VQFN (RGZ)-48-49 mm² 7 x 7

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.
