Microchip Know-how has launched a brand new household of dsPIC digital sign controller-based built-in motor drivers. These gadgets incorporate a dsPIC33 digital sign controller (DSC), a three-phase MOSFET gate driver and optionally available LIN or CAN FD transceiver into one bundle.
This integration is designed to scale back the part depend of a motor management system design, and permit smaller printed circuit board (PCB) dimensions. The gadgets are supported by improvement boards, reference designs and software notes, and shall be included in Microchip’s field-oriented management (FOC) software program improvement suite, the motorBench Improvement Suite.
The built-in motor driver gadgets could be powered by a single energy provide as much as 29 V (operation) and 40 V (transient). An inner 3.3 V low dropout (LDO) voltage regulator powers the dsPIC DSC, which eliminates the necessity for an exterior LDO to energy the system. Working between 70 and 100 MHz, the dsPIC DSC-based built-in motor drivers present excessive CPU efficiency, and might assist environment friendly deployment of FOC and different motor management algorithms.
WATCH: Vijay Bapu, Microchip Applied sciences Product Supervisor, chats with Charged at APEC 2024 about its 11 kW Totem-Pole PFC Improvement System:
Microchip gives an in depth ecosystem of motor management software program and {hardware} improvement instruments to assist make the design course of quicker and scale back the shopper’s time to market. These embody the dsPIC33CK Motor Management Starter Equipment and the MCLV-48V-300W, two new built-in motor driver improvement boards that present speedy prototyping options; and the motorBench Improvement Suite, a free GUI-based software program improvement software that measures essential motor parameters, tunes suggestions management positive factors and generates supply code utilizing the motor management software framework (MCAF).
“Automotive, client and industrial designs are evolving, and require larger efficiency and lowered footprints,” stated Joe Thomsen, VP of Microchip’s digital sign controllers enterprise unit. “These expectations usually come at a better expense and enhance in dimensional measurement. By integrating a number of system features into one chip, the dsPIC DSC-based built-in motor drivers can scale back system-level prices and board house.”
