OVERVIEW OF THE dsPICDEM MCLV DEVELOPMENT BOARD
FEATURES OVERVIEW
The dsPICDEM MCLV Development Board is targeted to control a Brushless DC
(BLDC) motor or Permanent Magnet Synchronous Motor (PMSM) in sensor or
sensorless operation. This flexible and cost-effective board can be configured in
different ways for use with Microchip’s specialized motor control digital signal
controllers. The dsPICDEM MCLV Development Board supports the dsPIC33F motor
control device family. It offers a mounting option to connect either a 28-pin SOIC device
or a generic 100-pin Plug-In Module (PIM). The board also has a three-phase inverter
bridge circuit. The circuit drives a BLDC or PMSM motor using different control
techniques without requiring any additional hardware. Topics covered include:
• Overview of the dsPICDEM MCLV Development Board
• Features Overview
Figure 1-1 shows a simplified block diagram of the dsPICDEM MCLV Development
Board. A dsPIC33F device uses the gate driver to drive the three-phase inverter that
powers the motor windings. The board includes various circuitry to perform the
following functions:
• Measure the feedback signals (e.g., voltage, current, Hall sensors and Fault
• Communicate with a host computer or an external device via CAN, LIN, USB or
• Drive a three-phase inverter
It also provides the option to interface Hall sensors or a Quadrature Encoder for
sensored commutation.
The dsPICDEM MCLV Development Board supports motors with terminal voltage up to
48V and current up to 15A. Refer to Appendix B. “Electrical Specifications” for
more information on electrical specifications.
