NSI66x1A
Single-Channel Isolated Smart Gate Driver
Datasheet (EN) 1.1
Product Overview
Applications
The NSI66x1A is a single channel reinforced isolated
smart gate driver to drive IGBTs and SiC MOSFETs inf
many applications. It can source and sink 10A peak
current. System robustness is supported by 150kV/us
minimum common-mode transient immunity (CMTI).
The NSI66x1A includes crucial protection features such
as miller clamp, DESAT, UVLO and soft turn off. UVLO and
short circuit fault are reported through separate pins.
ASC feature is designed to force output on in emergency,
which supports system fault management.
