Microchip Technology Inc. (Nasdaq: MCHP), a leading provider of microcontroller, mixed-signal, analog and Flash-IP solutions, today announced a motor driver that integrates three-phase gate driver, controller and communications functions into a single device, simplifying development of motor control systems and accelerating time to market.

Microchip Technology Inc. (NASDAQ: MCHP) today announced a new family of dsPIC® Digital Signal Controller (DSC)-based integrated motor drivers that efficiently implement real-time embedded motor control systems in applications that operate in constrained spaces or environments.

This new driver family integrates a dsPIC33 digital signal controller (DSC), 3-phase MOSFET gate drivers and optional LIN or CAN FD transceivers into a single package, significantly reducing the component count, printed circuit board (PCB) size and design complexity of motor control systems and is supported by development boards, reference designs, application notes and Microchip’s field-oriented control (FOC) software development suite, motorBench® Development Suite V2.45.

“As automotive, consumer and industrial product development becomes more sophisticated, the need for more powerful performance and smaller footprints is increasing,” said Joe Thomsen, vice president of Microchip’s DSC business unit. “Demand is also increasing. However, meeting these demands often comes at the cost of increased size,” he said. “The dsPIC DSC-based integrated motor driver can reduce system-level cost and board space by integrating multiple device functions into a single chip.”

The new family of integrated motor drivers can operate from a single power supply up to 29 V (normal operation) and 40 V (transient voltage) and the device's internal 3.3 V low dropout (LDO) voltage regulator supplies power to the dsPIC DSC, eliminating the need for a separate external LDO to power the device. The integrated motor drivers also feature a high-speed processor ranging from 70 MHz to 100 MHz, enabling efficient implementation of FOC and other advanced motor control algorithms.
