STMicroelectronics Releases MasterGaN Device

STMicroelectronics has launched MasterGaN, the world-first platform embedding and a half-bridge driver based on silicon technology along with a pair of gallium-nitride (GaN) transistors. The combination will accelerate the creation of next-generation compact and efficient chargers and power adapters for consumer and industrial applications up to 400W.

STM“ST’s market-unique MasterGaN platform builds on our proven expertise and power-design skills to combine high-voltage smart-power BCD process with GaN technology, to accelerate the creation of space-saving and power-efficient products that are kinder to the environment,” said Matteo Lo Presti, Executive VP and General Manager Analog Sub-Group, STMicroelectronics.

GaN technology enables these devices to handle more power even as they become smaller, more lightweight, and more energy-efficient. These improvements will make a difference for smart phone ultra-fast chargers and wireless chargers, USB-PD compact adapters for PCs and gaming, as well as in industrial applications like solar-energy storage systems, uninterruptible power supplies, or high-end OLED TVs and server cloud.

With GaN technology and the advantages of ST’s integrated products, chargers and adapters can cut 80% of the size and 70% of the weight of ordinary silicon-based solutions.

ST is launching the new platform with MasterGaN1, which contains two GaN power transistors connected as a half-bridge with integrated high-side and low-side drivers.

MasterGaN1 is in production now, in a 9mm x 9mm GQFN package only 1mm high. Priced at $7 for orders of 1,000 units, it is available from distributors.

An evaluation board is also available to help jump-start customers’ power projects.

The MasterGaN1 contains two normally-off transistors that feature closely matched timing parameters, 10A maximum current rating, and 150mΩ on-resistance (RDS(ON)). The logic inputs are compatible with signals from 3.3V to 15V. Comprehensive protection features are also built-in, including low-side and high-side UVLO protection, interlocking, a dedicated shutdown pin, and over-temperature protection.
