dBCool Remote Thermal Monitor and Fan

Controller with PECI Interface

ADT7490

FEATURES

GENERAL DESCRIPTION

Temperature measurement:

1 local on-chip temperature sensor

2 remote temperature sensors

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

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 T_MINcontrol mode to optimize system acoustics

Default startup at 100% PWM for all fans for robust

operation

Bidirectional THERM/SMBALERT pin to flag out-of-limit and

overtemperature conditions

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.

The automatic fan speed control loop optimizes fan speed

for a given temperature using the PECI, remote, or local

temperature information. The effectiveness of the system’s

THERM

thermal solution can be monitored using the

The ADT7490 also provides critical thermal protection to

the system using the bidirectional

an output to prevent system or component overheating.

GPIO functionality to support extra features

Can be used for loadline setting for voltage regulation,

LED control, or other functions

_MONmonitoring for CPU current and power information

Footprint and register compatible with ADT7473/ADT7475/

ADT7476/ADT7476A family of fan controllers

SMBus interface with addressing capability for up to

3 devices
