Evaluation Module Overview
1 Evaluation Module Overview
1.1 Introduction
This document is provided with the MCF8329 customer evaluation module (EVM) as a supplement to the
MCF8329 data sheet. This user's guide details the hardware setup instructions, GUI installation, and usage
instructions.
Hot surface temperature
The EVM can have high surface temperatures marked by the FIRE triangular symbol on the EVM.
Avoid toughing the marked hot surface are when driving high currents to prevent potential burn
damage.

1.2 Kit Contents

Table 1-1 lists the contents of the EVM kit. Contact the Texas Instruments Product Information Center nearest to
you if any components are missing. TI highly recommends that users check the TI website at
to verify that the latest version of the related software is being used.

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.
