ADT7483A - Dual Channel Temperature Sensor and Over Temperature Alarm

Description

The ADT7483A1 is a three-channel digital thermometer and under/over temperature alarm, intended for use in PCs and thermal management systems.

It can measure the temperature in two remote locations, for example, the remote thermal diode in a CPU or GPU, or a discrete diode connected transistor.

Features

  • 1 local and 2 remote temperature sensors 0.25°C resolution/1°C accuracy on remote channels 1°C resolution/1°C accuracy on local channel Extended, switchable temperature measurement range 0°C to 127°C (default) or.
  • 64°C to +191°C 2-wire SMBus serial interface with SMBus alert support Programmable over/under temperature limits Offset registers for system calibration Up to 2 overtemperature fail-safe THERM outputs Small 16-lead QSOP package 240 μA operating current, 5 μA standby current GE.
