MCF8329EVM 1
USB A Male-to-USB B Micro Male Cable 1
1.3 Specification
The MCF8329EVM can support voltages up to 60 V and currents up to 30 A. To prevent damage to both the IC
and the EVM, confirm that these voltage and current specifications are not exceeded.
1.4 Device Information
The MCF8329 is a 4.5-V to 60-V, three-phase brushless-DC gate driver IC with code-free sensorless field
oriented control (FOC) for motor drive applications. The device provides three half-bridge gate drivers, each
capable of driving high-side and low-side N-channel power MOSFETs. The device generates the correct gate
drive voltages using an 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 internal sensorless FOC algorithm is highly configurable through register settings in a non-volatile EEPROM
ranging from motor start-up behavior to closed loop operation, which allows for the device to operate stand-alone
once the device has been configured. Motor current is sensed using an integrated current sense amplifier
supporting a single external shunt resistor. The device can receive a speed command through a PWM input,
analog voltage, variable frequency square wave, or I2C command. There are a large number of protection
features integrated into the MCF8329, intended to protect the device, motor, and system against fault events.

2 Hardware
2.1 Quick Start Guide
The MCF8329EVM 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, and C on connector J11.
2. Do not turn on the power supply yet. Connect the motor supply to PVDD and GND on connector J10.
3. Select J6 to 5V_USB and J8 to 3V3COM to power MSP430 from USB power supply.
4. Connect the micro-USB cable into the computer.
5. Turn the potentiometer fully clockwise to set the motor to zero speed upon power up.
6. 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 WAKE.
7. 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.
8. Set J12 to leftmost position (closer to C6) to apply AVDD to VREG.
9. Set J13 to middle position to apply the analog voltage from potentiometer R47 to the SPEED/WAKE pin.
10. Turn on the motor power supply.
11. 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 3) to
monitor the real-time speed of the motor, put the MCF8329 into a low-power sleep mode, and read status of
the LEDs.

2.5 MSP430FR2355 Microcontroller
The MCF8329EVM includes a MSP430FR2355 low-power MCU, shown in Figure 2-5, to communicate via I2C
with the MCF8329 IC.
To program the MSP430FR2355, an external MSP430 FET programmer must be connected to the Spy-Bi-Wire
(SBW) interface connector J7. Many MSP430 LaunchPads™ provide an onboard eZ-FET Debug Probe that can
be jumper-wired to the MCF8329EVM to flash the firmware into the onboard MSP430FR2355 microcontroller.
The user can use the Reset (RST) button at any time to restart the MCU program. Two active-low LEDs, D13
and D14, can be used for debug purposes as well.
The 32-pin shunt jumper bridge J9 ties all signals between the microcontroller and MCF8329 IC. 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 MCF8329EVM as a standalone gate driver with an external
microcontroller.
