The TC642B/TC647B motor driver is a PWM fan speed controller designed for efficient operation in various applications, including personal computers, servers, and general-purpose fan speed control. It operates within a supply voltage range of 3.0V to 5.5V and supports a maximum output current of 5mA. The device features temperature-proportional fan speed control using pulse width modulation, which helps reduce acoustic noise and extend fan life. Key functionalities include a fan auto-restart feature, fault detection through Microchip's FanSense,Ñ¢ technology, and a shutdown mode for energy efficiency. The TC642B variant additionally provides over-temperature indication. The motor driver is housed in a compact 8-pin SOIC package, making it suitable for space-constrained designs. The operating temperature range is specified from -40¬8C to +85¬8C, ensuring reliability in diverse environments.
