ADT7490 Datasheet Dbcool Remote Thermal Monitor And Fan Controller

Manufacturer: Analog Devices

Overview: .. dBCool Remote Thermal Monitor and Fan Controller with PECI Interface.

General Description

The ADT7490 is a dBCool® thermal monitor and multiple PWM fan controller for noise-sensitive or power-sensitive applications requiring active system cooling.

The ADT7490 includes a local temperature sensor, two remote temperature sensors including series resistance cancellation, and monitors CPU temperature with a PECI interface.

The ADT7490 can drive a fan using either a low or high frequency drive signal, and measure and control the speed of up to four fans so they operate at the lowest possible speed for minimum acoustic noise.

Key Features

  • Temperature measurement: 1 local on-chip temperature sensor 2 remote temperature sensors 3-current external temperature sensors with series resistance cancellation (SRC) PECI interface for CPU thermal information and support of up to 4 PECI inputs on one pin Fan drive and fan speed control 3 high frequency or low frequency PWM outputs for use with 3-wire or 4-wire fans 4 TACH inputs to measure fan speed OS independent automatic fan speed control based on thermal information Dynamic TMIN control.
