Quick Detail:
dBCool Remote Thermal Controller and Voltage Monitor
Description:
The ADT7466 dBCool controller is a complete thermal monitor and dual fan controller for noise-sensitive applications requiring active system cooling. It can monitor two analog voltages or the temperature of two thermistors, 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 two fans so that theyoperate at the lowest possible speed for minimum acoustic noise. The automatic fan speed control loop optimizes fan speed for a given temperature. The effectiveness of the system’sthermal solution can be monitored using the PROCHOT input to time and monitor the PROCHOT output of the processor.
Applications:
Monitors two analog voltages or thermistor temperature inputs
One on-chip and up to two remote temperature sensors withseries resistance cancellation
Controls and monitors the speed of up to two fans
Automatic fan speed control mode controls system cooling based on measured temperature
Enhanced acoustic mode dramatically reduces userperception of changing fan speeds
Thermal protection feature via THERM output monitors performance impact of Intel® Pentium® 4 processor thermal control circuit via PROCHOT input
3-wire fan speed measurement
Limit comparison of all monitored values
SMBus 1.1 serial interface
