NSiP8840/NSiP8841/NSiP8842/NSiP8843/NSiP8844 Quad-Channel Digital Isolators with Integrated DC to DC Converter Datasheet (EN) 1.1 Product Overview 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.
