Description
The A4933 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 A4933
to operate with a reduced gate drive, down to 5.5 V.
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 DC (100% duty
cycle) operation.
Full control over all six power FETs in the 3-phase bridge is
provided, allowing motors to be driven with block commutation
or sinusoidal excitation. The power FETs are protected from
shoot-through by integrated crossover control and resistor-
adjustable dead time.
Bridge current can be measured using an integrated current
sense amplifier. This is an uncommitted differential amplifier
with a below-ground common mode range allowing it to be
used in low-side current sense applications. Gain and offset
are defined by external resistors.
