Microchip | DM330021-2

The DM330021-2 is a dsPICDEM MCLV-2 development board for motor control applications. This development board provides a cost-effective method of evaluating and developing sensored or sensorless brushless DC (BLDC) and permanent magnet synchronous motor control applications.

The MCLV-2 is fully backwards compatible with the original MCLV and all MC PIMs. The board is capable of controlling motors rated up to 48V and 15Amps.

Features:

• Motor Control Interfaces:
  • Three-phase inverter bridge with a power rating of 48V/15A
  • Ability to use internal OpAmps found on certain dsPIC33E devices or external OpAmps on the MCLV-2 board for current sensing
  • Hall sensors/quadrature encoder interface for sensored motor control
  • Phase voltage feedback for sensorless BLDC operation
  • DC bus current sense resistor for single shunt vector control
  • Phase current sense resistor for dual shunt vector control
  • Overcurrent protection
  • Input/output control switches
  • Potentiometer
  • LED indicator for PWM outputs
• Power Supply Connectors:
  • Auxiliary power tab “fast-on” connectors for the controller and power stage
  • 24V power input connector for the controller
  • Dedicated power input connector for the power stage
• Communication Interfaces:
  • CAN interface port
  • LIN interface port
  • UART communication via USB
  • UART communication via RS-232
• Programming Interfaces:
  • ICSP™ connector for programming a dsPIC DSC device
  • RJ11 connector for programming a dsPIC DSC device
  • ICSP connector for programming the PIC18LF2450 USB to UART bridge
  • Full Backwards Compatibility with MCLV
