ADT7473: Remote Thermal Monitor and Fan Controller
The ADT7473/ADT7473-1 controller is a thermal monitor and multiple PWM fan controller for noise sensitive or power sensitive applications requiring active system cooling. The ADT7473/ADT7473-1 can drive a fan using either a low or high frequency drive signal, monitor the temperature of up to two remote sensor diodes plus its own internal temperature, and measure and control the speed of up to four fans so they operate at the lowest possible speed for minimum acoustic noise.
特性- Controls and monitors up to 4 fans
- High and low frequency fan drive signal
- 1 on-chip and 2 remote temperature sensors
- Series resistance cancellation on the remote channel
- Extended temp measurement range, up to 191°C
- Dynamic TMIN control mode optimizes system acoustics intelligently
- 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
