- Compatible to a Hall element - Operating voltage (VCC) 28V - Lock shutdown and automatic restart - Rotation detection (RD) output - Output current IO=70mA (max) - Operating temperature (Topr) - SOP8 package - Include Thermal Shutdown circuit

The AP1307 fan motor predriver is suited for two-coil brush-less DC fan. All functions, including lock shutdown, automatic restart, rotation detection (RD), have been incorporated into one chip. When the motor is under lock condition, lock shutdown function turns off the output current. When the lock condition is removed, the IC automatically restarts and allows DC fan to run. In addition, the RD function is to detect the motor status.
