3 Description
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.
