The 33395 simplifies the design of high-power BLDC motor control design by combining the gate drive, charge pump, current sense, and protection circuitry necessary to drive a three-phase bridge configuration of six N-channel power MOSFETs. Mode logic is incorporated to route a pulse width modulation (PWM) signal to either the low-side MOSFETs or high-side MOSFETs of the bridge, or to provide complementary PWM outputs to both the low- and high-sides of the bridge.
