THREE PHASE PRE-DRIVER WITH DUAL CURRENT SHUNT AMPLIFIERS

Check for Samples: DRV8303

FEATURES

DESCRIPTION

•

Operating Supply Voltage 6V–60V

The DRV8303 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 6V to 60V. The

DRV8303 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.

2.3A Sink and 1.7A Source Gate Drive Current

Capability

•

Integrated Dual Shunt Current Amplifiers With

Adjustable Gain and Offset

•

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

•

Slew Rate Control for EMI Reduction

Programmable Overcurrent Protection of

External MOSFETs

The DRV8303 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.

•

Support Both 3.3V and 5V Digital Interface

SPI Interface

Thermally Enhanced 48-Pin TSSOP Pad Down

DCA Package

The SPI interface provides detailed fault reporting

and flexible parameter settings such as gain options

for current shunt amplifier and slew rate control of

gate driver.
