Quad-channel digital isolators

  • 05-Apr-2010 08:57 EDT

Analog Devices (ADI) develops quad-channel digital isolators with integrated, isolated power. The ADuM540xW digital isolators use ADI's iCoupler chip-scale micro-transformer technology, which has been deployed in more than 300 million channels of isolation shipped for a wide array of applications including automotive. The digital isolators incorporate ADI’s isoPower integrated, isolated dc-to-dc converter technology, which provides up to 500 mW of regulated, isolated power at 5-V output. In a hybrid-electric vehicle application, this level of integrated isolation allows for power to be transferred across an isolation barrier, ensuring monitoring of the battery without drawing from the battery’s power. The ADuM540xW device's small 10 x 10-mm (0.4 x 0.4-in) surface-mount packages reduce the component count of discrete solutions to a single component, reducing board space by up to 70% and cutting costs by as much as 50%, claims the company.
