GaN-Based Motor Control Evaluation Platform

10 June 2024

Working in collaboration with Qorvo, leading specialist in advanced gallium-nitride (GaN) oriented power technology Cambridge GaN Devices (CGD) has introduced an evaluation kit (EVK) to support motor control system development activities.

This features Qorvo’s high-performance PAC5556A motor controller/driver for use with brush-less DC (BLDC) motor and permanent magnet synchronous motor (PMSM) hardware, along with CGD’s ICeGaN ICs. Capable of high-speed switching, the ICeGaN devices benefit from built-in Miller clamp and current sensing capabilities. Complementing all this, the PAC5556A integrates a 32-bit microcontroller, plus 600V gate driver and buck controller functionality. 

As Giorgia Longobardi, CGD’s CEO, explains; “Because ICeGaN - unlike other GaN implementations from other companies - integrates the interface circuitry but not the controller together with the GaN HEMT, it is simple to combine with highly integrated motor controller and drive ICs such as Qorvo’s PAC5556A 600V high=performance BLDC/PMSM motor controller and driver. We are delighted to partner with Qorvo to enable motor controller and driver applications to enjoy the benefits of GaN power.”

“Wide bandgap semiconductors such as GaN and SiC are being actively considered in various motor control applications for the power density and efficiency benefits they bring. CGD’s ICeGaN technology offers ease of use and reliability, 2 crucial factors for motor control and drive designers. We are excited to see the reaction of design engineers when they experience the power of GaN combined with our highly integrated PAC5556A 600V BLDC motor control solution,” adds Jeff Strang, General Manager of Qorvo’s Power Management Business Unit.
