Dual Remote and Local Temp Sensor with Automatic Beta, N-Factor and Series-R Correction - TMP432

TMP432 (ACTIVE)

Dual Remote and Local Temp Sensor with Automatic Beta, N-Factor and Series-R Correction

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 IC 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 TMP431/32 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.
