Microchip MCP8025 | Demoboard ADM00600

Description

The MCP8025 TQFP BLDC Motor Driver Evaluation Board is used to demonstrate thedrive capabilities of the MCP8025. The board uses the MCP8025 3-Phase BrushlessDC (BLDC) motor gate driver and dsPIC33EP256MC504 processor to implement a6-step trapezoidal BLDC motor controller.The MCP8025 TQFP BLDC Motor Driver Evaluation Board is used to evaluateMicrochip’s MCP8025 in a BLDC motor application. As provided, the MCP8025 TQFPBLDC Motor Driver Evaluation Board is ready to operate a BLDC motor using oneon-board push button to start and stop the motor plus one on-board potentiometer toset motor speed. The evaluation board can drive a BLDC motor with a supply voltageof up to 19V and a motor current up to 15 amps. The MCP8025 TQFP BLDC MotorDriver Evaluation Board provides a 6-step trapezoidal control algorithm along with a750 mW buck converter, 5V and 12V LDO, high-to-low level voltage translators, currentsense operational amplifiers, LIN transceiver and Hall-effect inputs. The evaluationboard provides a status indication for the power supplies and the six on-boardPulse-Width Modulation (PWM) inputs.
