MAX6581 - 8-Channel Temperature Sensor

General Description

The MAX6581 precision multichannel temperature sensor monitors its own temperature and the temperatures of up to seven external diode-connected transistors.

All temperature channels have programmable alert and overtemperature thresholds.

Key Features

  • Eight Channels to Measure Seven Remote and One Local Temperature.
  • 11-Bit, 0.125°C Resolution.
  • High Accuracy of ±1°C (max) from +60°C to +100°C (Remote Channels).
  • -64°C to +150°C Remote Temperature Range.
  • Programmable Undertemperature/Overtemperature Alerts.
  • SMBus/I2C-Compatible Interface.
  • Two Open-Drain Alarm Outputs (ALERT and OVERT).
  • Resistance Cancellation on All Remote Channels.

MAX6581 General Description The MAX6581 precision multichannel temperature sensor monitors its own temperature and the temperatures of up to seven external diode-connected transistors. All temperature channels have programmable alert and overtemperature thresholds. When the measured temperature of a channel crosses the respective threshold, a status bit is set in one of the status registers. Two open-drain alarm outputs (ALERT and OVERT) assert corresponding to these bits in the status register(s).
