These isolators, housed in a wide-body 300 mil PG-DSO-16 bundle, function 4 knowledge channels, making certain sturdy isolation and dependable knowledge communication in difficult environments; Working inside a voltage vary of two.7 to six.5 V, the isolators exhibit low present consumption, reaching a most of 1.6 mA per channel at speeds as much as 1 Mbps with a 3.3 V provide voltage.

Infineon’s Coreless Transformer (CT) know-how equips the isolators with excessive immunity towards system noise (frequent mode transient immunity of a minimum of 100 kV/µs) and a strong isolation voltage of as much as 5700 V rms. The isolators are constructed to resist excessive temperatures, with the automotive variants performing successfully in Grade I ambient circumstances starting from -40°C to +125°C.

Past sturdiness, these digital isolators mitigate sign noise, making certain exact timing efficiency and compatibility for top energy density designs. Pin-to-pin compatibility provides stability to energy provides, contributing to general system reliability. The isolators endure component-level and system-level certification, streamlining security approvals and expediting time-to-market.


Productive samples for six variants and starter kits are at the moment accessible, whereas the remaining two variants are anticipated in This fall 2023. For extra particulars, go to
