Function Description 7.1. Overview The NSiP882x devices are dual-channel digital isolators with integrated isolated DC-DC converter. The digital isolators are based on Novosense capacity isolation barrier technique.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 capacity isolation technology. The NSiP882x device are safety certified by UL1577 support 4.5kVrms insulation 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 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.

The NSiP882x devices are suitable for the limited PCB space applications. The devices are also suitable for wide temperature application which the most the power module can not support. 7.2. Device Functional Modes 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. Supply configuration table showed below. SEL PIN VDD VISO Shorted to VISO 5V 5V Shorted to GND2 or floating 5V 3.3V Shorted to GND2 or floating 3.3V 3.3V The NSiP882x devices provide four channel digital isolators. The digital isolators have default weak pull up or pull down input status when input is floating as shown in below table. Input VDD1 status VDDOUT status Output Comment H Ready Ready H Normal operation L Ready Ready L floating Ready Ready L(NSiP882xW0) Floating input status H(NSiP882xW1) 7.3. Emi Considerations The NSiP882x devices are using on chip transformer, so the power transfer must operate at high frequency allow higher efficiency transfer using the small transformer. This will cause emissions which need to pay attention to PCB layout if the application allow low emission. Please see the application note if needed. 7.4. Output Short And Over Temperature Protection The NSiP882x devices are protected against output short. When the devices detect the output is short, the device will be in Hiccup mode and the transfer power will be limited. So the temperature of the device will be low, and the device is protected. The NSiP882x devices are also protected against over temperature. When the devices detect the chip is over 165℃, the device will be shut down until the temperature of the device is below 145℃. 8. Application Note 8.1. Typical Application The NSiP882x requires a 0.1 µF and 10uF bypass capacitors between VDD and GND1, VISO and GND2. The capacitor should be placed as close as possible to the package. This is very important for the performance of the device. The figure 8.1 is the basic schematic of NSiP882x and the figure 8.2 is the typical isolated CAN schematic using NSiP8821.
