Digital Isolator NOVOSENSE NSI8222N1-DSPR Featuring 250kV per Microsecond CMTI and UL1577 Certification
Product Overview
The NSi822x devices are high reliability dual-channel digital isolators. They are safety certified by UL1577 and support several insulation withstand voltages (3.75kVrms, 5kVrms), while providing high electromagnetic immunity and low emissions at low power consumption. The data rate of the NSi822x is up to 150Mbps, and the common-mode transient immunity (CMTI) is up to 250kV/us. The NSi822x device provides digital channel direction configuration and the default output level configuration when the input power is lost. Wide supply voltage support allows direct connection with most digital interfaces, facilitating level shifting. High system-level EMC performance enhances reliability and stability. An AEC-Q100 (Grade 1) option is available for all devices.
