The A4939 is a three-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 at battery voltages down to 7 V and allows the A4939 to operate with reduced gate drive at battery voltages down to 5.5 V.
A bootstrap capacitor is used to provide the above battery supply voltage required for N-channel MOSFETs.
