ADT7490 Temperature Monitor with Fan Control (PECI Interface)

The ADT7490 temperature monitor with fan control is ideal for designs that require economical and minimal noise system cooling. It is designed to;

a) measure and monitor ambient temperature
b) measure and monitor up to 2 remote temperature sensors
c) monitor and control the fan speed of up to 4 fans

The ADT7490 also has the added functionality of series resistance cancellation and the ability to monitor a CPU temperature with it's PECI (platform environmental control interface).


-3 PWM outputs (High frequency or low frequency)
-4 tachometer inputs
-SMBus serial interface
- 2 GPIO pins
-TMIN control mode
-IMON monitoring
