    产品信息

    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.
    • 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 T
    • control mode to optimize system acoustics
    • Default startup at 100% PWM for all fans for robust operation
