New SCALE-2 plug-and-play gate drivers from Power Integrations suit a wide range of IGBT modules

This past September 20th, Power Integrations introduced the 1SP0350V SCALE-2, its single-channel +15/-10 V plug-and-play gate driver. Specifically suited to high-reliability applications in the HVDC and railway industries, the 1SP0350 gate driver reliably and safely drives 4500 V Press-Pack IGBTs and IEGTs as well as other IGBT and IEGT form factors. Based on Power Integrations’ widely used SCALE-2 chipset, the new driver is equipped with Dynamic Advanced Active Clamping (DAAC), short-circuit protection, a built in DC-DC converter, regulated turn-on gate drive voltage, DC-DC overload monitoring and supply voltage monitoring.

The new driver is not tied to any specific IGBT package style nor to a gate resistor configuration, granting designers a flexibility to test a variety of IGBT modules during development with confidence that the 1SP0350V SCALE-2 plug-and-play gate driver will function optimally. Plug-and-play capability facilitates commissioning and allows immediate operation after installation. Additionally, the highly integrated SCALE-2 chipset reduces component count by as much as 85% compared with conventional solutions, significantly increasing reliability.

The new drivers meet creepage and clearance specifications according to IEC standards (IEC61800-5-1). 1SP0350V SCALE-2 IGBT drivers are available now priced at $190 in 1,000-piece quantities.
