... Single-phase full-wave motor driver BA6427F The BA6427F is a single-phase full-wave motor driver for fan motors. By using this driver, a single-phase, full-wave motor driver circuit can be built with fewer components than a circuit using operational amplifiers. Lock detection and automatic restart mechanisms, which are required for fan motors, are also built in. A rotational-speed sensing output pin is provided for Ho output ...

... When the lock condition is cleared, the IC automatically restarts and allow the motor to run. In the BA6427F, automatic restart is performed as fol- lows. A motor lock condition is detected when the Hall signal stops switching. The output is OFF when the LD pin is be- ing charged ...
