ADT7475ARQZ-RL7 thermal management IC
The ADT7475ARQZ-RL7 is a high-performance, remote thermal sensor and fan controller from onsemi, housed in a compact 16-QSOP package, designed for precise temperature monitoring and active cooling management in electronic systems. This device integrates a local temperature sensor and supports up to two remote thermal diode sensors (such as those in CPUs/GPUs) to measure temperatures from -64°C to +191°C with high accuracy, operating from a single 3.0V to 3.6V supply and across the full industrial temperature range of -40°C to +125°C.
Its key features include a programmable digital PWM fan speed controller with multiple control modes (automatic, manual, software-based) to optimize cooling efficiency and minimize acoustic noise. The device offers a high-resolution 10-bit analog-to-digital converter (ADC) for temperature measurement and supports a two-wire SMBus/I²C-compatible serial interface for communication with the host system. Additional highlights are its programmable temperature limits with interrupt outputs for over-temperature warnings, the ability to monitor its own supply voltage, and an integrated fan tachometer input for closed-loop fan speed monitoring, ensuring reliable thermal management.
