BLDC/PMSM Eval Kits Pair Controller with Advanced GaN Drivers
Cambridge GaN Devices and Qorvo have partnered to create a pair of evaluation kits (EVKs) that can be used to develop efficient, cost-effective BLDC and permanent-magnet synchronous-motor (PMSM) motor-controller systems used in appliances, tools, and other applications. The easily configurable kits combine Qorvo’s PAC5556A high-performance BLDC/PMSM motor controller/driver and CGD’s easy-to-use ICeGaN ICs in a single board.
By employing CGD’s latest-generation P2 ICs, the PAC5556AEVK2 evaluation kit with 240-mΩ ICeGaN drive loads up to 400 W without a heatsink. Its higher-powered counterpart, the PAC5556AEVK3 with 55-mΩ ICeGaN is able to deliver up to 800 W of peak power with minimal airflow cooling.
ICeGaN’s efficiency gains result in reduced power loss, increased power availability, and minimized heat dissipation, enabling smaller and more reliable systems. Because CGD’s ICeGaN devices integrate essential current-sense and Miller clamp elements, the EVKs enable simpler, more compact designs with lower BOM costs.
Both the PAC5556A + CGD GaN EVKs offer higher torque at low speeds and precise control, suiting them for white goods, ceiling fans, refrigerators, compressors, and pumps. Target markets include industrial and home automation, especially where compact, high-efficiency, motor-control systems are required. PAC5556AEVK2 and PAC5556AEVK3 are now available at Qorvo’s website.
