onsemi Thermal Management ADT7463ARQ-REEL7

The ADT7463ARQ-REEL7 is a comprehensive thermal management and voltage monitoring solution designed for noise-sensitive applications requiring active cooling. It can monitor multiple supply voltages, including 12V, 5V, and 2.5V, as well as its own supply voltage. The device supports temperature monitoring for up to two remote sensor diodes and its internal temperature, making it suitable for precise thermal management. This controller can manage the speed of up to four fans, optimizing their operation to minimize acoustic noise through an automatic fan speed control loop. It features a dynamic TMIN control mode that intelligently manages system thermals and acoustics. Additionally, the ADT7463 provides critical thermal protection via a bidirectional THERM pin, which helps prevent overheating of the system or components. The device is compliant with SMBus 2.0 specifications and is Pb-free, making it a suitable choice for environmentally conscious designs. Applications include low acoustic noise PCs and networking or telecommunications equipment, where efficient thermal management is essential.
