DRV10963 Evaluation Module

This document is provided with the DRV10963 customer evaluation module (EVM) as a supplement to the
DRV10963 datasheet (

SLAS955

A). It details the hardware implementation of the EVM and gives a step-

by-step introduction to the device operation and tuning process using DRV10963 GUI.
