FEATURES
SOT23-8 PACKAGE ±1°C REMOTE DIODE SENSOR (MAX) ±1.5°C LOCAL TEMPERATURE SENSOR (MAX) SERIES RESISTANCE CANCELLATION n-FACTOR CORRECTION TWO-WIRE/SMBus SERIAL INTERFACE MULTIPLE INTERFACE ADDRESSES DIODE FAULT DETECTION RoHS COMPLIANT AND NO Sb/Br
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°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 TMP421 and TMP422 include series resistance cancellation, programmable non-ideality factor, wide remote temperature measurement range (up to +150°C), and diode fault detection. The TMP421 and TMP422 are both available in an 8-lead, SOT23 package.
