Microchip Unveils dsPIC-Based Motor Control Breakthrough

Technological Leap in Motor Control

Microchip Technology has achieved a milestone with the introduction of its new line of integrated motor controllers, leveraging the advanced dsPIC® Digital Signal Controller (DSC) technology. This breakthrough is engineered to facilitate the implementation of real-time embedded motor control systems, maximizing space efficiency in compact applications. The integration of a dsPIC33 digital signal controller, a three-phase MOSFET gate driver, and an optional LIN or CAN FD transceiver into a single package offers a cutting-edge solution for motor control system design.

Complexity and Cost Reduction

The integration’s most notable advantage is the significant reduction in the number of components required for motor control system design. This not only allows for smaller PCB dimensions but also simplifies the complexity of the design. Compatible with development boards, reference designs, application notes, and the field-oriented control (FOC) software development suite, motorBench® Development Suite V2.45, these devices provide a comprehensive solution for designers. Microchip emphasizes that advancements in automotive, consumer, and industrial designs demand higher performance in smaller sizes, which often translates to increased costs and dimensions. Microchip’s dsPIC DSC-based integrated motor driver family promises to mitigate these challenges by lowering system-level expenses and optimizing board space.

Enhanced Performance and Efficiency

Microchip’s devices can operate with a single power source ranging from 29V to 40V, powered by an integrated 3.3V low dropout (LDO) voltage regulator, eliminating the need for an external LDO. Operating within a frequency range of 70—100 MHz, the dsPIC DSC-based integrated motor drivers offer robust CPU performance, enabling the effective implementation of FOC and other advanced motor control algorithms. This technology not only promises to enhance motor control performance and efficiency but also opens new possibilities in embedded system design for automotive, consumer, and industrial applications.
