ADT7468ARQZ

GENERAL
The ADT7468 dBCool controller is a thermal monitor and multiple PWM fan controller for noise sensitive or power sensitive applications requiring active system cooling.
The ADT7468 can drive a fan using either a low or high frequency drive signal, monitor the temperature of up to two remote sensor diodes plus its own internal temperature, and measure and control the speed of up to four fans, so that they operate at the lowest possible speed for minimum acoustic noise.
FEATURES Monitors up to 5 voltages Controls and monitors up to 4 fans High and low frequency fan drive signal 1 on-chip and 2 remote temperature sensors Series resistance cancellation on the remote channel Extended temperature measurement range, up to 191°C Dynamic TMIN control mode intelligently optimizes system acoustics Automatic fan speed control mode manages 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 THERM input 2-wire, 3-wire, and 4-wire fan speed measurement Limit comparison of all monitored values Meets SMBus 2.0 electrical specifications (fully SMBus 1.1-compliant)
