iCoupler Digital Isolator ICs for Electric-Hybrid Automotive - ADuM120xW, ADuM130xW and ADuM140xW - Analog Devices

Analog Devices (ADI) has announced the availability of company’s new iCoupler
products, the ADuM120xW, ADuM130xW and ADuM140xW digital
isolators.  The new iCoupler digital isolator devices are designed for
electric-hybrid automotive systems, and have achieved AEC-Q100
automotive qualification, a critical stress test qualification for automotive
ICs (integrated circuits) delivered by AEC (Automotive Electronics Council).

Analog Devices’ ADuM120xW, ADuM130xW and ADuM140xW iCoupler Digital Isolator ICs

The ADuM120xW (2-channels), ADuM130xW (3-channels) and ADuM140xW (4-channels)
digital isolators are based on ADI’s iCoupler chip-scale micro-transformer
technology. iCoupler digital isolators are relatively insensitive to temperature
and offers long-term reliability. Because iCoupler products have a digital
interface, there is no need for external signal conditioning components, and
they consume one-tenth to one-sixth the power of opto-couplers at comparable
signal data rates. The CMOS-based parts operate with the supply voltage on
either side ranging from 3.0 V to 5.5 V, providing compatibility with lower
voltage systems as well as enabling voltage translation across the isolation
barrier.
