SCALE-2 Plug-and-Play Gate Driver

Released by Power Integrations, the compact and robust SCALE-2 plug-and-play 1SP063xxxx1R gate driver is ideal for 130 x 140 mm single IGBT high-power (IHM) modules that are commonly used in railway and other long-life applications. Comprising the 1SP0630V2M1R main driver, 1SP0635D2S1R peripheral driver, and ISO6125R-33 power supply, this new device aims to streamline system development and installation. 

The new SCALE-2 plug-and-play 1SP063xxxx1R gate drivers meet IEC 61373 specifications for shock and vibration and IEC 60068-2-xx environmental requirements. Units are also EMC-qualified according to EN 50121-3-2 and IEC 6100-4-x. These gate drivers come endowed with protection features such as Dynamic Advanced Active Clamping, short-circuit, and under-voltage lock-out.

Power Integrations’ SCALE-2 technology uses an ASIC chipset to reduce component count and size, and will enable designers to optimize dynamic switching performance, accuracy and functionality and include advanced active clamping circuitry to protect the IGBT. Available to suit IHM modules from all major manufacturers like Mitsubishi, Hitachi, ABB, etc., the compact SCALE-2 gate drivers perfectly match the footprint of the smaller IHM single-channel IGBT-module formats with 1200 A to 1400 A output current and 3300 V IGBT blocking voltage.

These devices are suitable to be used in systems that require parallel modules for additional power, thus providing simplicity and flexibility in both electrical and mechanical design. With standard conformal coating, the new gate drivers can also undergo burn-in on request for added reliability. Improved connectors increase interconnection security and facilitate fast release without tooling. Fiber-optic interfaces are provided.
