Three-Phase Gate Driver IC
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) or a complementary PWM output signal to either low-side or high-side
MOSFETs of the bridge.
Detection and drive circuitry are also incorporated to control a reverse battery protection high-side
MOSFET switch.
PWM frequencies up to 28 kHz are possible.
