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.
