AP1346

AP1346/1347 Two Coil Fan Motor Predriver Features - Compatible to a Hall element - Operating voltage (VCC) : 4V to 28V - Lock shutdown and automatic restart - Rotation detection (RD) output name as AP1347 - Speed indication output (FG) named as AP1346 - Output current IO=70mA (max) - Operating temperature (Topr) : -30ºC to +85ºC - SOP8 package - Include Thermal Shutdown circuit General Description 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, the IC 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.
