The SI88244ED-IS is a Digital Isolator with an on-chip isolated dc-dc converter that provides regulated output voltages of 3.3 or 5V (or >5V with external components) at peak output power levels of up-to 2W. This device provides up-to four digital channels. The dc-dc converter has user-adjustable frequency for minimizing emissions, a soft-start function for safety, a shut-down option and loop compensation. The device requires only minimal passive components and a miniature transformer. The ultra-low-power digital isolation channels offer substantial data-rate, propagation delay, size and reliability advantages over legacy isolation technologies. Data rates up to 100Mbps are supported and it achieves propagation delay of only 23ns. Ordering options include a choice of dc-dc converter features, isolation channel configurations and a fail-safe mode. It is certified by UL, CSA, VDE and CQC standard.
