Microchip MCP8025 | Demoboard ADM00600

Description

The MCP8025 TQFP BLDC Motor Driver Evaluation Board demonstrates Microchip’s 3-Phase Brushless DC (BLDC) Motor Gate Driver with Power Module, MCP8025, used in a BLDC motor drive application. When used in conjunction with a microcontroller, the MCP8025 will provide the necessary drive signals to drive for a 3-Phase BLDC motor. The MCP8025 contains the high-side and low-side drivers for external N-channel MOSFETs. A dsPIC33EP256MC504 processor is used to supply the PWM inputs to the MCP8025 as well as handle the high-speed Analog-To-Digital Conversion (ADC) required for 50 kHz PWM operation. The MCP8025 UART interface is used to configure the MCP8025 device and to send fault information to the dsPIC ® DSC controller. The evaluation board firmware uses a 6-step trapezoidal drive control algorithm to demonstrate the MCP8025 capabilities.
