A4935 Automotive 3-Phase MOSFET Driver

The A4935 is a 3-phase controller for use with N-channel external power MOSFETs and is specifically designed for automotive applications. A unique charge pump regulator provides full (>10 V) gate drive for battery voltages down to 7 V and allows the A4935 to operate with a reduced gate drive, down t.
