Description

The TMP421 and TMP422 are remote 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 FPGAs.

Remote accuracy is ±1 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 TMP421.

the TMP421 and TMP422 include series resistance cancellation, programmable non-ideality factor, wide remote temperature measurement range (up to +150), and diode fault detection.They are both available in an 8-lead, SOT23 package
