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

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.

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.
