NSiP8820/NSiP8821/NSiP8822  
Dual-Channel Digital Isolators with  
Integrated DC to DC Converter  
Datasheet (EN) 1.1  
Product Overview  
Safety Regulatory Approvals  
The NSiP882x devices are dual-channel digital isolators  
with integrated isolated DC-DC converter. The isolated  
DC-DC converter provides up to 500mW output power  
using on chip transformer. The feedback PWM signal is  
sent to primary side by a digital isolator based on  
Novosense capacity isolation technology. The high  
integrated solution can help to simplify system design and  
improve reliability. The NSiP882x device is safety certified  
by UL1577 support 4.5kVrms withstand voltages, while  
providing high electromagnetic immunity and low  
emissions. The data rate of the NSiP882x is up to 150Mbps,  
and the common-mode transient immunity (CMTI) is up to  
150kV/us. The NSiP882x devices provide 5V to 5V, 5V to  
3.3V, 3.3V to 3.3V conversion mode, the output voltage  
can be set by SEL pin.The logical level of digital isolators  
on left side can be set by VDDL pin which can support the  
application when the supply voltage and I/O voltage level  
are different.  
UL recognition: up to 4500Vrms for 1 minute per UL1577  
CQC certification per GB4943.1-2011  
CSA component notice 5A  
DIN VDE V 0884-11:2017-01  
Applications  
Industrial automation system  
Isolated SPI, CAN, RS485
