Product Overview

The TMP421AIDCNT is a Remote Temperature Sensor Monitor with a built-in local temperature sensor. The remote temperature sensor diode-connected transistors are typically, 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 device include wide remote temperature measurement range (up to +150°C) and diode fault detection.
  • Programmable non-ideality factor
  • Series resistance cancellation
  • η-Factor Correction
  • 2-wire/SMBus serial interface
  • Multiple interface addresses
