DRV7308EVM Evaluation Module
Description
The DRV7308EVM is a module designed for thorough
evaluation of the DRV7308 motor driver. The device
is a 250W, 450V integrated triple GaN FET half-
bridge gate driver for motor driver applications. The
DRV7308EVM provides three 650V E-mode GaN FET
half-bridges capable of directly driving a three-phase
brushless-DC motor.
The C2000
™
LAUNCHXL-F2800137
required for this kit and is used to operate and
monitor the DRV7308 driver. PWM, fault response,
and further device control are provided by the
LAUNCHXL-F2800137 module.
Features
•
Up to 450V operating voltage with 5A peak current
drive capability
•
250W capability without the need for heat sink
