TMP422AIDCNT Datasheet PDF - TI

●The TMP422AIDCNT 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
