Analog Devices launches Isolation Technology

Analog Devices has recently announced a simple power solution that maximizes efficiency and minimizes electromagnetic (EM) emissions of motion systems.

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.

Analog DeviceElectric 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.

“Flexibility and efficiency are two key tenets of a secure, connected enterprise. Previously, the typical solution was to choose a gate driver strength that would enable adherence to EM system regulations at all operating points, meaning systems were often over-engineered and under-utilized,” said Mack Lund, Director of Interface and Isolation Technology Group at Analog Devices. “Now, users can dynamically move from a slower to a faster switching transition, thus optimizing EM emissions without sacrificing efficiency. In short, you no longer have to leave performance on the table when trying to achieve lower emissions and power consumption.”

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.
