The ADM1191 is an integrated current sense amplifier that offers digital current and voltage monitoring via an on-chip, 12-bit analog-to-digital converter (ADC), communicated through an I2C interface. An internal current sense amplifier senses voltage across the sense resistor in the power path via the VCC pin and the SENSE pin.A 12-bit ADC can measure the current seen in the sense resistor, as well as the supply voltage on the VCC pin.An industry-standard I2C interface allows a controller to read current and voltage data from the ADC. Measurements can be initiated by an I2C command or via the convert (CONV) pin. The CONV pin is especially useful for synchronizing reads on multiple ADM1191 devices. Alternatively, the ADC can run continuously, and the user can read the latest conversion data whenever it is required. Up to 16 unique I2C addresses can be created, depending on the way the A0 pin and the A1 pin are connected.A SETV pin is also included. A voltage applied to this pin is internally compared to the output voltage on the current sense amplifier. The output of the SETV comparator asserts when the current sense amplifier output exceeds the SETV voltage. When this event occurs, the ALERTB output asserts.The ALERTB output can be used as a flag to warn a micro-controller or field programmable gate array (FPGA) of an overcurrent condition. ALERTB outputs of multiple ADM1191 devices can be tied together and used as a combined alert.The ADM1191 is packaged in a 10-lead MSOP.APPLICATIONS Power monitoring/power budgeting Central office equipment Telecommunication and data communication equipment PCs/servers

The ADM1272 ?is a hot swap controller that allows a circuit board to be removed from or inserted into a live backplane. It also features current, voltage, and power readback via an integrated 12-bit analog-to-digital converter (ADC), accessed using a PMBus? interface. This device is able to withstand up to 120 V, which makes it very robust in surviving surges and transients commonly associated with high voltage systems, usually clamped using protection devices such as transient voltage suppressors (TVSs) that can often exceed 100 V.The load current, ILOAD, is measured using an internal current sense amplifier that measures the voltage across a sense resistor in the power path via the SENSE+ and SENSE? pins. A default current limit sense voltage of 30 mV is set, but this limit can be?adjusted down, if required, using a resistor divider network from the VCAP regulator output voltage to the ISET pin. An additional resistor can also be placed from ISET to VIN (or VOUT) to allow the current limit to track inversely with the rail voltage. This resistor allows an approximate system power limit to be used.The ADM1272 ?limits the current through the sense resistor by controlling the gate voltage of an external N channel field effect transistor (FET) in the power path. The sense voltage, and therefore the load current, is maintained below the preset maximum. The ADM1272 ?protects the external FET by monitoring and limiting the energy transfer through the FET while the current is being controlled. This energy limit is set by the choice of components connected to the EFAULT pin (for fault protection mode) and the ESTART pin during startup. Therefore, different energy limits can be set for start-up and normal fault conditions. During startup, inrush currents are maintained very low and different areas of the safe operating area (SOA) curve are of interest, whereas during fault conditions, the currents can be much higher.The controller uses the drain to source voltage (VDS) across the FET to set the current profile of the EFAULT and ESTART pins and, therefore, the amount of much energy allowed to be transferred in the FET. This energy limit ensures the MOSFET remains within the SOA limits. Optionally, use a capacitor on the DVDT pin to set the output voltage ramp rate, if required. In case of a short-circuit event, a fast internal overcurrent detector responds in hundreds of ns and signals the gate to shut down. A 1.5 A pull-down device ensures a fast FET response. The gate then recovers control within 50 ?s to ensure minimal disruption during conditions, such as line steps and surges. The?ADM1272 ?features overvoltage (OV) and undervoltage (UV) protection, programmed using external resistor dividers on the UVH, UVL, and OV pins. The use of two pins for undervoltage allows independent accurate rising and falling thresholds. The PWRGD output pin signals when the output voltage is valid and the gate is sufficiently enhanced. The validity of VOUT is determined using the PWGIN pin.The 12-bit ADC measures the voltage across the sense resistor, the supply voltage on the SENSE+ pin, the output voltage, and the temperature using an external NPN/PNP device. A PMBus interface allows a controller to read data from the ADC. As many as 16 unique I2C addresses can be selected, depending on how the two ADRx pins are connected. The?ADM1272 is available in a custom 48-lead LFCSP (7 mm ? 8 mm) with a pinstrap mode that allows the device to be configured for automatic retry or latchoff when an overcurrent (OC) fault occurs.Applications 48 V/54 V systems Servers Power monitoring and control/power budgeting Central office equipment Telecommunication and data communication equipment Industrial applications

The RS-485 transceivers are available in a number of spacesaving packages, including the 10-lead, 3 mm ? 3 mm lead framechip-scale package (LFCSP), the 8-lead or 10-lead, 3 mm ? 3 mmmini small outline package (MSOP), and the 8-lead or 14-lead,narrow body standard small outline packages (SOIC_N).Models with operating temperature ranges of ?40?C to +125?Cand ?40?C to +85?C are available. Excessive power dissipation caused by bus contention or byoutput shorting is prevented by a thermal shutdown circuit. If asignificant temperature increase is detected in the internal drivercircuitry during fault conditions, this feature forces the driveroutput into a high impedance state. The ADM3061E/ADM3062E/ADM3063E/ADM3064E/ADM3065E/ADM3066E/ADM3067E/ADM3068E guarantee alogic high receiver output when the receiver inputs are shorted,open, or connected to a terminated transmission line with alldrivers disabled. Table 2 in the data sheet presents an overview of the ADM3061E/ADM3062E/ADM3063E/ADM3064E/ADM3065E/ADM3066E/ADM3067E/ADM3068E data rate capability across temperature, power supply,and package options.

The ADM3095E is a 3.0 V to 5.5 V, 2.5 Mbps, RS-485 transceiverthat features up to ?42 V ac/dc peak bus overvoltage faultprotection on the RS-485 bus pins. This device is designed towithstand overvoltage faults, such as short circuits directly to powersupplies, and overvoltage faults, such as ?24 V ac suppliesconnected in error to the RS-485 A and B bus pins. TheADM3095E is an RS-485 transceiver that integrates IEC 61000-4-5Level 4 surge protection, allowing up to ?4 kV protection onthe RS-485 bus pins. The device has IEC 61000-4-4 Level 4electrical fast transient (EFT) protection up to ?2 kV, andIEC 61000-4-2 Level 4 electrostatic discharge (ESD) protectionon the bus pins, allowing the device to withstand up to ?15 kVon the transceiver interface pins without latch-up or damage.This device has an extended common-mode input voltage rangeof ?25 V to improve data communication reliability in noisyenvironments over long cable lengths where ground loop voltagesare possible. The combination of extended common-mode inputvoltage range, overvoltage fault protection, surge protection, EFTprotection, and ESD protection make the ADM3095E acompletely integrated electromagnetic compatibility (EMC)protected RS-485 transceiver.The ADM3095E also features a logic supply pin, VIO, for a flexibledigital interface, operational to voltages as low as 1.62 V. TheADM3095E is PROFIBUS? compliant with a high driverdifferential output voltage, VOD, of 2.1 V minimum at power supplyvoltages greater than 4.5 V. The device is fully characterized overextended operating temperature ranges, with options of ?40?C to+125?C, and is available in a 16-lead, narrow body SOIC package..Applications Heating ventilation and air conditioning (HVAC) networks Industrial field buses Building automation Utility networks
