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.
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.
