NSi8100  
High Reliability Bidirectional I2C Isolators  
Datasheet (EN) 2.4  
Safety Regulatory Approvals  
Product Overview  
The NSi8100 devices are high reliability bidirectional  
isolators that are compatible with I2C interface. The  
NSi8100 devices are 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 I2C clock of  
the NSi8100 is up to 2MHz, and the common-mode  
transient immunity (CMTI) is up to 150kV/us. Wide supply  
voltage of the NSi8100 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.  
UL recognition: up to 5000Vrms for 1 minute per UL1577  
CQC certification per GB4943.1-2011  
CSA component notice 5A  
DIN VDE V 0884-11:2017-01  
Applications  
Power over ethernet  
Isolated I2C, SMBus, or PMBus interface  
I2C level shifting
