Motor Control and Drive Overview

Welcome to the Motor Control and Drive design center. Here you can find solutions for your motor control project whether you are using brushed DC, stepper, brushless DC, permanent magnet synchronous, AC induction, or switched reluctance motors. You can shorten your development cycle by using free motor control software with application notes and tuning guides. Our scalable motor control development tools promote rapid prototyping for low-voltage and high-voltage systems including dual-motor control options.

Microchip offers a broad line-up of devices for motor control. These solutions range from single-chip motor control and drive solutions to low-cost 8-bit PIC® and AVR® MCUs to high-performance 16-bit dsPIC® Digital Signal Controllers (DSCs) that contain innovative motor control PWM peripherals including complementary waveforms, dedicated time bases and fast 12-bit ADCs. For applications that require variable speed with constant torque and field-oriented control for greater efficiency, the high-performance dsPIC includes DSP instructions for more precise control. For customers looking for 32-bit processing, Microchip provides a portfolio of Arm® Cortex® M0 MCUs, M4 and M7-based MCUs with floating point processing and DSP extensions as well as the 32-bit MIPS-based PIC32MK MCU series.

The single-chip motor control and motor drive solutions enable simpler designs and decrease board space, and are often used as companion chips with PIC® microcontrollers and dsPIC® digital signal controllers. To accompany a motor control MCU or DSC, Microchip provides a full line of MOSFET gate drivers from low-voltage H-bridge BDC and stepper motors up to 3-phase full bridge drivers for PMSM and BLDC motors with integrated voltage supplies and feedback circuits. MOSFET driver support for high-voltage 3-phase full bridge ACIM or BLDC/PMSM motors is also available. In addition, for low current applications Microchip offers various motor drivers with MOSFETs integrated, which include BLDC motor drivers, stepper motor drivers and multi-channel half-bridge drivers.
