DRV8376 Evaluation Module
Description
The DRV8376EVM is a integrated driver IC evaluation
module for three-phase motor driver applications
and provides single-chip power stage design for
customers driving 4.5V to 65V brushless DC motors.
Along with the hardware of the DRV8376, the
TMS320F280049C microcontroller-based board has
reference software that sends necessary signals to
the DRV8376 to spin a 3-phase Brushless-DC motor.
GUIComposer software allows the user to program
settings, enable the motor to spin, and monitor the
system from fault conditions.
Get Started
