Analog Devices, Inc., announced a simple power solution that maximizes efficiency and minimizes electromagnetic (EM) emissions of motion systems as customers migrate to higher density automation. The ADuM4122, an isolated, dual-drive strength output driver that uses iCoupler® technology, empowers designers to harness the benefits of higher efficiency power switch technologies.

Electric motor-driven systems account for 40% of global electricity consumption, according to the International Energy Agency, and improvements in motor efficiency can have wide-reaching economic and environmental benefits. With the increased adoption of industrial automation and IoT within smart factories, there is a growing demand for intelligent technology and features within systems to ensure maximum efficiency. The ADuM4122 is the first simple solution that accomplishes this by controlling how fast or slow a MOSFET or IGBT turns on or off by user command, on the fly, thereby controlling motor currents.

The new ADuM4122 is a simple dual-drive strength output driver that efficiently toggles between two slew rates controlled by a digital signal. Smaller than existing discrete or complex integrated solutions that have 20 or more pins, the ADuM4122 features only eight pins and works in a variety of operating conditions.
