The ADT7476AARQZ by ON Semiconductor is a versatile thermal controller and voltage monitor designed for noise-sensitive and power-sensitive applications requiring active system cooling. This integrated circuit can monitor the temperature of its own internal sensor plus up to two remote sensor diodes, providing comprehensive thermal management.
The device offers control and monitoring for up to four fans, operating them at the lowest possible speed to minimize acoustic noise. It features automatic fan speed control, optimizing fan speed based on measured temperature, and an enhanced acoustic mode to reduce the perception of changing fan speeds. The ADT7476AARQZ also provides critical thermal protection via a bidirectional THERM pin.
Key electrical features include a 3.3V operating voltage and SMBus 2.0 interface compatibility. The device supports both high and low frequency fan drive signals and can measure fan speed using 3-wire or 4-wire methods. It monitors up to five voltages and compares all monitored values against set limits. The ADT7476AARQZ is supplied in a 24-QSOP surface mount package and operates within a temperature range of -40°C to 125°C.
