The ON Semiconductor ADT7473ARQZ-REEL is an integrated circuit designed for thermal monitoring and multi-fan control in noise-sensitive or power-sensitive applications. This device can manage up to four fans, operating them at the lowest possible speed to minimize acoustic noise. It features an on-chip temperature sensor and can monitor up to two remote sensor diodes.
The ADT7473ARQZ-REEL supports both high and low frequency fan drive signals and offers series resistance cancellation on remote channels. Its automatic fan speed control loop optimizes cooling based on measured temperature, while a dynamic TMIN control mode intelligently manages system thermals and acoustics. The device also provides critical thermal protection via a bidirectional THERM pin.
This IC operates within a voltage range of 3V to 3.6V and has an operating temperature range of -40°C to 125°C. It is available in a 16-QSOP package and is suitable for surface mount applications. The output type is SMBus, and it supports 3-wire and 4-wire fan speed measurement. The device meets SMBus 2.0 electrical specifications and is Pb-Free and Halogen Free compliant.
