Overview

The Multi-Phase Power Board is a driver board designed for 3-phase BLDC motors with or without Hall sensors. The board supports up to 4 individual phases making it well suited for stepper motors as well.

The Multi-Phase Power Board is fully supported by MCC Melody and MPLAB and software drivers for sinusoidal and trapezoidal BLDC with and without Hall Sensors are available for select microcontrollers.

The Multi-Phases Power Board needs a Curiosity Nano development board and an adapter board. 

A full solution for the AVR16EB32 requires the following three development kits:

  • Power stage for motor control
  • Board to board connector for Multi-Phase Power Board Adapters
  • Wide voltage range
    • Supports 6V-50V external power input
    • Rated for 10A at 24V
  • Four output phases
    • Individually controllable
    • MIC4605 half bridge mosfet driver
    • Voltage feedback from each phase
  • User configurable virtual point
  • Two current sense channels
    • User configurable phase selection
    • Using MCP6021 Operational amplifiers
  • On-Board Peripherals
    • MCP9701 temperature sensor
    • Potentiometer
    • User LED and push button
    • Optional external PWM input
    • Optional HALL sensor input
  • Board identification in MPLAB X IDE
  • On-board Power Supplies 
    • MIC28512 5V 2A Synchronous buck regulator, steps down input voltage
    • MCP1754 3.3V 150 mA LDO to power connected adapter, peripherals and I/O
    • MCP1661 12V 200 mA PWM Boost Regulator powering the MOSFET drivers
  • Multi-Phases Power Board
