ADT7460: Thermal Management Controller
The ADT7460 controller is a thermal monitor and multiple PWM fan controller for noise-sensitive applications requiring active system cooling. 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. A unique dynamic Tmin control mode enables the system thermals/acoustics to be intelligently managed. The effectiveness of the system's thermal solution can be monitored using the THERM input. The ADT7460 also provides critical thermal protection to the system by using the bidirectional THERM pin as an output to prevent system or component overheating.
特性- Controls and monitors up to 4 fan speeds
- 1 on-chip and 2 remote temperature sensors
- 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 via the THERM output
- Processor thermal control circuit via THERM input
- 2-wire and 3-wire fan speed measurement
- Limit comparison of all monitored values
