The TMP431 and TMP432 are remote temperature sensor monitors with a built-in local temperature sensor. The remote temperature sensor diode-connected transistors are typically low-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 byte commands 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, minimum and maximum temperature monitors, wide remote temperature measurement range (up to 150°C), and diode fault detection and temperature alert function.

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