3 Description

The DRV8363-Q1 is an integrated smart gate driver

for 48V automotive three-phase BLDC applications.

The device provides three half-bridge gate drivers,

each capable of driving high-side and low-side

N-channel power MOSFETs. The DRV8363-Q1

generates the correct gate drive voltages using an

external 12V supply and an integrated bootstrap diode

for the high-side MOSFETs. The Smart Gate Drive

architecture supports configurable peak gate drive

current from 16mA up to 1A source and 2A sink. The

DRV8363-Q1 can operate with a wide input range

from 8V to 85V at the motor connection. A trickle

charge pump allows for the gate drivers to support

100% PWM duty cycle control and provides overdrive

gate drive voltage of external switches.

The DRV8363-Q1 provides low-side current sense

amplifiers to support resistor based low-side

current sensing. The low offset of the amplifiers

enables the system to obtain precise motor current

measurements.

A wide range of diagnostics and protection features

are integrated with the DRV8363-Q1 enables a robust

motor drive system design and helps eliminate the

need of external components. The highly configurable

device response allows the device to be integrated

seamlessly into a variety of system designs.
