애플리케이션

The 1SP0350V SCALE™-2 single-channel plug-and-play gate driver reliably and safely drives 4500 V Press-Pack IEGT and IGBTs as well as other IEGT and IGBT form factors. It is ideal for high-reliability applications in the HVDC and railway industries.

Based on the SCALE-2 chipset, the 1SP0350 is a highly integrated, high performance, complete and extremely compact single-channel gate driver. The SCALE-2 chipset reduces the component count by 85% compared to conventional solutions - significantly increasing reliability and reducing costs. The driver is equipped with Dynamic Advanced Active Clamping (DAAC), short-circuit protection, a built in DC/DC converter, regulated turn-on gate driving voltage, gate-emitter monitoring and supply voltage monitoring. The plug-and-play capability of the driver allows for immediate operation after connection.
