A3930KJP-T, Контроллер бесщеточного DC, МОП-транзисторный привод, 5.5В - 50В питание, 50В/1мА/12 выходов

The A3930KJP-T is a 3-phase hall short detection brushless DC (BLDC) Motor Controller for use with N-channel external power MOSFETs. It incorporates much of the circuitry required to design a cost effective 3-phase motor drive system and has been specifically designed for automotive applications. A key automotive requirement is functionality over a wide input supply range. Unique charge pump regulator provides adequate gate drive for battery voltages down to 7V and allows the device to operate with a reduced gate drive at battery voltages down to 5.5V. 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 14V. A bootstrap capacitor is used to provide the above-battery supply voltage required for N-channel MOSFETs. An internal charge pump for the high-side drive allows for DC operation.
