MAX6638 - Temperature Monitor

General Description

The MAX6638 thermal-management sensor includes internal (local) and external (remote) digital temperature sensors and two independent SMBus™ serial ports.

The remote temperature accuracy is ±1.0°C, and the local temperature accuracy is ±2°C.

Key Features

  • extended temperature resolution data available in 0.125°C increments. The MAX6638 provides three system alarms: channel 1 alert (ALERT1), overtemperature (OVERT1), and channel 2 alert (ALERT2) that contain programmable thresholds set independently by each of the SMBus serial ports (SMBus1 and SMBus2). Each alert output asserts when any of four temperature conditions is violated: local overtemperature, remote overtemperature, local undertemperature, or remote undertemperature. The overtemperature.
