ST introduces GaN driver with integrated galvanic isolation for superior safety and reliability

July 10, 2023 /SemiMedia/ — STMicroelectronics not too long ago launched the primary galvanically remoted gate driver for gallium nitride (GaN) transistors, the STGAP2GS, which reduces dimension and bill-of-materials in functions requiring wonderful wide-bandgap effectivity mixed with strong security and electrical safety .

The only-channel driver might be related to a high-voltage rail as much as 1200V, or 1700V with the STGAP2GSN narrow-body model, and gives gate-driving voltage as much as 15V. Able to sinking and sourcing as much as 3A gate present to the related GaN Transistor, the driving force ensures tightly managed switching transitions as much as excessive working frequencies.

With minimal propagation delay throughout the isolation barrier, at simply 45ns, the STGAP2GS ensures quick dynamic response. As well as, dV/dt transient immunity of ±100V/ns over the complete temperature vary guards towards undesirable transistor gate change. The STGAP2GS is out there with separate sink and supply pins for straightforward tuning of the gate-driving operation and efficiency.

Saving the necessity for discrete parts to offer optical isolation, the STGAP2GS driver eases the adoption of environment friendly and strong GaN expertise in varied shopper and industrial functions. These embody energy provides in laptop servers, factory-automation tools, motor drivers, photo voltaic and wind energy methods, house home equipment, home followers, and wi-fi chargers.

Along with integrating galvanic isolation, the driving force additionally options built-in system safety together with thermal shutdown and under-voltage lockout (UVLO) optimized for GaN expertise, to make sure reliability and ruggedness.

The STGAP2GS in SO-8 widebody package deal, and the STGAP2GSN SO-8 slender model, can be found now, priced from $1.42 for orders of 1000 items. For extra data, please go to www.st.com/stgap2gs
