The ADT7476AARQZ-R from 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 internal and up to two remote temperature sensors, providing comprehensive thermal management.
It features automatic fan speed control, optimizing fan speed based on measured temperature to minimize acoustic noise. The device supports high and low frequency fan drive signals and can measure fan speed using 3-wire or 4-wire configurations. It monitors up to five voltages and controls up to four fans, offering enhanced performance and protection.
The ADT7476AARQZ-R operates within a voltage range of 3V to 3.6V and has an operating temperature range of -40°C to 125°C. It is supplied in a 24-QSOP package and is suitable for surface mount applications. The device meets SMBus 2.0 electrical specifications and is RoHS3 compliant, Pb-free, and halogen-free.
Key features include an extended temperature measurement range up to 191°C, enhanced acoustic mode for reduced fan speed perception, and thermal protection via a THERM output. It also monitors performance impact and includes a thermal control circuit via a THERM input.
