A4938 pre-driver equivalent, 3-phase brushless dc motor pre-driver.
▪ Drives 6 N-channel MOSFETs ▪ Synchronous rectification for low power dissipation ▪ Internal UVLO and thermal shutdown circuitry ▪ Hall element inputs ▪ PWM current limi.
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-.
