Quad-Channel Digital Isolators with

Integrated DC to DC Converter

Datasheet (EN) 1.1

Product Overview

Safety Regulatory Approvals

The NSiP884x devices are quad-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 NSiP884x device is safety certified

by UL1577 support 4.5kVrms withstand voltages, while

providing high electromagnetic immunity and low

emissions. The data rate of the NSiP884x is up to 150Mbps,

and the common-mode transient immunity (CMTI) is up to

150kV/us. The NSiP884x 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.
