Qorvo Challenges TI with GaN IPM Power Modules

Cambridge GaN Devices (CGD) has announced a strategic partnership with Qorvo to develop a reference design and evaluation kit (EVK) utilizing GaN technology for motor control applications ranging from 500W to 2kW. This collaboration positions Qorvo in direct competition with Texas Instruments in the realm of intelligent power modules (IPM) using CGD's ICeGaN GaN transistors.

CGD's primary objective is to accelerate the adoption of GaN power ICs in applications involving Brushless DC (BLDC) and Permanent Magnet Synchronous Motors (PMSM). By leveraging GaN technology, these systems can achieve higher power outputs, enhanced efficiency, compact form factors, and increased reliability. Qorvo is currently developing an EVK for its PAC5556A motor control IC, which will be powered by CGD's ICeGaN H2 series devices, paving the way for a GaN-based intelligent power module (IPM).

"As they develop the module, we will provide our full support, but our main focus remains on producing top-quality GaN components," stated Peter di Maso, Vice President of Business Development at CGD, in an interview with eeNews Europe.

"The unique aspect of ICeGaN, unlike other GaN solutions available in the market, is its integration of interface circuitry without the controller alongside the GaN HEMT. This feature simplifies the integration process with highly advanced motor controller and drive ICs like Qorvo's PAC5556A 600 V High-Performance BLDC / PMSM Motor Controller and Driver," explained Giorgia Longobardi, CEO of CGD.

CGD is now setting its sights on developing a higher power variant utilizing the P2 ICeGaN transistor, which was recently launched. "Our collaboration with Qorvo on the H2 reference design has successfully combined a highly integrated 5556 motor controller with GaN technology, making it accessible to a wider audience. This development marks a significant milestone in the industry, and we are currently working on a P2 reference design with Qorvo," added di Maso.

The H2 reference design is already available, with a live demonstration taking place at the PCIM exhibition in Nuremberg, Germany this week. The EVK RD5556GaN is slated for release in Q3 2024, offering customers a practical solution for implementing GaN technology in motor control applications.
