ADT7473ARQZ-1R7 Description

Short technical summary and product information.

The ADT7473ARQZ-1R7 from ON Semiconductor is a versatile thermal monitor and fan controller designed for noise and power-sensitive applications requiring active system cooling. This device can manage up to four fans, driving them with either high or low-frequency signals to optimize acoustic performance.

 

It integrates one on-chip temperature sensor and can monitor up to two remote sensor diodes, providing comprehensive thermal oversight. The ADT7473ARQZ-1R7 operates within a voltage range of 3V to 3.6V and has an operating temperature range of -40°C to 125°C. Its accuracy for temperature sensing is ±2.5%.

 

The controller features automatic fan speed control, a dynamic TMIN control mode for intelligent thermal and acoustic management, and an enhanced acoustic mode to reduce the perception of changing fan speeds. It also includes a thermal protection feature via a bidirectional THERM pin, preventing system or component overheating. The device supports 3-wire and 4-wire fan speed measurement and meets SMBus 2.0 electrical specifications.

 

Packaged in a 16-QSOP, the ADT7473ARQZ-1R7 is suitable for surface mount applications. It is Pb-Free and Halogen Free, complying with RoHS standards.
