3 Description

The TMP401 is a remote temperature sensor monitor

with a built-in local temperature sensor. The remote sensor is capable of monitoring the temperature of

any external PN junction. Typical sense elements

include low-cost NPN- or PNP-type transistors and

diodes, or accessible thermal diodes integrated within microcontrollers, microprocessors, or field-

programmable gate arrays (FPGAs).

The accuracy of the remote sensor 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 alarm thresholds and to read

temperature data.

Features included in the TMP401 are series

resistance cancellation, wide remote temperature measurement range (up to +150°C), diode fault

detection, and temperature alert functions.
