1.2 MCP8063 12V 3-PHASE BLDC SENSORLESS FAN CONTROLLER
DEMONSTRATION BOARD HARDWARE DESCRIPTION
The MCP8063 12V 3-Phase BLDC Sensorless Fan Controller Demonstration Board
contains several components:
• PIC24FJ64GB002 microcontroller for USB connection, PWM generation,
FG frequency measurement, V
DD
measurement, activation of other signals and
component communication
• MCP1824 LDO regulator to provide 3.3V to the microcontroller
• MCP19110 buck regulator to provide power supply to the fan driver
• MCP3421 Delta-Sigma ADC for sensing the fan driver current consumption
