Current Sensing

With the progress of factory automation in recent years as represented by “Industry 4.0” and “Made in China 2025”, factories are installing more and more control equipment. Some examples of this control equipment are general-purpose drives for controlling motors, AC servo motor drives for precise position control, and controllers for robots to automate operations worldwide.

Asahi Kasei Microdevices (AKM) developed the unique coreless current sensor IC, titled “Currentier”.
Currentier is the outcome of long experience and unique technology AKM has with compound semiconductor magnetic sensors (Hall elements), package design, and analog circuit design. 

Currentier is used in industrial and residential equipment around the world and contributes to meeting the following requirements.


  • Reducing system size (i.e. equipment size)
  • Reducing design man-hours
  • Creating a safer system
  • Improving system efficiency and providing more precise control
