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.
