DRV8334 Evaluation Module

Description

The DRV8334EVM is a 30 A, 3-phase brushless DC

drive stage based on the DRV8334 gate driver for

BLDC motors.

The EVM allows quick evaluation of the DRV8334

device which spins a BLDC motor with trapezoidal

commutation and control.

Status LEDs for all power supplies as well as a

Fault LED are included for user feedback. The C2000

launchpad (LAUNCHXL-F280049C) is required for

this kit and is used to control the DRV8334 as well

as monitor and report faults.
