DRV8328 4.5 to 60 V Three-phase BLDC Gate Driver

1 Features

3 Description

•

65-V Three Phase Half-Bridge Gate Driver

– Drives 3 High-Side and 3 Low-Side N-Channel

MOSFETs (NMOS)

– 4.5 to 60-V Operating Voltage Range

– Supports 100% PWM Duty Cycle with Trickle

Charge pump

Bootstrap based Gate Driver Architecture

– 1000-mA Maximum Peak Source Current

– 2000-mA Maximum Peak Sink Current

Hardware interface provides simple configuration

The DRV8328 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 in 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 1-A source

and 2-A sink. The DRV8328 can operate from a single

power supply and supports a wide input supply range

of 4.5 to 60 V.

•

Ultra-low power sleep mode <1 uA at 25 C̊

4-ns (typ) propagation delay matching between

phases

•

Independent driver shutdown path (DRVOFF)

65-V tolerant wake pin (nSLEEP)

Supports negative transients upto -10-V on SHx

6x and 3x PWM Modes

Supports 3.3-V, and 5-V Logic Inputs

Accurate LDO (AVDD), 3.3 V ±3%, 80 mA

Compact QFN Packages and Footprints

Adjustable VDS overcurrent threshold through

VDSLVL pin

Adjustable deadtime through DT pin

Efficient System Design With Power Blocks

Integrated Protection Features

– PVDD Undervoltage Lockout (PVDDUV)

– GVDD Undervoltage (GVDDUV)

– Bootstrap Undervoltage (BST_UV)

– Overcurrent Protection (VDS_OCP, SEN_OCP)

– Thermal Shutdown (OTSD)

The 6x and 3x PWM modes allow for simple

interfacing to controller circuits. DRV8328C and

DRV8328D variants has integrated accurate 3.3-V

LDO that can be used to power external controller

and can be used as reference for CSA. The

configuration settings for the gate driver and device

are configurable through hardware (H/W) pins.

A low-power sleep mode is provided to achieve

low quiescent current draw 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 the

nFAULT pin.
