MCF8315 evaluation module for three-phase sensorless FOC integrated MOSFET BLDC motor driver

Overview

TopologyHalf-Bridge Converter Nonisolated
Input voltage4.5-35 V

Description

The MCF8315 has three half-H-bridge integrated MOSFET drivers for sensorless FOC control of a three-phase brushless DC (BLDC) motor for 4.5-V to 35-V, 5-A peak current drive. The MCx8315 integrates a buck regulator that can support 200-mA with programmable regulated supply.This EVM includes an on-board MSP430, MSP430FR2355, which is used to interface with the MCF8315EVM GUI.

Features

  • MOTORSTUDIO GUI available with full configuration and control
  • Sensorless field-oriented control (FOC)
  • 4.5V-to-35V operation with 5A peak current drive
  • 240mΩ (high-side plus low-side) integrated MOSFETs
  • Onboard MSP430 handles connectivity with the PC and GUI

Typical applications

  • Automotive Fan and Blowers
  • Residential and Living Fans, Washer and Dishwashers Pumps, Air Purifiers and Humidifier Fans
