CHANDLER, Ariz. – Microchip Technology Inc . (NASDAQ:MCHP), a global provider of smart, connected, and secure embedded control solutions, has announced the release of a new family of dsPIC® Digital Signal Controllers (DSC) with integrated motor drivers.
These devices are designed to streamline the development of embedded motor control systems, especially in applications where space is at a premium.
The integrated motor drivers combine a dsPIC33 DSC, a three-phase MOSFET gate driver, and an optional LIN or CAN FD transceiver into a single package. This integration aims to reduce the number of components required, minimize the printed circuit board (PCB) size, and simplify overall system design.
Joe Thomsen, Vice President of Microchip's digital signal controllers business unit, highlighted that the integration of multiple functions into one chip can cut system-level costs and save on board space, addressing the evolving needs of automotive, consumer, and industrial designs for higher performance in smaller footprints.
The new motor drivers support a single power supply of up to 29V for operation and can handle transient voltages up to 40V. An internal 3.3V low dropout (LDO) voltage regulator is included, negating the need for an external LDO.
The devices operate between 70–100 MHz, enabling high CPU performance and efficient deployment of advanced motor control algorithms like field-oriented control (FOC).
Microchip is supporting these devices with a range of development tools, including the motorBench® Development Suite V2.45, which offers a graphical user interface for FOC development. The suite's latest version introduces a zero-speed/maximum torque feature, which allows for sensorless operation while optimizing torque output at startup and low speeds.
Additionally, two new development boards, the dsPIC33CK Motor Control Starter Kit (MCSK) and the MCLV-48V-300W, provide flexible prototyping options for a variety of motor types and power levels.
Microchip's portfolio of motor control reference designs has also expanded to include solutions for automotive cooling fans, low-voltage ceiling fans, and drone propeller controllers, among others. These designs are intended to reduce time to market by offering production-ready solutions complete with schematics, bill of materials, user guides, and source code.
The announcement is based on a press release statement from Microchip Technology Inc.
