Page 2: Cautions And Warnings
This document serves as a startup guide to supplement the MCT8329EVM. The user's guide is intended for engineers to design, implement, and validate reference hardware for the MCT8329 device. -
Page 3: Quick Start Guide
Quick Start Guide 3 Quick Start Guide The MCT8329EVM requires a power supply source, which has a recommended operating range from a 4.5-V to 60-V. To setup and power the EVM, follow the sequence below: 1. Connect motor phases to A, B, C on connector J11. -
Page 4: Hardware And Software Overview
MCT8329EVM evaluation module. The MCT8329EVM is designed for an input supply from 4.5-V to 60-V. The MCT8329EVM includes power stage with six external N-channel power MOSFETs (Part number: CSD18536KTTT) and passive components. The MCT8329EVM also includes a current sense shunt resistor of 1 mΩ... -
Page 5: Connection Details
4.2 Connection Details Figure 4-2 shows the connections made to the MCT8329EVM to spin a 3-phase sensorless Brushless-DC motor. An 4.5-V to 60-V power supply is connected to the PVDD and GND terminals on connector J10. The three phases of the BLDC motor connect directly to the A, B, and C terminals of the screw terminal connector J11 provided on the MCT8329EVM. -
Page 6: Msp430Fr2355 Microcontroller & User Interface
Finally, a shunt jumper bridge on the 32-pin connector J9 ties all signals between the microcontroller and MCT8329. 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 MCT8329EVM as a standalone gate driver with an external microcontroller. -
Page 7: Led Lights
4.4 LED Lights The MCT8329EVM has 5 status LEDs implemented that provide the status of power supplies and functions of the evaluation module. By default, the VM LED and 3.3 V Buck LEDs light up when the board is powered and the program has been flashed onto the microcontroller. -
Page 8: User-Configurable Settings
Hardware and Software Overview www.ti.com 4.5 User-Configurable Settings The MCT8329EVM includes a variety of user-selectable jumpers, switches, and resistors on the entirety of the evaluation board to configure settings. Table 4-2 summarizes all of these configurable settings. Table 4-2. Description of User-Selectable Settings on MCT8329EVM (Default in Bold) - Page 9 Hardware and Software Overview Table 4-2.
