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. Built-in protection circuitry

prevents damage to the MOSFET bridge as well as the drive IC and

includes overvoltage shutdown, overtemperature shutdown,

overcurrent shutdown, and undervoltage shutdown.

The device is parametrically specified over ambient temperature

range of -40

°C ≤ T
