DRV8329AEVM User’s Guide
ABSTRACT
This document is provided with the DRV8329 customer evaluation module (EVM) as a supplement to the
DRV8329 data sheet ( DRV8329 4.5-V to 60-V 1000/2000mA 3-phase gate driver ). This User's Guide details the
implementation of the EVM and shows how to set up and power the board.
Note
The DRV8329AEVM comes automatically populated with and configured for the DRV8329A. It is also
compatible for the DRV8329B variants (see
Section 4.4.1 ), but the user will need to replace the
DRV8329A with the DRV8329B for compatibility.
