Analog Devices introduces isolation technology that maximizes power efficiency and minimizes radiation when migrating to Industry 4.0

     Industry 4.0 technology leader Analog Devices has released a simple power solution that maximizes the efficiency of motion systems and minimizes their electromagnetic (EM) radiation as customers migrate to higher density automation. The ADUM4122 is an isolated dual-drive strength output driver with iCoupler technology that allows designers to take full advantage of more efficient power switching technology.

     According to the International Energy Agency, motor drive systems consume 40% of the world's electricity consumption, and improvements in motor efficiency will bring widespread economic and environmental benefits. As the adoption rate of industrial automation and iot in smart factories continues to increase, more smart technologies and features need to be incorporated into the system to ensure maximum efficiency. The ADUM4122 is the first simple solution to achieve this by controlling the current of the motor in operation by controlling the MOSFET or IGBT at the speed at which the user commands it to turn on or off.

     "Flexibility and efficiency are the two keys to a secure, connected enterprise. "Previously, typical solutions opted for grid-level driver strength to ensure EM system compliance at all points of operation, which meant that systems were often over-designed and under-utilized." Mack Lund, Director of Interface and Isolation Technologies at Analog Devices, said, "Users can now dynamically transition from slower to faster switches to optimize EM radiation without sacrificing efficiency. In short, when you try to reduce radiation and power consumption, you no longer need to sacrifice performance."

     The new ADUM4122 is a simple dual-drive strength output driver that efficiently switches between two piezoswing rates controlled by digital signals. Compared to today's discrete solutions with 20 or more pins or complex integrated solutions, the ADUM4122 is smaller with only 8 pins and can be used in a wide range of operating conditions. The ADUM4122 further improves system functionality with high common-mode transient suppression and low propagation delay for high-performance applications such as motion control, robotics and energy.
