Three Phase Pre-Driver with Dual Current Shunt Amplifiers and Buck Regulator –

Hardware Controlled

Check for Samples: DRV8302

FEATURES

DESCRIPTION

The DRV8302 is a gate driver IC for three phase

motor drive applications. It provides three half bridge

drivers, each capable of driving two N-type

MOSFETs, one for the high-side and one for the low

side. It supports up to 2.3A sink and 1.7A source

peak current capability and only needs a single power

supply with a wide range from 8 to 60V. The

DRV8302 uses bootstrap gate drivers with trickle

charge circuitry to support 100% duty cycle. The gate

driver uses automatic hand shaking when high side

FET or low side FET is switching to prevent current

shoot through. Vds of FETs is sensed to protect

external power stage during overcurrent conditions.

•

Operating Supply Voltage 8V–60V

2.3A Sink and 1.7A Source Gate Drive Current

Capability

•

Integrated Dual Shunt Current Amplifiers With

Adjustable Gain and Offset

Integrated Buck Converter to Support up to

1.5A External Load

•

Independent Control of 3 or 6 PWM Inputs

Bootstrap Gate Driver With 100% Duty Cycle

Support

•

Programmable Dead Time to Protect External

FETs from Shoot Through

The DRV8302 includes two current shunt amplifiers

for accurate current measurement. The current

amplifiers support bi-directional current sensing and

provide an adjustable output offset of up to 3V.

Programmable Overcurrent Protection of

External MOSFETs

Thermally Enhanced 56-Pin TSSOP Pad Down

DCA Package

The DRV8302 also has an integrated switching mode

buck converter with adjustable output and switching

frequency to support MCU or additional system power

needs. The buck is capable to drive up to 1.5A load.
