3 Description

The DRV8329-Q1 family of devices is an integrated

gate driver for three-phase applications. The devices

provide three half-bridge gate drivers, each capable

of driving high-side and low-side N-channel power

MOSFETs. The device generates the correct gate

drive voltages using an internal charge pump and

enhances the high-side MOSFETs using a bootstrap

circuit. A trickle charge pump is included to support

100% duty cycle. The Gate Drive architecture

supports peak gate drive currents up to 1A source

and 2A sink. The DRV8329-Q1 can operate from a

single power supply and supports a wide input supply

range of 4.5 to 60V.

The 6x and 3x PWM modes allow for simple

interfacing to controller circuits. The device has

integrated accurate 3.3V LDO that can be used

to power external controller and can be used as

reference for CSA. The configuration settings for the

device are configurable through hardware (H/W) pins.

The DRV8329-Q1 devices integrate low-side current

sense amplifier that allow current sensing for sum of

current from all three phases of the drive stage.

A low-power sleep mode is provided to achieve

low quiescent current by shutting down most of

the internal circuitry. Internal protection functions

are provided for undervoltage lockout, GVDD fault,

MOSFET overcurrent, MOSFET short circuit, and

overtemperature. Fault conditions are indicated on

nFAULT pin.
