With a maximum data rate of 100Mbit/s, 6000V impulse withstand voltage (VIOTM), and 1200V maximum repeating isolation voltage (VIORM), the STISO621 ensures faster data transmission, longer lifetime, and higher reliability than conventional optical isolators. The first release, the STISO621 dual-channel digital isolator, features two independent channels with Schmitt trigger inputs that ensure high noise immunity and keeps pulse distortion below 3ns. STISO621: a new digital isolator outperforming conventional optical isolators Ranging from dual channel to quad channel, Si86xxT isolators are available in wide body packages to accommodate the higher isolation rating associated with. Typically, the voltages in the analog and digital domains of the isolator are at different levels. This is achieved by using a modulator to transmit high frequency. In order for digital isolators to be effectively used in high speed SPI communi-cation, it is necessary for them to meet several challenging voltage and timing parameters, as illustrated in Figure 2. is safety certified by UL1577 support several insulation withstand voltages (2kVrms, 3kVrms, 3.75kVrms, 5kVrms and 5.7kVrms), while The data rate up to 150Mbps,can be applicated at Industrial automation s.
ST's digital isolators leverage our 6kV thick-oxide galvanic-isolation technology to transfer data between isolated domains in a variety of industrial applications, providing lifetime reliability and high-voltage protection. Digital isolators couple data across an isolation barrier. The NSi8xxx devices are high reliability digital isolator providing high electromagnetic immunity and low emissions at low power consumption.
Isolate high-speed digital signals with ST's robust, reliable and flexible digital isolated interfaces.Įxplore new ST digital isolators to transmit high-speed bit streams up to 100 Mbps over the isolation barrier for high-performance industrial applications working in harsh temperatures and system noise. The new isolator enables engineers to better protect low-voltage circuitry from high-voltage events in hybrid electric vehicle (HEV) and electric vehicle.
