NSi822x-Q1
High Reliability
Dual-Channel Digital Isolators
Datasheet (EN) 1.1
Product Overview
Safety Regulatory Approvals
The NSi822x devices are high reliability dual-channel
digital isolators. The NSi822x device is safety certified by
UL1577 support several insulation withstand voltages
UL recognition: up to 5000Vrms for 1 minute per UL1577
CQC certification per GB4943.1-2011
CSA component notice 5A
(3.75kVrms,
5kVrms),
while
providing
high
electromagnetic immunity and low emissions at low
power consumption. The data rate of the NSi822x is up
to 150Mbps, and the common-mode Transient immunity
(CMTI) is up to 250kV/us. The NSi822x device provides
digital channel direction configuration and the default
output level configuration when the input power is lost.
Wide supply voltage of the NSi822x device support to
connect with most digital interface directly, easy to do
the level shift. High system level EMC performance
enhance reliability and stability of use. AEC-Q100 (Grade
1) option is provided for all devices.
