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.
