Automotive 3-Phase BLDC Controller And MOSFET Driver

The A3930 and A3931 are 3-phase brushless dc (BLDC) Motor Controllers for use with N-channel external Power MOSFETs They incorporate much of the circuitry required to design a cost effective three-phase motor drive system, and have been specifically designed for automotive applications.
A key automotive requirement is functionality over a wide input supply range. A unique Charge Pump Regulator provides adequate (>10 V) Gate drive for battery voltages down to 7 V, and allows the device to operate with a reduced Gate drive at battery voltages down to 5.5 V. Power dissipation in the Charge Pump is minimized by switching from a voltage doubling mode at low supply voltage to a dropout mode at the nominal running voltage of 14 V.
