MCP8024 BLDC Motor Driver Evaluation Board

The BLDC Motor Driver Evaluation Board of the MCP8024 TQFP is used to demonstrate the MCP8024 drive capabilities. A total stand-alone engine operator for brushless DC motors (BLDC) is the MCP8024 TQFP BLDC Motor Driver Evaluation Board. The board is capable of riding up to 15A and 28V with a three-phase brushless DC motor. The board’s input voltage variety is between 7V and 28V. The MCP8024 on board uses internal rectifier diodes to produce 5V and 12V.

Motor gate driver MCP8024 3-Phase Brushless DC (BLDC)

The board uses the motor gate driver MCP8024 3-Phase Brushless DC (BLDC) and the plug-in module (PIM) dsPIC33FJ32MC204 to implement a 6-step BLDC motor controller. In a BLDC motor system, the MCP8024 TQFP BLDC Motor Driver Evaluation Board is being used to test the MCP8024 of Computer chip. As presented, the MCP8024 TQFP BLDC Motor Driver Evaluation Board is prepared to use one on-board toggle switch to stop and start the engine, plus one on-board potentiometer to set the engine speed. The test board will power a BLDC engine with up to 28V supply voltage and up to 15A motor current. The BLDC Motor Driver Evaluation Board MCP8024 TQFP offers a 6-step trapezoidal control dataset with a 750 mW buck converter, 5V and 12V LDO, high-to-low voltage translators, present sense operational amplifiers and Auditorium-effect inputs.The assessment board gives an impression of the designation of the power supplies and the six Pulse-Width Modulation (PWM) inputs on board.

Configuring the The MCP8024

The MCP8024 has setup registers which can be used to change the device’s operating variables. The parameters were changed using the DE2 messaging bus to transmit data to the MCP8024. The transmission bus DE2 is a half-duplex, 9600 baud, 8-bit data, 1-stop bit, 1-start bit, no parity, serial communication link. To communicate with the registers, the user can attach code to the firmware of the evaluation board. The code of the evaluation board includes a subroutine that initializes the registers of MCP8024.
