The A3935 is a three-phase power MOSFET controller designed specifically for automotive applications requiring high-power motors. It integrates a pulse-frequency modulated boost converter to create a constant supply voltage for driving external n-channel power MOSFETs from low-voltage battery supplies. The device includes bootstrap circuits for high-side gate drivers and an internal LDO regulator for the gate-driver supply.
