Microchip dsPIC® DSC-Based Integrated Motor Drivers

Plenty of functionality packed into a single package

Microchip's dsPIC® DSC-based integrated motor drivers incorporate a dsPIC33 DSC, 3-phase MOSFET gate driver and optional LIN or CAN FD communication transceiver into to a single package.

Their dsPIC Digital Signal Controller (DSC)-based integrated motor drivers offer a combination of real-time processing with a full-bridge MOSFET gate driver for developing three-phase Brushless DC (BLDC) and Permanent Magnet Synchronous Motor (PMSM) motor control applications.

These Microchip drivers 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 dsPIC33 DSC, which eliminates the need for an external LDO. Some devices also include a CAN/CAN FD or LIN transceiver. Operating at between 70 MHz and 100 MHz, these high-performance DSCs support Field-Oriented Control (FOC) algorithms.

The dsPIC® motor drivers reduce board space and costs, making them an excellent choice for real-time embedded automotive, industrial and consumer motor control applications.

Features
