  • The ADT7476A controller is a thermal monitor and multiple PWM fan controller for noise-sensitive or power-sensitive applications requiring active system cooling. The ADT7476A can drive a fan using either a low or high frequency drive signal and can monitor the temperature of up to two remote sensor diodes plus its own internal temperature. The part also measures and controls the speed of up to four fans, so the fans operate at the lowest possible speed for minimum acoustic noise.
  • Features
  • Monitors up to 5 Voltages
  • Improved TACH and PWM Performance
  • Controls and Monitors up to Four Fans
  • High and Low Frequency Fan Drive Signal
  • One on-chip and Two Remote Temperature Sensors
  • Extended temp measurement range, up to 191°C
  • Automatic fan speed control mode controls system cooling based on measured temperature
  • Enhanced acoustic mode dramatically reduces user perception of changing fan speeds
  • Thermal Protection Feature via THERM Output
  • Thermal control circuit via THERM input
  • 3-wire and 4-wire fan speed measurement
