3 Description

The DRV3233 is an integrated smart gate driver

for 12-V and 24-V automotive three-phase BLDC

applications. The device provides three half-bridge

gate drivers, each capable of driving high-side and

low-side N-channel power MOSFETs. The DRV3233

generates the correct gate drive voltages using an

integrated bootstrap diode and a GVDD charge

pump. The Smart Gate Drive architecture supports

configurable peak gate drive current from 0.8-mA

up to 1-A source and 2-A sink. The DRV3233 can

operate from a single power supply with a wide input

range of 4.5 to 60-V. A trickle charge pump enables

100% PWM duty cycle control, and provides overdrive

supply voltage for external switches.

The DRV3233 provides low-side current sense

amplifiers to support resistor based low-side current

sensing. The low offset of the amplifiers enables the

system to obtain precise motor current measurement.

A wide range of diagnostics and protection features

integrated in the DRV3233 enable a robust motor

drive system design and help eliminate the needs

of external components. The highly configurable

device response allows the device to be integrated

seamlessly into a variety of system designs.
