FD178A drivers equivalent, single coil brushless dc motor drivers.
z Support single-phase full wave Brushless DC Motor Driver z Built-in Hall sensor input signal amplifier z PWM control circuit z Low voltage startup (VDD=2V) z High drivi.
The output driver node O1/O2 are in drive/sink state when V(HP) > V(HN) and vice versa
The lock and auto-restart do.
