The DRV8320RS is a gate driver IC for three phase motor drive applications. It provides three high-accuracy trimmed and temperature-compensated half bridge drivers, each capable of driving a high-side and low-side N-type MOSFET.

The DRV8320RS uses SPI to provide detailed fault reporting and flexible parameter settings such as current control options for slew rate control of the gate drivers and various protection features.

BOOSTXL-DRV8320RS has been designed to work with the LAUNCHXL-F280049C LaunchPad. The C2000™Piccolo™TMS320F280049C has integrated programmable gain amplifiers (PGA), which allow for a low cost method of current sensing. This completely eliminates the need for external op-amps.

A full suite of software for evaluation of the DRV8320RS, F28004xC and InstaSPIN™-FOC can be found in the C2000Ware MotorControl SDK.
