NSI66x1A-Q1
Single-Channel Isolated Smart Gate Driver
Datasheet (EN) 1.1
CQC certification per GB4943.1
Product Overview
The NSI66x1A is a single-channel reinforced isolated
smart gate driver to drive IGBTs and SiC MOSFETs in
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.
Applications
Traction Inverter for EVs
On-board Charger and DC/DC Converter for HEV/EVs
UPS and Power Supplies
