Transphorm and Allegro MicroSystems Team Up to Increase GaN Power System Performance for High Power Applications

Transphorm, Inc., a GaN power semiconductor manufacturer, and Allegro MicroSystems, Inc., a power and sensing semiconductor tech company, have announced a collaboration to incorporate Transphorm’s SuperGaN® FETs and Allegro’s AHV85110 Isolated Gate Driver to facilitate the expansion of GaN power system design for high power applications.
Transphorm’s SuperGaN FETs are designed to function in various topologies and are available in several different packages. This supports a wide power range and meets diverse end application requirements. These FETs are used in multiple commercial products, including higher power systems where they have been shown to significantly increase reliability, power density, and efficiency.
Allegro’s self-powered, single-channel isolated gate driver IC is optimized for driving GaN FETs in multiple applications and circuits. The AHV85110 can “enhance driver efficiency by up to 50% compared to competitive gate drivers”. This solution simplifies system design, reduces noise by 10x and common mode capacitance by 15 times compared to other market solutions.
Tushar Dhayagude, Vice President of Worldwide Sales and FAE, Transphorm, stated, “Allegro’s AHV85110 High Voltage Gate Driver provides a highly compact and efficient power stage implementation that helps to achieve an approximate 30 percent footprint reduction with the least number of external components and bias supply requirements around Transphorm’s power devices. Combined with SuperGaN’s highest reliability and superior dynamic switching performance over competing technologies, the end result is a more efficient, more robust solution with increased power density in critical applications such as server, data centers, renewables and electric vehicles.”
Vijay Mangtani, Vice President and General Manager of High Voltage Power, Allegro MicroSystems, added, “We are looking forward to the opportunity to combine our high voltage isolated gate driver AHV85110 with Transphorm’s SuperGaN FET to enable higher power density, higher efficiency, and higher power output in smaller form factors and provide value to both our and Transphorm’s customers.”
Those interested in testing the collaborative solution can do so via Allegro’s APEK85110KNH-06-T evaluation board. The board incorporates both the AHV85110 designed to work in various applications along with Transphorm’s recently announced TOLL package available in three devices with on-resistances of 35, 50, and 72 milliohms.
