3-Phase Brushless DC Motor Pre-Driver

The A4938 is a complete 3-phase brushless DC (BLDC) motor pre-driver, supplying direct, high-current gate drive of an all N-channel power MOSFET 3-phase bridge. The device has three Hall-element inputs, a sequencer for commutation control, fixed off-time pulse width modulation (PWM) current control, \n• Synchronous rectification for low power dissipation \n• Hall element inputs \n• Dead time protection \n• Standby mode \n• Overvoltage protection ;
