ADT7466 dBCool Remote Thermal Controller and Voltage Monitor

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.

Features

Monitors two analog voltages or thermistor temperature inputs One on-chip and up to two remote temperature sensors with series 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 user perception 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 seri.
