Single-Channel SCALE™-2 Driver Core 1SC0450V and 1SC0450E

SCALE™-2 Technology, highest integration level
Flexible 4.5 kV and 6.5 kV gate drives with integrated DC/DC converter and fiber optic link


Key Benefits

Compact and reliable 4.5 kV and 6.5 kV gate drive unit enables cost effective multi-level designs and supports series as well as parallel connection of IGBTs to cover high power ratings.


Robust and cost effective single-channel gate drive solution for 4.5 kV and 6.5 kV IGBT modules. The gate current capability and DC/DC converter power of the 1SC0450V and 1SC0450E are designed to support the operation of IGBT modules in parallel, significantly reducing component count over discrete solutions, improving reliability and saving costs. Additional features, such as power supply short-circuit protection, which protects the driver in case of VISO to COM or gate-emitter short circuits, are also implemented and provide further driving benefits. A service life time of more than 15 years is guaranteed.
