MTD6505 3-PHASE BLDC SENSORLESS FAN CONTROLLER
DEMONSTRATION BOARD HARDWARE DESCRIPTION
WHAT THE MTD6505 3-PHASE BLDC SENSORLESS FAN CONTROLLER
DEMONSTRATION BOARD KIT INCLUDES
The MTD6505 3-Phase BLDC Sensorless Fan Controller Demonstration Board
contains several components, such as:
• A microcontroller (PIC24FJ256GB) for USB connection, PWM generation, FG
• An adjustable LDO (MCP1827) combined to a digital potentiometer (MCP42050)
• The digital potentiometer is also used to set the MTD6505 R
• A Delta-Sigma (MCP3421) combined to a shunt resistor for sensing the MTD6505
