at least 2.2ms (MAX1963)or 70ms (MAX1976) after the output voltage reaches regulation. These devices are offered in 6-pin thin SOT23 and 6-pin 3mm x 3mm thin DFN packages.An internal PMOS pass transistor allows the low supply current to remain independent of load and dropout volt-age, making these devices ideal for portable battery-pow-ered equipment such as personal digital assistants (PDAs), cell phones, cordless phones, and notebook com-puters. Other features include logic-controlled shutdown,short-circuit protection, and thermal-overload protection.ApplicationsNotebook Computers Cellular and PCS Telephones Personal Digital Assistants (PDAs)Hand-Held Computers Digital Cameras PCMCIA Cards CD and MP3 PlayersFeatures♦Low 1.62V Minimum Input Voltage ♦Guaranteed 300mA Output Current ♦±2.5% Accuracy Over Load/Line/Temp ♦Low 100mV Dropout at 300mA Load ♦2.2ms (MAX1963) or 70ms (MAX1976) RESET Output Flag ♦Supply Current Independent of Load and Dropout Voltage ♦Logic-Controlled Shutdown♦Thermal-Overload and Short-Circuit Protection ♦Preset Output Voltages (0.75V to 3.0V)♦Tiny 6-Pin Thin SOT23 Package (<1.1mm High)♦Thin 6-Pin TDFN Package (<0.8mm High)MAX1963/MAX1976Low-Input-Voltage, 300mA LDO Regulatorswith RESET in SOT and TDFN________________________________________________________________Maxim Integrated Products1Ordering Information19-3040; Rev 2; 5/07For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .Pin Configurations*Insert the desired three-digit suffix (see the Selector Guide) into the blanks to complete the part number.

These devices supply loads up to 300mA and are available with preset output voltages from +0.75V to +3.0V. As illustrated in Figure 1,the MAX1963/MAX1976 consist of a reference, an error amplifier, a P-channel pass transistor, an internal feed-back voltage-divider, and a power-good comparator.The reference is connected to the error amplifier, which compares this reference with the feedback voltage and amplifies the difference. If the feedback voltage is lower than the reference voltage, the pass-transistor gate is pulled lower, which allows more current to pass to the output and increases the output voltage. If the feedback voltage is too high, the pass-transistor gate is pulled up, allowing less current to pass to the output.Low-Input-Voltage, 300mA LDO Regulators with RESET in SOT and TDFN 6_______________________________________________________________________________________Pin DescriptionFigure 1. Functional DiagramInternal P-Channel Pass Transistor The MAX1963/MAX1976 feature a 0.33Ω(R DS(ON)) P-channel MOSF ET pass transistor. Unlike similar designs using PNP pass transistors, P-channel MOSFETs require no base drive, which reduces quies-cent current. PNP-based regulators also waste consid-erable current in dropout when the pass transistor saturates and use high base-drive currents under large loads. The MAX1963/MAX1976 do not suffer from these problems and consume only 90µA (typ) of quiescent current under heavy loads, as well as in dropout.Shutdown Pull SHDN low to enter shutdown. During shutdown, the output is disconnected from the input, an internal 1.5kΩresistor pulls OUT to GND, RESET is actively pulled low, and the supply current drops below 1µA.RESET Output The MAX1963/MAX1976 microprocessor (µP) supervisory circuitry asserts a guaranteed logic-low reset during power-up, power-down, and brownout conditions down to +1V. RESET asserts when V OUT is below the reset threshold and remains asserted for at least t RP after V OUT rises above the reset threshold of regulation.Current Limit The MAX1963/MAX1976monitor and control the pass transistor’s gate voltage, limiting the output current to 450mA (min). If the output exceeds I LIM, the MAX1963/ MAX1976 output voltage drops.Thermal-Overload Protection Thermal-overload protection limits total power dissipa-tion in the MAX1963/MAX1976. When the junction tem-perature exceeds T J= +165°C, a thermal sensor turns off the pass transistor, allowing the IC to cool. The ther-mal sensor turns the pass transistor on again after the junction temperature cools by 15°C, resulting in a pulsed output during continuous thermal-overload con-ditions. Thermal-overload protection safeguards the MAX1963/MAX1976 in the event of fault conditions. For continuous operation, do not exceed the absolute maxi-mum junction-temperature rating of T J= +150°C.Operating Region and Power Dissipation The MAX1963/MAX1976 maximum power dissipation depends on the thermal resistance of the IC package and circuit board, the temperature difference between the die junction and ambient air, and the rate of airflow. The power dissipated in the device is P = I OUT✕(V IN-V OUT). The maximum allowed power dissipation is:P MAX= (T J(MAX)- T A) / (θJC+ θCA)between the MAX1963/MAX1976 die junction and the surrounding air, θJC is the thermal resistance of the junction to the case, and θCA is the thermal resistancefrom the case through the PC board, copper traces,and other materials to the surrounding air. F or best heatsinking, expand the copper connected to the exposed paddle or GND.MAX1963/MAX1976Low-Input-Voltage, 300mA LDO Regulatorswith RESET in SOT and TDFN _______________________________________________________________________________________7M A X 1963/M A X 1976The MAX1963/MAX1976 deliver up to 300mA and oper-ate with an input voltage up to +3.6V. However, when using the 6-pin SOT23 version, high output currents can only be sustained when the input-output differential voltage is less than 2V, as shown in Figure 2.The maximum allowed power dissipation for the 6-pin TDFN is 1.951W at T A = +70°C. Figure 3 shows that the maximum input-output differential voltage is not limited by the TDFN package power rating.Applications InformationCapacitor Selection andRegulator StabilityCapacitors are required at the MAX1963/MAX1976input and output for stable operation over the full tem-perature range and with load currents up to 300mA.Connect a 1µF ceramic capacitor between IN and GND and a 4.7µF low-ESR ceramic capacitor between OUT and GND. The input capacitor (C IN ) lowers the source impedance of the input supply. Use larger output capacitors to reduce noise and improve load-transient response, stability, and power-supply rejection.The output capacitor’s equivalent series resistance (ESR) affects stability and output noise. Use output capacitors with an ESR of 30m Ωor less to ensure sta-bility and optimize transient response. Surface-mount ceramic capacitors have very low ESR and are com-monly available in values up to 10µF. Connect C IN and C OUT as close to the MAX1963/MAX1976 as possible to minimize the impact of PC board trace inductance.Noise, PSRR, and Transient ResponseThe MAX1963/MAX1976 are designed to operate with low dropout voltages and low quiescent currents in bat-tery-powered systems while still maintaining good noise, transient response, and AC rejection. See the T ypical Operating Characteristics for a plot of Power-Supply Rejection Ratio (PSRR) versus F requency.When operating from noisy sources, improved supply-noise rejection and transient response can be achieved by increasing the values of the input and output bypass capacitors and through passive filtering techniques.The MAX1963/MAX1976 load-transient response (see the Typical Operating Characteristics ) shows two com-ponents of the output response: a near-zero DC shift from the output impedance due to the load-current change, and the transient response. A typical transientresponse for a step change in the load current from 20mA to 200mA is 20mV. Increasing the output capacitor’s value and decreasing the ESR attenuates the overshoot.Input-Output (Dropout) VoltageA regulator’s minimum input-output voltage difference (dropout voltage) determines the lowest usable supply voltage. In battery-powered systems, this determines the useful end-of-life battery voltage. Because the MAX1963/MAX1976 use a P-channel MOSFET pass tran-sistor, the dropout voltage is a function of drain-to-source on-resistance (R DS(ON) = 0.33Ω) multiplied by the load current (see the Typical Operating Characteristics ).V DROPOUT = V IN - V OUT = 0.33Ω✕I OUTThe MAX1963/MAX1976 ground current reduces to 70µA in dropout.Low-Input-Voltage, 300mA LDO Regulators with RESET in SOT and TDFN 8_______________________________________________________________________________________Chip InformationTRANSISTOR COUNT: 2556PROCESS: BiCMOSSelector Guide(Note: Standard voltage options, shown in bold , are available.Contact the factory for other output voltages between 1.5V and 4.5V.

SmartLine STIW400 Wireless Temperature DI Transmitter Specification 34-SW-03-11, April 2022Model STIW400•Up to 4 channels of inputs for T/C’s or mV.•Up to 2 channels of RTD’s or 3-wire resistance.•Up to 4 channels for discrete input or 2-wireresistance.IntroductionSmartLine Wireless Temperature continues theevolution of Honeywell’s wireless transmitter productoffering and provides the latest critical advancementsto support industrial automation users’ desire to expandwireless use for monitoring and control.With over 14 years of industrial wireless experience,the SmartLine Wireless Temperature builds upon andis compatible with the current XYR 6000 productporfotlio. Similar to the XYR 6000 wireless transmitter,the SmartLine Wireless product line is part of theHoneywell OneWireless™ system and is ISA100 -ready.The SmartLine Wireless Temperature transmitterenables customers to obtain data and createinformation from remote and hazardous measurement locations without the need to run wires, where running wire is cost prohibitive and/or the measurement is in a hazardous location. Without wires, transmitters can be installed and operational in minutes, quickly providing information back to your system.The previous generation transmitters primarily were applied to monitoring applications but experienced users know that Honeywell’s wireless products are as reliable, secure, and safe as their wired counterparts. With this knowledge, users are now looking for wireless transmitters for use in specific control applications.Figure 1 — SmartLine Wireless Temperature DITransmitterSmartLine Wireless introduces a step change in performance and most notably, performance suitable for control. SmartLine Wireless performance is improved in these ways:•Fast ½ second publication rate.•Higher radio range coverage.•More powerful 4dBi integral antenna.•Smarter local display with more localdiagnostics and radio signal and qualityindicators.•More input channels and types than earlier.XYR 6000 Wireless Pressure Transmitter Differential Pressure Models 2SmartLine Wireless Temperature retains the following desirable features from the XYR 6000 product offering:•Mesh or non-mesh configuration within each transmitter.•Generic, off-the-shelf lithium ion battery.•Two “D” size batterie s for longer life.•Choice of over-the-air or local provisioning (network security join key).•Over-the-air firmware upgrade capability.•Unique, encrypted provisionng key delivered from the factory.•Remote and integral antenna options.•24 VDC power option.•Publication rates of 1, 5, 10, or 30 seconds, plus new selections of ½ seconds and 1, 15,30, 60 minutes.•Transmitter range (integral antenna) of 1150’ (350 m) under ideal conditions.The STIW400 is a high-performance Temperature transmitter featuring performance over a wide of temperature configurations and applications.The SmartLine family is also fully tested and compliant with Experion® PKS providing the highest level of compatibility assurance and integration capabilities. SmartLine easily meets the most demanding application needs for Temperature measurement applications. SmartLine Wireless FeaturesLocal and over-the-air provisioning capability:All Honeywell wireless devices feature a secure method to join the local wireless network, also known as provisioning. SmartLine Wireless transmitters feature two methods to provision a transmitter onto the network which are eitherby using a handheld device to locally communicate through the IR interface or remotely using the over-the-air function. The over-the-air function is managed by the OneWireless gateway, Wireless Device Manager (WDM). Over-the-air firmware updates:Once joined as a member of your OneWireless network, the WDM can download new transmitter firmware releases to each SmartLine Wireless transmitter over the wireless network. Locating and accessing the transmitter locally is not required thus saving time and keeping your personnel in safe environments.Mesh and non-mesh capability: All SmartLine Wireless transmitters can be configured to operate in either a mesh network or a star (non-mesh) network. The configuration is specific to each wireless transmitter and thus the network can consist of a mixture of meshing and non-meshing devices. Non-meshing is desirable for deterministic communications which is preferred for control. Transmission power setting:To comply with local and regional requirements, SmartLine Wireless transmitters are set at the factory to the maximum transmission power setting allowed for the country of use.Non-proprietary battery:Sourcing lithium thionyl chloride batteries is much simpler since SmartLine Wireless utilizes commercial off-the-shelf batteries. Please see the list of approved battery manufacturers later in this specification. Batteries are housed in an IS-approved battery compartment making battery changes safe and easy. Backward compatibility:SmartLine Wireless transmitters can join existing OneWireless networks and interoperate with existing XYR 6000 wireless transmitters or otherISA100 Wireless compliant transmitters or networks.OneWireless Network FeaturesThe core of the Honeywell wireless solution is the OneWireless Network which consists a gateway, access point(s), and field routers.The Wireless Device Manager (WDM) serves as the gateway function and in this role, manages the communication from the wireless field devices to the process control application. Typically, the WDM connects logically to the process control network (Level 2 or wireless DMZ). As the wireless network manager, the WDM provides easy access to the entire wireless network through a browser-based user interface. The Honeywell WDM can manage devices communicating over theISA100 Wireless protocol and the Wireless HART protocol.The ability to deploy redundant WDMs improves the reliability ensuring no loss of process data which is a requirement for control applications.The Field Device Access Point (FDAP) serves in two roles in the OneWireless network infrastructure, which are: 1) access point, and 2) field router. As an access point, the FDAP directly connects to the WDM via Ethernet LAN cable. More than one access point is permitted and, when more than one is present, it ensures dual path for communications into the WDM from the field devices. As a field router, the FDAP located in the field would communicate to the FDAP acting as an access point. Using the FDAP as a router is more efficient than using field devices as routers since FDAPs are line powered devices whereas field devices are typically battery powered, and the FDAP offers greater range. The meshing capability of FDAPs allows flexibility in the setup of the wireless network to fit the requirements for wireless network performance, in terms of reliable communications, performance, and future growth. The choice of non-meshing network may be desirable for reduced communication latencies with a FDAP serving as a field router.Wireless Specifications*Actual range will vary depending on antennas, cables and site topography.SpecificationsOperating Conditions1 The Ambient Limits shown are for Ordinary Non-Hazardous locations only.

LED bias currents are matched to 0.3% by the MAX1916’s unique current-matching architecture (Figure 1). Supply current (I EN) is a low 40µA in normal operation and 0.05µA when disabled.The MAX1916 offers several advantages over using ballast resistors, such as improved LED-to-LED bright-ness matching, lower bias variation with supply voltage changes, significantly lower dropout voltage, and in some applications, significantly improved efficiency.The MAX1916 achieves a 200mV dropout with a 9mAload on each output.For circuits requiring only one or two LEDs, leave unused LED outputs unconnected.Enable InputEN powers the input of the MAX1916. Drive EN high(> 2.5V) to enable the device; drive EN low (< 2.2V) to disable the device. When driven high, EN draws 40µAto power the IC. Driving EN low forces LED1, LED2,LED3, and SET into a high-impedance state.MAX1916Figure 1. MAX1916 Simplified Functional Diagram 找MEMORY、二三极管上美光存储M A X 1916Setting the Output Current SET controls the LED bias current. Current flowing into LED1, LED2, and LED3 is 230 times greater than the current flowing into SET. Set the output current as fol-lows:where V SET = 1.215V, V CTRL is an external voltage between 1.8V and 5.5V, and R SET is the resistor con-nected between V CTRL and SET (Figure 1).Applications Information 1)Very Low-Cost, High-Efficiency Solution (Figure 2).A battery (single Li+ or three NiMH cells) powers the LEDs directly. This is the least expensive and most efficient architecture. Due to the high forward voltage of white LEDs (3.3V), the LED brightness may dim slightly at the end of battery life. The MAX1916’s current-regulating architecture and low dropout greatly minimize this effect compared to using simple ballast resistors. The enable function of the MAX1916 turns on and off the LEDs. An exist-ing low-dropout regulator is used as V CTRL .2)Brightness Adjustment Using a DAC (Figure 3). A DAC is used as V CTRL such that the LED brightness may be dynamically adjusted to eliminate factory calibration. A battery (single Li+ or three NiMH cells) or a regulated power source drives the LEDs.3)Existing 5V Supply (Figure 4). Use an existing sys-tem regulator, such as the MAX684, to provide the required LED voltage and provide power to other circuits. Due to the high forward voltage of white LEDs (3.3V), use a 3.6V to 5.5V regulated supply to provide enough voltage headroom such that the LEDs will maintain constant brightness for any bat-tery voltage. Use the existing regulated supply as V CTRL .Chip Information TRANSISTOR COUNT: 220PROCESS: BiCMOS Low-Dropout, Constant-Current Triple White LED Bias SupplyFigure 2.

With a compact design for assigned motor ratings from 0.25 kW to 5.5 kW, M-MAX can offer maximum flexibility. M-MAX also demonstrates how a high level of functionality can be implemented in a simple and user-friendly design. The small and compact book format design also allows a space saving installation. M-MAX is provided with an integrated RFI filter (EMC) and a flexible interface for solving important machine building requirements, for example, the optimization of production and manufacturing processes. It reliably ensures the required motion sequences of the drive motor and thus contributes to operational safety.M-MAX – the “energy optimizer“M-MAX frequency inverters provide an economical solution for several processes in pumping applications. The integrated PI controller and extensive motor-protective functions ensure a high level of operational reliability and allow significant energy savings in the connected process. The lacquered control boards also allow use in highly humid and aggres-sive environments, such as in a sewage treatment plant. The optional MMX-IP21-FS... accessory enables the degree of protection of the M-MAX to be increased to IP21.M-MAX – the “safe operator“Good climatic conditions as well as safe operation in the event of fire (fume removal) are demanding tasks for frequency controlled ventilation systems in buildings. With its internal protective circuits and the automatic restart option (e.g. after a momentary power failure), as well as automatics ynchronization with the running motor (flying restart circuit), the frequency inverters of the M-MAX series ensure the safe operation of fans in air conditioning and smoke control systems.M-MAX – for “dynamic precision“The compact design of the M-MAX saves valuable mounting space in machine building since the RFI filter and the brake chopper are already integrated. Shielded control and motor cable can also be connected with EMC compliance directly to the frequency inverter. The maximum permissible ambient temperature of +50 °C during operation with continuouscurrent and with full overload withstand capability also meets machine building requirements. The performance of the sensorless vector control ensures also a high speed accuracy; even with load deviations and low motor speeds.MMX-COM-PC – the “in-line communicator“The MMX-COM-PC communication module that can be plugged onto the front provides the following without a mains voltage on the frequency inverter (internal battery):Upload and download of all parameters,• Direct link to a PC via USB interface (parameter • assignment),Copying of parameters for series machines or when • exchanging devices.This communication module considerably increases datas ecurity and reduces the time required for commissioning and maintenance.FeaturesIntegrated RFI filter (EMC: C2 and C3 to/EN61800-3)• Dynamic motor control with sensorless vector control or V/f • control (selectable)Integrated keypad and display unit• Electronic reference value potentiometer • Fixed frequencies • PI controller• Integrated brake unit (with MMX34 in sizes 2 and 3)• 6 digital control inputs (24 V DC)• 1 digital output (transistor, 24 V DC, 50 mA)• 2 analog inputs (0...+10 V DC and 0/4.20 mA)• 1 output analog (0/4...20 mA)• Serial interface (RS485 / Modbus RTU)• 2 relays (1x NO, 1x changeover, 230 V AC, 2 A)• International standards (CE, UL, cUL, c-Tick)• Application examplesSpeed control of asynchronous three-phase motors up to • 5.5 kW (400 V)Pump and fan applications in buildings and industrial areas • with quadratic and linear load characteristics.The high speed accuracy (sensorless) allows a whole range • of possible applications in the textile, paper and printing industry, as well as with finishing machines in the metal industry.The compact design with integrated EMC filter offers• maximum flexibility in machine building and saves valuable mounting space.The twofold startup torque and 1.5 overload torque allows • the implementation of applications with demanding speed and torque requirements.Frequency inverters - simple and straightforwardDisplay unitFunction keysSTARTMotor start via keypad(function must be activated)STOPMotor stop via keypad• Acknowledges the display fault message (Reset)• Activates the Startup Wizard (press for 5 s)• OKActivates the selected parameter • Confirm the set value• Parameter group selection (submenu)• BACK/RESETBack in menu.

Supertex inc.AN-H59Application NoteApplication CircuitHigh Voltage DC/DC Converter forSupertex Ultrasound Transmitter DemoboardsBy Afshaneh Brown, Applications Engineer,and Jimes Lei, Applications ManagerIntroductionThe Supertex AN-H59DB1 demoboard is a high voltage DC/DC converter. It can provide up to +90V voltage supply for V PP and -90V for V NN . It also provides +8.0 to +10V voltage supply for V DD , floating power supplies of V NN +8.0 to V NN +10V for V NF and V PP -8.0 to V PP -10V for V PF . The input supply voltage is 12V.The AN-H59DB1 circuitry consists of two high voltage PWM Current-Mode controllers, a DC/DC transformer driver, and three low dropout regulators. The Supertex AN-H59DB1 uses a high-voltage, current mode, PWM controller boost topology to generate +15 to +90V and a high-voltage current mode PWM controller buck-boost topology to generate -15 to -90V power supply voltage for Supertex HV738DB1 and HV748DB1 ultrasound transmitter demoboards.Each of the transmitter demoboards has slightly different operating voltages as summarized below.To accommodate all three demoboards, the AN-H59DB1 demoboard has adjustable V PP , V NN , V DD , V PF and V NF . The purpose of the AN-H59DB1 is to aid in the evaluation of the three transmitter demoboards. The intention of this application note is to provide a general circuit description on how each of the output voltages is generated.The VSUB pin on the HV738DB1 and HV748DB1 can either be connected to the most positive supply voltage on the demoboard, or can be left floating.To power up the AN-H59DB1, ensure that the 3.3V power supply will be powered up first, and then the 12V power supply. The sequences on the HV738DB1 and HV748DB1 took into consideration using the protection diodes on each power line.The circuit is shown in Figure 6, the component placement in Figure 5, and the bill of materials is at the end of thisapplication note.PP The circuit in Figure 1 shows U5, the Supertex high volt -age current mode PWM controller, being used to generate the high voltage power supply for V PP . The maximum output power for V PP was set for 10mA at 90V, which is 900mW. With an input voltage of 12V, a converter frequency of 110 kHz with a 100µH inductor was chosen to provide the de -sired output power.The converter frequency is set by an external resistor, R20, across OSC IN and OSC OUT pins of U5. A 154kΩ resistor will set the frequency to about 110 kHz. R24 is the current sense resistor. 2.2Ω was used to set the maximum peak current limit to about 450mA. An RC filter, R23 and C15, is added between the current sense resistor and the current sense terminal pin 3 of U5. This reduces the leading edge spike on R24 from entering the current sense pin.Inductor L1 is being charged from the 12V input by M3. When M3 turns off, the energy in L1 is discharged into C16, which is the V PP output through D8. The V PP voltage is di-vided down by feedback resistors R25, R26, and R27. The wiper of R26 is connected to pin 14 of U5. The overall con -verter will regulate the voltage on pin 14 to 4.0V. Different V PP output voltages can be obtained by adjusting R26.When the wiper for R26 is set to the top, V PP can be calcu-lated as:where V FB is 4.0VWhen the wiper for R26 is set to the bottom, V PP can be calculated as:By adjusting potentiometer R26, V PP meets the adjustable target range of 15 to parator U6 will turn on LED D7 when the V PP output is out of regulation due to excessive load. During initial power up, C16 will be at 0V. D7 is therefore expected to be on until C16 is charged to the desired regulation voltage.Figure 1: Adjustable V PP Power SupplyV PPGNDV PP = 4.0V x ( 232k + 100k + 14.3k )= 12.1V 100k + 14.3k V PP= V FBx ( R25 + R26 + R27 )R26 + R27V PP = 4.0V x ( 232k + 100k + 14.3k )= 96.9V 14.3kV PP = V FBx ( R25 + R26 + R27 )R27NN The circuit in Figure 2 shows U7, the Supertex high voltage current mode PWM controller, being used to generate the high voltage power supply for V NN . The function of U7 is very similar to what was described in the V PP circuit description for U5. However, in this circuit a negative voltage is gener -ated from a positive input voltage source, therefore requir-ing a buck-boost topology. The maximum output power for V NN was set for -10mA at -90V which is 900mW. With an input voltage of 12V, a converter frequency of 110 kHz with a 100µH inductor was chosen to provide the desired output power.Inductor L2 is being charged from the 12V input by the par-allel combination of M6 and M7. When M6 and M7 turn off, the energy in L2 is discharged into C23, which is the V NNoutput through D10. M6 and M7 are high voltage P-channel MOSFETs. U7 is designed to drive a high voltage N-chan -nel MOSFET. The drive output for U7 therefore needs to be inverted. This is accomplished by M4 and M5.The feedback voltage that U7 detects on pin 14 is +4.0V. The V NN that needs to be sensed is a negative voltage. A cir-cuit is needed to make sure the feedback voltage is positive. This is consists of Q4, Q5, R33, R34, R35, R37, and R38. Q4 becomes a constant current sink set by the V NN voltageand R35. The same current will be flowing through R33 and R34.The voltage on the base of Q5 will be V IN minus the voltage drop across the sum of R33 and R34. By varying R34, the base voltage on Q5 will change. Q5 becomes a constant current source with a value set by its base voltage and R37. The current source of Q5 is going into R38, which creates a positive voltage that is now proportional to the magnitude of V NN .where V BE = 0.6V, V FB = 4.0V.When R34 is set to 100k, V NN is calculated to be:= -4.0VWhen R34 is set to 0k, V NN is calculated to be:= -97.4V By adjusting potentiometer R34, V NN meets the adjustable target range of -15 to parator U8 will turn on LED D9 when the V NN output isout of regulation due to excessive load. During initial power up, C23 will be at 0V. D9 is therefore expected to be on until C23 is charged to the desired regulation voltage.Figure 2: Adjustable V NN Power SupplyVNN-15V to -90V GNDV NN = V BE - ( R35 ) x (V BE + V FB x R37 ), R33 + R34 R38V NN = 0.6V - ( 273k) x (0.6V + 4.0V x 14.7k ) 4.99k + 100k 40.2k V NN = 0.6V - ( 273k ) x (0.6V + 4.0V x 14.7k )4.99k + 0k 40.2kVPF and VNF Circuit DescriptionThe three transmitter demoboards require two floating low voltage supplies, V PF and V NF . The floating supplies need to be adjustable to accommodate the different operating re-quirements for the three different boards. The V PF is 8.0 to 10V below the high voltage V PP positive supply. The V NF is 8.0 to 10V above the high voltage V NN negative supply. The two floating supplies are generated by using two isolated transformers, T1 and T2, and an isolated transformer driver, U1, as shown in Figure 4. Both outputs utilize adjustable low dropout linear regulators, U2 and U3, as shown in Figure 3. U2 and U3 are both Linear Technology LT1521, which has a reference voltage of 3.75V on the ADJ pin. For V PF , resistors R6, R7, and R8 set the output V PF voltage. R7 is a potentiom -eter for adjusting V PF . V PF can be calculated with the following equation:When R7 is set to 20kΩ, V PF becomes:When R7 is set to 0Ω, V PF becomes:Please note that the OUT pin on U2 is referenced to V PP , thereby setting V PF to be 8.0 to 10V below V PP . V NF can also be calculated in a similar manner using resistors R12, R13, and R14. Please note that the GND pin on U3 is referenced to V NN thereby setting V NF to be 8.0 to 10V above V NN .LED indicators, D5 and D11, start to turn on when the input current to U2 and U3 reaches an arbitrary value of 40mA. This is set by Q1 and R3 for V PF and Q2 and R9 for V NF . The input current can be calculated with the following equation: Input current = V EB = 0.5V = 41.3mA R 12.1Ω50mA current limits are added to protect against output shorts. The current limiter is consists of a depletion-mode MOSFET and a series source resistor. The resistor sets the current limit and can be estimated with the following equa -tion:R SERIES = V TH x ( √I LIM / I DSS - 1) where, I LIMV TH = pinch-off voltage for M1 and M2: -2.5V I LIM = desired current limit: 50mAI DSS = saturation current for M1 and M2: 1.1A R SERIES = 39.3Ω. A 40.2Ω resistor was used.Figure 3: Adjustable V PF and V NF Power SupplyV VNFVFPV PF = 3.75V x ( 45.3k + 20k + 24.9k )= 7.53V 20k + 24.9kV PF = 3.75V x ( 45.3k + 0k + 24.9k )= 10.6V 0 +24.9kV PF= V ADJx ( R6 + R7 + R8 )R7 + R8V DD Circuit DescriptionThe V DD output voltage utilizes an adjustable low dropout lin -ear regulator, U4 LT1521, as shown in Figure 4. The desiredadjustable output voltage range is 8.0 to 10V to accommo-date the different operating V DD voltages for the three differ-ent transmitter demoboards.The LT1521 has a reference voltage of 3.75V on the adj pin. Resistors R17, R18, and R19 set the output V DD voltage. R18 is a potentiometer for adjusting V DD . V DD can be calcu-lated with the following equation:When R18 is set to 20kΩ, V DD becomes:When R18 is set to 0Ω, V DD becomes:An LED indicator, D6, is included in case of excessive input,I IN, current. D6 is starts to turn on when the input currentreaches an arbitrary value of 20mA. This is set by Q3 and R15. When the emitter-base junction of Q3 is forward biased (0.5V), Q3 will start to turn on, thereby forward biasing D6.The I IN value to turn D6 on can be calculated with the follow -ing equation: I IN = V EB = 0.5V= 20.6mAR1524.3Ω 3.3V Input TerminalThe AN-H59DB1 has a 3.3V input terminal that is directly connected to the output terminal, V CC . There is no circuitry on this board that uses the 3.3V supply. It is only there as a convenient connection to the 8-pin header. V CC is the logic supply voltage for HV738DB1 and HV748DB1 and can oper-ate from 1.2 to 5V. However, most users will operate V CC at either 3.0 or 3.3V.Input and Output PowerThe output voltages from the AH-H59DB1 are all generated from the 12V input line. With no load on the outputs, the measured input current was about 70mA. This input current can vary from board to board due to variations in the isolated transformer.The maximum output power is:P OUT(MAX) = P VPP(MAX) + P VNN(MAX) + P VPF(MAX) + P VNF(MAX) + P VDD(MAX)P OUT(MAX) = 0.9W + 0.9W + 0.4W + 0.4W + 0.2W P OUT(MAX) = 2.8WUnder this condition, the 12V input current was measured to be 340mA. Input power is therefore 4.08W. This gives an approximate overall efficiency of 69% at full load.Figure 4: Adjustable V DD Power SupplyV IN = 12VVDD+8.0 to 10V GNDV DD = 3.75V x ( 45.3k + 20k + 24.9k )= 7.53V20k + 24.9kV DD = 3.75V x ( 45.3k + 0k + 24.9k )= 10.6V 0 + 24.9k V DD = V ADJ x ( R17 + R18 + R19 )R18 + R19VPF and VNF Output CurrentThe AN-H59DB1 can supply more than 40mA of current for the V PF and V NF outputs. The I NF and I PF input currents for the HV738 or the HV748 can be found in their respective datasheet but are summarized below:This is for continuous 5.0 MHz operation. For ultrasound, thehigh voltage transmitter is operating at very low duty cycles; 1% or lower. At a 1% duty cycle, the average current is ex -pected to be a 100 times lower. The 40mA output current ca -pability on the AN-H59DB1 is more than sufficient to power up the HV738 or the HV748.ConclusionThe main purpose of AN-H59DB1 power supply demoboard is to help the evaluation of the Supertex HV738DB1 and HV748DB1 demoboards by reducing the number of power supplies needed. The AN-H59DB1 was designed to operate from a single 12V input which should be commonly available in any engineering laboratory.The five on-board LEDs allow the user to quickly determine whether there is an overload condition on each of the supplylines. The five potentiometers allow the user to easily adjust each supply to meet their particular needs.Figure 5: AN-H59 Component PlacementFigure 6: AN-H59 Circuit SchematicVPPVPFVNFSupertex inc. does not recommend the use of its products in life support applications, and will not knowingly sell them for use in such applications unless it receives an adequate “product liability indemnification insurance agreement.” Supertex inc. does not assume responsibility for use of devices described, and limits its liability to the replacement of the devices determined defective due to workmanship.

MEMORY存储芯片MAX1626ESA+T中文规格书
General DescriptionThe MAX1626/MAX1627 step-down DC-DC controllersoperate over a 2.6V to 16.5V input voltage range. Thecontrollers deliver load current from 1mA to more than2A. The MAX1626 has pin-selectable 3.3V and 5V out-puts. The MAX1627 supports adjustable outputs from1.3V to 16V.A unique current-limited, pulse-frequency-modulation(PFM) control scheme operates up to 100% duty cycle,resulting in very low dropout voltage. This controlscheme eliminates minimum load requirements andreduces supply current under light loads to 90µA(versus 2mA to 10mA for common pulse-width modula-tion controllers).The devices are available in a 8-pin SOIC package(-40°C to +85°C) and dice (0°C to +70°C).Applications•5V to 3.3V Green PC Applications•Battery-Powered Applications•Handheld Computers•High-Efficiency Step-Down Regulation•Low-Cost Notebook Computer Supplies•Minimum Component DC-DC Converters•PCMCIA Power Supplies•PDAs and Other Handheld Devices•Portable TerminalsBenefits and Features •Reduce External Components and Total Cost •300KHz PWM Switching Reduces Component Size •Tiny Surface-Mount Inductor •Reduce Power Dissipation •> 90% Efficiency from 3mA to 2A Loads •Low Dropout Voltage •100% Maximum Duty Cycle •Reduce Number of DC-DC Controllers to Stock •Wide 2.6V to 16.5V Input Voltage Options •Selectable 3.3V and 5V or Adjustable 1.3V to 16V Output Voltage Options •Reduce System Power Consumption •90µA Max Quiescent Current •1µA Max Shutdown Current •Operates Reliably in Adverse Environment •Soft-Start Limits Startup Current •Current-Limited Control Scheme •Increase Design Flexibility •External P-Channel MOSFET Allows Output Power of > 12.5WPin ConfigurationTypical Operating Circuit 19-1075; Rev 1; 5/15找MEMORY 、二三极管上美光存储MAX1626/MAX16275V/3.3V or Adjustable,100% Duty-Cycle, High-Efficiency,Step-Down DC-DC Controllers Maxim Integrated | 2Electrical CharacteristicsStresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device.

MAX764中文资料
电路一电路二芯片功能介绍：MAX764/765/766是美信公司生产反极性开关稳压器，这类稳压器在过负载时具有高效率，因为它是脉冲调制，所以使用时它的电路消耗低于120uA.如电路一所示，三个型号输出电压不同，MAX764输出为-5V，MAX765输出为-12V，MAX766输出为-15V，可以根据要求选择芯片的型号，因为课题要求变化为-12V，所以，如果选择电路一的话就选择MAX765；电路二为根据两个外部电阻R1和R2调节输出电压，其中R1为固定电阻，R2为可调电阻，具体的选择方法后面会在后面器件选择上介绍，输出电压可以从-1V到-16V调节，因此也可以满足课题的要求。
由于这类IC是脉冲调制，它有很高的开关频率（300KHZ），这个元件能够使用很小的外部贴片元件，并且不需要考虑电磁干扰。
它的内部电源能够驱动大功率的MOS管（最大到5W）,它的封装分为DIP和SO两种。
本课题选择的是8个管脚的DIP封装，1管脚是电压的输出端，此管脚与GND之间并联一个电解电容C4，用于减小输出电压的纹波，由于输出是负电压，所以电解电容的正极端与GND相连，另一端与1引脚相连；2管脚是反馈输入脚，将此引脚与4管脚（ref）相连，使用内部电压分压作为输出，为使输出电压可调，也可以使用外部分压器；3管脚选通端，高电平关闭输入，SHDN为高电平时，这部分处于闭锁状态，此时电流小于5μA.接地时正常工作，所以一般直接与GND相连；4管脚，输出1.5v的参考电压，以提供100uA的负载电流，通过0.1uF旁路电容（C3）接地；5管脚，接地端；6、7管脚，输入正电源，两管脚需要连在一起，在距V+和GND尽可能尽的地方放置0.1uf输入旁路电容（C2）;8管脚，吸收内部P通道功率的MOS管，峰值电流限制在0.75A。
由于该芯片能够输出最大电流为250mA,所以，当传送大的输出电流时，max765运行在连续传导模式，在这个模式下，电流常常流入电感，控制电路适应周期开关频率循环，并且这种循环比开关电容更有优势，这种模式能够提供优越的负载响应和高效率。

Foreign objects left on cooktop may cause damage to the burner and/or get hot. Cookware left oncooktop may get hot.• Cooking with cast iron grill pans is not recommended. Because cast iron cookwareheats so quickly, cast iron grill pans may overheat, causing the induction burner to automatically turn off.• Different manufacturers of cast iron cookware produce pans of varying thicknesses.This will cause some to heat more quickly than others, making them more likelyto cause the unit to automatically shut off. You may need to adjust your cast ironcooking methods based on your specific pan.• Do not use the Hestan Cue system if any part is damaged or broken. Cooking on a glass cooktop that is cracked or broken could introduce many hazards, including but not limited to allowing flammable liquids and materials to enter the electrical area and result in fire and injury. Regularly inspect the system for damage.• Avoid scratching the glass cooktop. Moving or sliding cookware across the glasssurface may result in scratching. Scratching may also be caused by specific kindsof cooking instruments, cast iron cookware, damaged cookware, or by using other foreign objects or materials on the cooktop.• Never place metal objects other than suitable cookware on the induction burner.Metal objects placed on the burner may get hot and create a safety hazard.• Do not wear or place metal objects close to the burner, such as rings, jewelry, watches, etc. Metal objects in close proximity to the induction burner could get hot.• Keep magnetically sensitive objects, such as credit cards and bank cards, away from the burner.• Do not clean burner while in use or while still hot. Hot steam and/or toxic gases can be released when attempting to clean cooktop while it is hot.Unsuitable Cookware: DO NOT USESelecting a LocationThe Hestan Cue Smart Cooking System is designed for indoor use only.

General DescriptionThe MAX1963/MAX1976 low-dropout linear regulators operate from a +1.62V to +3.6V supply and deliver a guaranteed 300mA continuous load current with a low 100mV dropout. The high-accuracy (±0.5%) output voltage is preset to an internally trimmed voltage in the +0.75V to +3.0V range. An active-low, open-drain reset output remains asserted for at least 2.2ms (MAX1963)or 70ms (MAX1976) after the output voltage reaches regulation. These devices are offered in 6-pin thin SOT23 and 6-pin 3mm x 3mm thin DFN packages.An internal PMOS pass transistor allows the low supply current to remain independent of load and dropout volt-age, making these devices ideal for portable battery-pow-ered equipment such as personal digital assistants (PDAs), cell phones, cordless phones, and notebook com-puters. Other features include logic-controlled shutdown,short-circuit protection, and thermal-overload protection.ApplicationsNotebook Computers Cellular and PCS Telephones Personal Digital Assistants (PDAs)Hand-Held Computers Digital Cameras PCMCIA Cards CD and MP3 PlayersFeatures♦Low 1.62V Minimum Input Voltage ♦Guaranteed 300mA Output Current ♦±2.5% Accuracy Over Load/Line/Temp ♦Low 100mV Dropout at 300mA Load ♦2.2ms (MAX1963) or 70ms (MAX1976) RESET Output Flag ♦Supply Current Independent of Load and Dropout Voltage ♦Logic-Controlled Shutdown♦Thermal-Overload and Short-Circuit Protection ♦Preset Output Voltages (0.75V to 3.0V)♦Tiny 6-Pin Thin SOT23 Package (<1.1mm High)♦Thin 6-Pin TDFN Package (<0.8mm High)MAX1963/MAX1976Low-Input-Voltage, 300mA LDO Regulatorswith RESET in SOT and TDFN________________________________________________________________Maxim Integrated Products1Ordering Information19-3040; Rev 2; 5/07For pricing, delivery, and ordering information,please contact Maxim/Dallas Direct!at 1-888-629-4642, or visit Maxim’s website at .Pin Configurations*Insert the desired three-digit suffix (see the Selector Guide) into the blanks to complete the part number.

These devices supply loads up to 300mA and are available with preset output voltages from +0.75V to +3.0V. As illustrated in Figure 1,the MAX1963/MAX1976 consist of a reference, an error amplifier, a P-channel pass transistor, an internal feed-back voltage-divider, and a power-good comparator.The reference is connected to the error amplifier, which compares this reference with the feedback voltage and amplifies the difference. If the feedback voltage is lower than the reference voltage, the pass-transistor gate is pulled lower, which allows more current to pass to the output and increases the output voltage. If the feedback voltage is too high, the pass-transistor gate is pulled up, allowing less current to pass to the output.Low-Input-Voltage, 300mA LDO Regulators with RESET in SOT and TDFN 6_______________________________________________________________________________________Pin DescriptionFigure 1. Functional DiagramInternal P-Channel Pass Transistor The MAX1963/MAX1976 feature a 0.33Ω(R DS(ON)) P-channel MOSF ET pass transistor. Unlike similar designs using PNP pass transistors, P-channel MOSFETs require no base drive, which reduces quies-cent current. PNP-based regulators also waste consid-erable current in dropout when the pass transistor saturates and use high base-drive currents under large loads. The MAX1963/MAX1976 do not suffer from these problems and consume only 90µA (typ) of quiescent current under heavy loads, as well as in dropout.Shutdown Pull SHDN low to enter shutdown. During shutdown, the output is disconnected from the input, an internal 1.5kΩresistor pulls OUT to GND, RESET is actively pulled low, and the supply current drops below 1µA.RESET Output The MAX1963/MAX1976 microprocessor (µP) supervisory circuitry asserts a guaranteed logic-low reset during power-up, power-down, and brownout conditions down to +1V. RESET asserts when V OUT is below the reset threshold and remains asserted for at least t RP after V OUT rises above the reset threshold of regulation.Current Limit The MAX1963/MAX1976monitor and control the pass transistor’s gate voltage, limiting the output current to 450mA (min). If the output exceeds I LIM, the MAX1963/ MAX1976 output voltage drops.Thermal-Overload Protection Thermal-overload protection limits total power dissipa-tion in the MAX1963/MAX1976. When the junction tem-perature exceeds T J= +165°C, a thermal sensor turns off the pass transistor, allowing the IC to cool. The ther-mal sensor turns the pass transistor on again after the junction temperature cools by 15°C, resulting in a pulsed output during continuous thermal-overload con-ditions. Thermal-overload protection safeguards the MAX1963/MAX1976 in the event of fault conditions. For continuous operation, do not exceed the absolute maxi-mum junction-temperature rating of T J= +150°C.Operating Region and Power Dissipation The MAX1963/MAX1976 maximum power dissipation depends on the thermal resistance of the IC package and circuit board, the temperature difference between the die junction and ambient air, and the rate of airflow. The power dissipated in the device is P = I OUT✕(V IN-V OUT). The maximum allowed power dissipation is:P MAX= (T J(MAX)- T A) / (θJC+ θCA)between the MAX1963/MAX1976 die junction and the surrounding air, θJC is the thermal resistance of the junction to the case, and θCA is the thermal resistancefrom the case through the PC board, copper traces,and other materials to the surrounding air. F or best heatsinking, expand the copper connected to the exposed paddle or GND.MAX1963/MAX1976Low-Input-Voltage, 300mA LDO Regulatorswith RESET in SOT and TDFN _______________________________________________________________________________________7M A X 1963/M A X 1976The MAX1963/MAX1976 deliver up to 300mA and oper-ate with an input voltage up to +3.6V. However, when using the 6-pin SOT23 version, high output currents can only be sustained when the input-output differential voltage is less than 2V, as shown in Figure 2.The maximum allowed power dissipation for the 6-pin TDFN is 1.951W at T A = +70°C. Figure 3 shows that the maximum input-output differential voltage is not limited by the TDFN package power rating.Applications InformationCapacitor Selection andRegulator StabilityCapacitors are required at the MAX1963/MAX1976input and output for stable operation over the full tem-perature range and with load currents up to 300mA.Connect a 1µF ceramic capacitor between IN and GND and a 4.7µF low-ESR ceramic capacitor between OUT and GND. The input capacitor (C IN ) lowers the source impedance of the input supply. Use larger output capacitors to reduce noise and improve load-transient response, stability, and power-supply rejection.The output capacitor’s equivalent series resistance (ESR) affects stability and output noise. Use output capacitors with an ESR of 30m Ωor less to ensure sta-bility and optimize transient response. Surface-mount ceramic capacitors have very low ESR and are com-monly available in values up to 10µF. Connect C IN and C OUT as close to the MAX1963/MAX1976 as possible to minimize the impact of PC board trace inductance.Noise, PSRR, and Transient ResponseThe MAX1963/MAX1976 are designed to operate with low dropout voltages and low quiescent currents in bat-tery-powered systems while still maintaining good noise, transient response, and AC rejection. See the T ypical Operating Characteristics for a plot of Power-Supply Rejection Ratio (PSRR) versus F requency.When operating from noisy sources, improved supply-noise rejection and transient response can be achieved by increasing the values of the input and output bypass capacitors and through passive filtering techniques.The MAX1963/MAX1976 load-transient response (see the Typical Operating Characteristics ) shows two com-ponents of the output response: a near-zero DC shift from the output impedance due to the load-current change, and the transient response. A typical transientresponse for a step change in the load current from 20mA to 200mA is 20mV. Increasing the output capacitor’s value and decreasing the ESR attenuates the overshoot.Input-Output (Dropout) VoltageA regulator’s minimum input-output voltage difference (dropout voltage) determines the lowest usable supply voltage. In battery-powered systems, this determines the useful end-of-life battery voltage. Because the MAX1963/MAX1976 use a P-channel MOSFET pass tran-sistor, the dropout voltage is a function of drain-to-source on-resistance (R DS(ON) = 0.33Ω) multiplied by the load current (see the Typical Operating Characteristics ).V DROPOUT = V IN - V OUT = 0.33Ω✕I OUTThe MAX1963/MAX1976 ground current reduces to 70µA in dropout.Low-Input-Voltage, 300mA LDO Regulators with RESET in SOT and TDFN 8_______________________________________________________________________________________Chip InformationTRANSISTOR COUNT: 2556PROCESS: BiCMOSSelector Guide(Note: Standard voltage options, shown in bold , are available.Contact the factory for other output voltages between 1.5V and 4.5V.
