Infineon Unveils Quad-Channel Digital Isolators For Automotive And Industrial Applications

Infineon Applied sciences AG has expanded its ISOFACE product vary by introducing quad-channel digital isolators designed for industrial and automotive functions. With a deal with enhancing isolation applied sciences, the ISOFACE quad-channel digital isolators cater to the demanding communication necessities of contemporary digital techniques in sectors similar to automotive and industrial.

Out there in two classes, the ISOFACE 4DIRx4xxHA household is AEC-Q100 certified for automotive functions like onboard chargers, battery administration techniques, inverters, and motor management. The ISOFACE 4DIRx4xxH household is JEDEC-qualified and designed for industrial functions together with renewables, servers, telecom, industrial switch-mode energy provides, industrial automation, and remoted serial peripheral interface.

These isolators, housed in a wide-body 300 mil PG-DSO-16 package deal, characteristic 4 knowledge channels, guaranteeing strong 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) expertise equips the isolators with excessive immunity in opposition to system noise (widespread mode transient immunity of at the very least 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 situations starting from -40°C to +125°C.

Past sturdiness, these digital isolators mitigate sign noise, guaranteeing 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 obtainable, whereas the remaining two variants are anticipated in This fall 2023. For extra particulars, go to
