Microchip BLDC Motor for MCP8025

The Microchip MCP8025 Brushless DC (BLDC) Motor Gate Driver Evaluation Board is a platform designed to demonstrate the drive capabilities of the MCP8025 motor driver device. The board utilises a dsPIC33EP256MC504 processor in combination with the MC8025 to implement a stand-alone 6-step trapezoidal BLDC motor controller.

The board has a terminal block to apply the input voltage with an output header and plated PCB through-hole pads as a means to connect the external motor. Two programming headers are provided for updating the dsPIC33EP256MC504 firmware using either a PICkit programmer/debugger or a MPLAB® in-circuit debugger. Another terminal is provided to allow users to create LIN communication connections to the MCP8025 LIN transceiver.

Input operating voltage range: +6.0V to +19V
