Analog Devices offers a full line of digital isolation products based on ADI's proprietary iCoupler technology employing chip-scale micro-transformers - including recently released automotive grade digital isolators.
Micro-Transformers Provide Signal and Power Isolation for Hybrid Electric Vehicles
Hybrid Electric Vehicles have gained increased popularity in recent years as consumers look for
alternative fuel vehicles to conserve energy and reduce CO2 emissions. Electric motors are more energy
efficient than conventional combustion engines running on gasoline, and they can dramatically reduce
emissions. While batteries are at the heart of HEVs, they are also the source of many barriers to adopting
HEVs because of reliability, safety, weight and cost. To overcome these barriers, battery monitoring
systems are employed to maintain longevity and safe operation of the batteries. Due to their high
operating voltage, sophisticated isolation techniques are required...Read more

Automotive Grade Digital Isolators
The ADuM120x, ADuM130x and ADuM140x families of iCoupler devices have recently achieved AEC-Q100 automotive qualification. These established families of iCoupler digital isolators are now qualified for under-the-hood operation up to 125°C. Available in 8- and 16-lead SOIC packaging with data rates up to 25 Mbps, 3.0 to 5.5V level translation and low power consumption, the ADuM120x, ADuM130x, and ADuM140x products can be used in hybrid vehicle applications such as battery monitoring, gate drive for hybrid electric motor, dc-to-ac inverters, and electronic power steering. These automotive qualified products can also be employed in all vehicle types when being used as an interface for sensor clusters.

The ADuM120x, ADuM130x and ADuM140x have 3.0 to 5.5V voltage level translation. They also meet UL, CSA, and VDE approvals with specifications at:
- Max. Working Voltage - 400 kV rms
- Isolation Rating (1 minute) - 2.5 kV rms
Continuing to build on our iCoupler portfolio, the release of the automotive grade ADuM120x, ADuM130x and ADuM140x families shows the advantages that iCoupler technology provides over optocoupler solutions. The figure below compares the ADuM140xWTRWZ iCoupler product versus a typical optocoupler solution.
