4-channel digital isolators with integrated isolated DC-DC power supplies

The NSIP894x family are 4-channel digital isolators with integrated isolated DC-DC power supplies. The isolated DC-DC power supply provides up to 500mW of output power from the on-chip transformer. The feedback PWM signal is sent to the primary side by a digital isolator based on NOVOSENSE capacitive isolation technology. Highly integrated solutions can help simplify system design and improve reliability. The product has passed UL1577 certification, supports 4500Vrms insulation voltage, while providing high EMI immunity and low radiation. The data rate of this series of products is up to 150Mbps, and the CMTI is up to 150kV/us. And provide 5V to 5V, 5V to 3.3V, 3.3V to 3.3V conversion mode, the output voltage can be set through the SEL pin.
