MCT8316AEVM Evaluation Module

ABSTRACT

This document is provided with the MCT8316A customer evaluation module (EVM) as a supplement to the 
MCT8316A data sheet (

MCT8316A Three-Phase Sensorless Trapezoidal Control BLDC Motor Driver

). This 

User's Guide details the hardware implementation of the EVM and how to setup and power the board.
