Output driver aids motor efficiency

Analog Devices 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 ADuM4122 further improves system capabilities with high common-mode transient immunity and low propagation delay for high performance applications such as motion control, robotics and energy.

The EVAL-ADuM4122EBZ evaluation board supports the ADuM4122.
