An accompanying suite of support tools will streamline the development of motor control systems and expedite market readiness.

Microchip Technology Inc. has launched a new family of integrated motor drivers based on its dsPIC Digital Signal Controllers (DSC). These devices integrate a dsPIC33 DSC, a three-phase MOSFET gate driver, and an optional LIN or CAN FD transceiver into a single package, offering a comprehensive solution for efficient, real-time embedded motor control in space-constrained applications.

Integrating multiple functions into one chip reduces the components required for motor control system designs, leading to smaller PCB sizes and simplified design complexity. This mainly benefits automotive, consumer, and industrial applications where high performance and compact form factors are essential.

Key features of the integrated motor driver devices include:

  • Single power supply operation up to 29V (operation) and 40V (transient)
  • Internal 3.3V low dropout (LDO) voltage regulator for the dsPIC DSC
  • Operating frequencies between 70—100 MHz, enabling high CPU performance for advanced motor control algorithms such as field-oriented control (FOC)

The company supports the development and deployment of these integrated motor drivers with a comprehensive ecosystem of software and hardware tools, including development boards, reference designs, application notes, and the motorBench® Development Suite V2.45, a free GUI-based software tool for FOC. The dsPIC33CK Motor Control Starter Kit (MCSK) and the MCLV-48V-300W development board are two new development tools that provide rapid prototyping solutions with flexible control options for various motor control applications.

Joe Thomsen, Vice President of Microchip’s Digital Signal Controllers Business Unit, emphasised the advantages of the new integrated motor drivers, stating, “By integrating multiple device functions into one chip, the dsPIC DSC-based integrated motor drivers can reduce system-level costs and board space, meeting the evolving demands for higher performance and reduced footprints in various designs.”
