Isolated Output Driver Eyes Industry 4.0 Factory Migration

Analog Devices has announced the ADuM4122, an isolated, dual-drive strength output driver that uses iCoupler technology. It’s designed to empower 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. 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.

Pricing for an ADuM4122 an 8-lead SOIC package starts at $2.53 (1,000s).
