Current Sensor ICs

High accuracy, high S/N Ratio, and the fastest response time in open-type current sensor ICs.

PRODUCTS

Asahi Kasei Microdevices, the leading company of magnetic sensors, provides long-awaited current sensor products 'Currentier' based on its accumulated experience and know-how.

'Currentier' is open-type current sensor ICs which have small package with more than 8mm of creeapage and clearance distance (compliant with UL61800-5-1), the world's highest accuracy,the highest S/N ratio, the widest measurable current range and the fastest response time (*).
With these advantages, we will offer the best current sensing solution to wide-ranging applications, such as inverter control, overcurrent detection, and electrical power detection.

* AKM's own investigation, among the open-type current sensors in the world
