Microchip launches dsPIC DSC-based integrated motor drivers

Microchip Technology has launched a new family of dsPIC Digital Signal Controller (DSC)-based integrated motor drivers, to implement efficient, real-time embedded motor control systems in space constrained applications.

These devices incorporate a dsPIC33 digital signal controller (DSC), a three-phase MOSFET gate driver and optional LIN or CAN FD transceiver into one package.

A significant benefit of this integration is reduction in component count of the motor control system design, smaller printed circuit board (PCB) dimensions and reduced complexity.

The devices are supported by development boards, reference designs, application notes and Microchip’s field-oriented control (FOC) software development suite, motorBench Development Suite V2.45.

The integrated motor driver devices can be powered by a single power supply up to 29V (operation) and 40V (transient). An internal 3.3V low dropout (LDO) voltage regulator powers the dsPIC DSC, which eliminates the need for an external LDO to power the device. Operating between 70—100 MHz, the dsPIC DSC-based integrated motor drivers provide high CPU performance and can support efficient deployment of FOC and other advanced motor control algorithms.

An extensive ecosystem of motor control software and hardware development tools are available to customers to help make the design process faster and easier, reducing time to market.

The dsPIC33CK Motor Control Starter Kit (MCSK) and the MCLV-48V-300W are two new dsPIC33-based integrated motor driver development boards that provide rapid prototyping solutions with flexible control options.

The motorBench Development Suite is a free GUI-based software development tool for FOC that accurately measures critical motor parameters, automatically tunes feedback control gains and generates source code by utilizing the motor control application framework (MCAF).
