3 Description

The DRV8334 is an integrated smart gate driver for

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 DRV8334 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 0.7-mA up to 1-A source and 2-A sink.

The DRV8334 can operate from a single power

supply with a wide input range of 4.5 to 60-V. A trickle

charge pump allows for the gate drivers to support

100 PWM duty cycle control, and provides overdrive

gate drive voltage of external switches.

The DRV8334 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 DRV8334 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.
