ADT7463: Remote Thermal Controller and Voltage Monitor
The ADT7463 controller is a complete systems monitor and multiple PWM fan controller for noise-sensitive applications requiring active system cooling. It can monitor 12 V, 5 V, and 2.5 V CPU supply voltages, plus its own supply voltage. It can monitor the temperature of up to two remote sensor diodes, plus its own internal temperature. It can measure and control the speed of up to four fans so that they operate at the lowest possible speed for minimum acoustic noise. The automatic fan speed control loop optimizes fan speed for a given temperature.
Features- Monitors up to 5 supply voltages
- Controls and monitors up to 4 fan speeds
- One on-chip and 2 remote temperature sensors
- Monitors up to 6 processor VID bits
- Dynamic TMIN Control Mode optimizes systems 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
- 2-wire and 3-wire fan speed measurement
- Limit comparison of all monitored values
