Table of Contents EVM User's Guide: MCT8317EVM MCT8317EVM Evaluation Module ABSTRACT This document is provided with the MCT8317 customer evaluation module (EVM) as a supplement to the MCT8317x data sheet (MCT8317 Three-Phase Sensorless-Trapezoidal BLDC Motor Driver). This User's Guide details the hardware implementation of the EVM and how to setup and power the board. -
Page 2: Introduction
2 Introduction The MCT8317 is a 4.5-V to 20-V, 5-A peak integrated three-phase gate driver IC with sensorless trapezoidal for motor drive applications. It provides three accurately trimmed and temperature compensated half-bridge MOSFETS, gate drivers, charge pump, current sense amplifier, linear regulator for the external load and adjustable buck regulator. -

Optionally, use the GUI (as shown in Section 6) to monitor real-time speed of the motor, put the MCT8317 into a low-power sleep mode, and read status of the LEDs. Figure 3-1. Reference for Quick Start Guide 4 Hardware and Software Overview 4.1 Hardware Connections Overview –... -
Page 4: Connection Details
The three phases of the BLDC motor connect directly to the A, B, and C terminals of the screw terminal connector J8 provided on the MCT8317EVM.

Finally, a shunt jumper bridge on the 32-pin connector J6 ties all signals between the microcontroller and MCT8317. These jumpers can be inserted or removed as needed in order to isolate the microcontroller from the gate driver. This allows for microcontroller signal debugging or using the MCT8317EVM as a standalone gate driver with an external microcontroller. -

Page 9: Hardware Setup
The MCT8317EVM includes a USB-UART interface, using a MSP430FR2355 microcontroller, that serves as a communication bridge between a host PC and the MCT8317 device for configuring various device settings and reading fault diagnostic information. A MCT8317A GUI is available to interface with and configure the MCT8317 using this communication interface. -
