NSi822xC

High Reliability

Dual-Channel Digital Isolators

Datasheet (EN) 1.3

Safety Regulatory Approvals

Product Overview



UL recognition: up to 5000V_rmsfor 1 minute per UL1577

CQC certification per GB4943.1-2022

CSA component notice 5A

The NSi822xC devices are high reliability dual-channel

digital isolators. The NSi822xC device is safety certified

by UL1577 support several insulation withstand voltages

(3.75kVrms,

5kVrms),

while

providing

high

electromagnetic immunity and low emissions at low

power consumption. The data rate of the NSi822xC is up

to 150Mbps, and the common-mode transient immunity

(CMTI) is up to 250kV/us. The NSi822xC device provides

digital channel direction configuration and the default

output level configuration when the input power is lost.

Wide supply voltage of the NSi822xC 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.

DIN EN IEC 60747-17 (VDE 0884-17)

Applications
