illustrate

The remote temperature sensor monitoring of the TMP431 and TMP432 is a built-in local temperature sensor. The transistor to which a remote temperature sensor diode is connected is typically a low-cost, NPN- or PNP-type transistor or diode, which is a component of a microcontroller, microprocessor, or FPGA.

Remote accuracy is ± 1°C between multiple IC manufacturers and no calibration required. The two-wire serial interface accepts SMBus write bytes, read bytes, send bytes, and receive byte commands to program alarm thresholds and read temperature data.

The tested TMP431/32 includes compensation (correction), series resistance cancellation, programmable non-ideal factors, programmable resolution, programmable threshold limits, minimum and maximum temperature displays, wide remote temperature measurement range (up to +150 °C) and diode fault detection and temperature alarm functions.
