The AP1346/7 fan motor predriver is suited for two-coil brush-less DC fan. All functions, including lock shutdown, automatic restart, speed indication (FG), have been integrated into one chip. When the motor is under lock condition, lock shutdown function turns off the output. When the lock condition is removed, AP1347 automatically restarts and allows DC fan to run. In addition, the FG function is to indicate the rotation speed and the RD function is to detect the motor status.
