Analog Devices launches isolation technology

Analog Devices has announced a power solution that maximises efficiency and minimises 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, looks to enable 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 is a dual-drive strength output driver that 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.

It also 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.
