Chapter 1. Introduction
The dsPICDEM™ MCLV-2 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 Control-
lers (DSCs) and Microcontrollers (MCUs). The dsPICDEM MCLV-2 Development
Board is essentially a backwardly-compatible upgraded version of the dsPICDEM
MCLV Development Board.
The dsPICDEM MCLV-2 Development Board supports the dsPIC33F, PIC24F,
dsPIC33E, and PIC24E motor control device families. It offers a mounting option to
connect 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-2 DEVELOPMENT BOARD
shows a simplified block diagram of the dsPICDEM MCLV-2 Development
Board. The board includes various circuitry to perform the following functions:
• Drive a three-phase inverter that powers the motor phase windings
• Measure feedback signals (e.g., voltage and phase currents) and provide a
suitable fault signal
• Interface with Hall sensor or quadrature encoder for sensor-based commutation
• Communicate with a host computer or an external device via CAN, LIN, USB, or
RS-232 interface
The 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.
