The TC651 is an integrated temperature sensor and brushless DC fan controller with automatic fan shutdown for power savings. It measures junction temperature and controls fan speed proportionally from 40% to 100% using PWM output, with ±1°C accuracy between 25°C and 70°C. The device operates from 2.8V to 5.5V and consumes 50µA typical supply current. It includes a dedicated overtemperature alert (T_OVER) output with a programmable trip point and 5°C hysteresis. The TC651CGVUA variant selects a low temperature threshold of 35°C and high threshold of 55°C. It is packaged in an 8-pin MSOP, measuring 3.00mm width, and supports an operating temperature range from -40°C to +125°C.
