ADT7490: Remote Thermal Monitor and Fan Controller with PECI Interface

Description: The ADT7490 is a thermal monitor and multiple PWM ...
  • The ADT7490 is a 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.
  • Features
  • 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
  • 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 mode to optimize system acoustics
  • Default startup at 100% PWM for all fans for robust operation
