TMP422-EP (ACTIVE) Dual remote and local temperature sensor with N-factor and series-R correction

Dual remote and local temperature sensor with N-factor and series-R correction - TMP422-EP
Datasheet
 

Description

The TMP422 is a remote temperature sensor monitor 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 configure the device.

The TMP422 includes series resistance cancellation, programmable non-ideality factor, wide remote temperature measurement range (up to 150°C), and diode fault detection.

The TMP422 is available in a SOT23-8 package.
