Silicon Labs SI8421AB-D-IS

容性耦合22500Vrms

Overview

Silicon Lab's family of ultra-low-power digital isolators are CMOS devices offering substantial data rate, propagation delay, power, size, reliability, and external BOM advantages when compared to legacy isolation technologies. The operating parameters of these products remain stable across wide temperature ranges throughout their service life. For ease of design, only VDD bypass capacitors are required.Data rates up to 150 Mbps are supported, and all devices achieve worstcase propagation delays of less than 10 ns. All products are safety certified by UL, CSA, and VDE and support withstand voltages of up to 2.5 kVrms. These devices are available in an 8-pin narrow-body SOIC package.Applications:• Industrial automation systems• Hybrid electric vehicles• Isolated switch mode supplies• Isolated ADC, DAC• Motor control• Power inverters• Communications systems
