The TMP431 and TMP432 are remote temperature sensor monitors with a built-in localtemperature sensor. The remote temperature sensor diode-connected transistors are typicallylow-cost, NPN- or PNP-type transistors or diodes that are an integral part of microcontrollers,microprocessors, or FPGAs.

Remote accuracy is ±1°C for multiple device manufacturers, with no calibration needed.The Two-Wire serial interface accepts SMBus write byte, read byte, send byte, and receive bytecommands to program the alarm thresholds and to read temperature data.

The TMP43x include beta compensation (correction), series resistance cancellation,programmable non-ideality factor, programmable resolution, programmable threshold limits, minimumand maximum temperature monitors, wide remote temperature measurement range (up to 150°C), anddiode fault detection and temperature alert function.

The TMP431 is available in aVSSOP-8 package and the TMP432 is available in aVSSOP-10 package.
