MCT8316ZTEVM Evaluation Module
Abstract
This document is provided with the MCT8316ZT customer evaluation module (EVM) as a supplement to the MCT8316Zx data sheet (MCT8316Z Three-Phase Sensored-Trapezoidal BLDC Motor Driver Data Sheet). This User's Guide details the hardware implementation of the EVM and how to setup and power the board.
The MCT8316ZTEVM comes automatically populated with and configured for the MCT8316Z0T. It is also compatible for the MCT8316Z0R variant (see MCT8316Z0R Compatibility), but the user will need to replace the MCT8316Z0T with the MCT8316Z0R for compatibility.

2 Introduction
The MCT8316Z is a 4.5-V to 35-V, 8-A peak integrated three-phase gate driver IC with sensored trapezoidal control for motor drive applications. It provides three integrated half-bridges and a sensored trapezoidal algorithm capable of directly driving a 3-phase brushless-DC motor. The hardware interface variant (MCT8316ZT) integrates an adjustable buck regulator, protection features, and flexible parameter settings such as slew rate control and buck output voltage. See Table 3-1.
Device Name | Variant |
|---|---|
MCT8316Z0T | Buck regulator and Hardware |
MCT8316Z0R | Buck regulator and SPI |
The MCT8316ZTEVM includes an onboard FTDI chip to convert USB communication from the micro-USB connector into UART. An onboard MSP430FR2355 MCU translates the UART communication and onboard potentiometer into control signals and a variable duty cycle for the PWM input of the MCT8316Z. It can also provide SPI communication for the SPI variant of the MCT8316Z device. There are many user-selectable jumpers, resistors, connectors, and test points to evaluate the features of the device and configure device-specific settings.
This document serves as a startup guide to supplement the MCT8316ZTEVM. It is intended for engineers to design, implement, and validate reference hardware for the MCT8316ZT (H/W variant) along with the device data sheet.
