2 Introduction
The MCF8315 is a 4.5-V to 35-V, 5-A peak integrated three-phase gate driver IC with sensorless field-oriented
control for motor drive applications. It provides three accurately trimmed and temperature compensated half-
bridge MOSFETS, gate drivers, charge pump, current sense amplifier, linear regulator for the external load
and adjustable buck regulator. The I2C interface variant (MCF8315) also provides a standard I2C interface for
configuring the various device settings and reading fault diagnostic information through an external controller.
The MCF8315EVM 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 MCF8315. It can also provide
SPI communication for the SPI variant of the MCF8315 device. There are many user-selectable jumpers,
resistors, connectors, and test points to evaluate many features of the device and configure device-specific
settings.
This document serves as a startup guide to supplement the MCF8315EVM. It is intended for engineers to
design, implement, and validate reference hardware for the MCF8315 device.
