ADT7466ARQZ - Analog Devices - dBCool Remote Thermal Controller and Voltage Monitor



Detailed Product Description

Quick Detail:


 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 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.





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
