Features

* 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 driving capability z Lock detection and automatic self-restart z Power polarity reverse protection z Thermal shut down protection circu

Applications

* 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 not require an external capacitor for a timing counting purpose. The driver will be shutdown approximately 1 second after the motor is lock and the auto-restart is activated every
