Page 4: Introduction
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. -
Page 5: Quick Start Guide
Quick Start Guide 3 Quick Start Guide The MCT8316ZTEVM requires a power supply source, which has a recommended operating range from a 4.5 V to 35 V. To setup and power the EVM, use the following the sequence: 1. Connect motor phases to A, B, and C on connector J13. -
Page 6: Hardware And Software Overview
J13 provided on the MCT8316ZTEVM. Use connector J11 on the MCT8316ZTEVM to connect single-ended digital or analog differential Hall inputs. Use HALL_PWR for Hall power and AGND for Hall ground. If connecting analog inputs from a Hall element, connect MCT8316ZTEVM Evaluation Module SNLU291B –... -

Figure 4-2. Connections from Motor to MCT8316ZTEVM Figure 4-3 shows where the micro-USB cable is plugged into the MCT8316ZTEVM to provide communication between evaluation module and GUI. The USB data and 5-V power from the USB is converted into UART data and 3.3-V power to power the MSP430FR2355 microcontroller. -
Page 8: Msp430Fr2355 Microcontroller
Finally, a shunt jumper bridge on 18-pin connector J6 ties all signals between the microcontroller and the MCT8316Z device. These jumpers can be inserted or removed as needed to isolate the microcontroller from the gate driver. This allows for microcontroller signal debugging or using the MCT8316ZTEVM as a standalone gate driver with an external microcontroller. -
Page 9: Led Lights
4.4 LED Lights The MCT8316ZTEVM has 5 status LEDs that provide the status of power supplies and functionalities of the evaluation module. By default, the VM LED and 3.3-V buck LEDs will light up when the board is powered and the program has been flashed onto the microcontroller. -
