3 Description

The TMP421-Q1, TMP422-Q1, and TMP423-Q1

devices are single, dual, and triple remote,

automotive-qualified 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 field-programmable gate arrays

(FPGAs).

Remote accuracy is ±1°C for multiple device

manufacturers, with no calibration needed. The twowire

serial interface accepts SMBus write byte, read

byte, send byte, and receive byte commands to

configure the device.

The TMP421-Q1, TMP422-Q1, and TMP423-Q1

include series resistance cancellation, programmable

non-ideality factor, wide remote temperature

measurement range (up to +150°C), and diode fault

detection.

The TMP421-Q1, TMP422-Q1, and TMP423-Q1 are

all available in an 8-pin SOT-23 package.
