Isolated I2C Isolator
NSi810x devices are high reliability bidirectional isolators that are compatible with I2C interface. The NSi810x devices are safety certified by UL1577 support several insulation withstand voltages (3.75kVrms, 5kVrms), while providing high electromagnetic immunity and low emissions at low power consumption. The I2C clock of the NSi810x is up to 2MHz, and the common-mode transient immunity (CMTI) is up to 150kV/us. Wide supply voltage of the NSi810x device support to connect with most digital interface directly, easy to do the level shift. High system level EMC performance enhance reliability and stability of use.
