ADT7470 - Temperature Sensor Hub and Fan Controller

Datasheet Summary

Description

The ADT74701 controller is a multichannel temperature sensor and PWM fan controller and fan speed monitor for systems requiring active cooling.

It is designed to interface directly to an I2C® bus.

Features

  • Monitors up to 10 remote temperature sensors Monitors and controls speed of up to 4 fans independently PWM outputs drive each fan under software control FULL_SPEED input allows fans to be blasted to maximum speed by external hardware.
