1 Cautions and Warnings
Observe the following cautions and warnings as printed on the EVM board.
CAUTION
Hot Surface! Contact can cause burns. Do not
touch. Please take the proper precautions when
operating.
2 Introduction
The MCT8329 is a 4.5-V to 60-V, three-phase BLDC gate driver IC with code-free sensorless Trapezoidal control
for motor drive applications. The MCT8329 provides three half-bridge gate drivers, each capable of driving
highside and low-side N-channel power MOSFETs. The device generates the correct gate drive voltages using
in internal charge pump and enhances the high-side MOSFETs using a bootstrap circuit. A trickle charge pump
is included to support 100% duty cycle. The Gate Drive architecture supports peak gate drive currents up to
1-A source and 2-A sink. The MCT8329 can operate from a single power supply and supports a wide input
supply range of 4.5 to 60 V. The I2C interface variant (MCT8329A1I) also provides a standard I2C interface for
configuring the various device settings and reading fault diagnostic information through an external controller.
The MCT8329EVM includes an onboard FTDI chip to convert USB communication from the micro-USB
connector into UART and an onboard MSP430FR2355 MCU to interface with the MCT8329. The MCT8329EVM
can also provide SPI communication for the SPI variant of the MCT8329 device. There are many user-selectable
jumpers, resistors, connectors, and test points to evaluate many features of the device and configure devicespecific settings.
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.

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.
2.
3.
4.
5.
6.
7.
8.
9.
10.
11.
Connect motor phases to A, B, C on connector J11.
Do not turn on the power supply yet. Connect motor supply to PVDD and GND on connector J10.
Select J6 to 5V_USB and J8 to 3V3COM to power MSP430 from USB power supply.
Connect the micro-USB cable into the computer.
Turn the potentiometer fully clockwise to set the motor to zero speed upon powerup.
Flip the switch S1 to the top to configure BRAKE = RUN, switch S2 to the top to configure DRVOFF = ON,
switch S3 to the bottom to configure DIR = ABC, and switch S4 to the bottom to configure to WAKE.
Flip the switch SW1 to left to configure SPEED/WAKE pin to SPEED mode and DACOUT/SOx/SPEED_ANA
pin to DACOUT mode. Note that flipping the switch SW1 to right configures SPEED/WAKE pin to WAKE
mode and DACOUT/SOx/SPEED_ANA pin to SPEED_ANA mode. When SW1 is flipped to right, switch S4
can be used to put the device in SLEEP or WAKE mode and potentiometer R47 can be used to apply analog
voltage to the DACOUT/SOx/SPEED_ANA pin.
Select J12 to leftmost position(closer to C6) to apply AVDD to VREG.
Select J13 to middle position to apply analog voltage from potentiometer R47 to SPEED/WAKE pin.
Turn on the motor power supply.
Use the potentiometer R47 to control the speed of the motor and the switches to disable the motor driver,
change the direction, or apply a brake to the motor. Optionally, use the GUI (as shown in Section 6) to
monitor real-time speed of the motor, put the MCT8329 into a low-power sleep mode, and read status of the
LEDs.

Hardware and Software Overview
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.
Figure 4-2. Connections from Motor to MCT8329EVM
Figure 4-3 MSP430FR2355 Microcontrollershows where the micro-USB cable is plugged into the MCT8329EVM
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. The 5 V from the USB
power is limited to 500 mA and the 3.3 V from the FTDI chip is limit to 30 mA. If the user wants to supply more
current to these rails, then use the 5V_SEL jumper J3 and 3V3_SEL jumper J5 to connect external power rails.

Figure 4-3. Micro-USB Connector and UART for MCT8329EVM
4.3 MSP430FR2355 Microcontroller & User Interface
The MCT8329EVM includes the MSP430FR2355 low-power MCU (as shown in Figure 4-4) to communicates via
I2C with the MCT8329.
To program the MSP430FR2355, an external MSP430 FET programmer must be connected to the Spy-Bi-Wire
(SBW) interface connector J4. Many MSP430 LaunchPad™ provide an onboard eZ-FET Debug Probe that can
be jumper-wired to the MCT8329EVM to flash the firmware into the MSP430FR2355 microcontroller.
The user can use the Reset (RST) button at any time to reset and restart the MCU program. Two active-low
LEDs, D13 and D14, can be used for debug purposes as well.
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.
