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.
