To implement efficient, real-time embedded motor control systems in space-constrained applications, Microchip Technology has launched a new family of dsPIC® Digital Signal Controller (DSC)-based integrated motor drivers. These devices claim to 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 would be 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.
Automotive, consumer and industrial designs are evolving and require higher performance and reduced footprints. These expectations often come at a higher expense and increase in dimensional size claim the company.By integrating multiple device functions into one chip, the company claims the dsPIC DSC-based integrated motor drivers can reduce system-level costs and board space
The integrated motor driver devices claim to 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 potentially 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.
