Chipanalog CA-IS23025S Sensor IC

Chipanalog CA-IS23025S

The CA-IS23xxxS family is a series of highly accurate and cost-effective current sensor IC suitable for AC/DC current sensing in a variety of industrial, commercial, and communications systems. It features a low-offset, linear Hall sensor circuit and a copper conduction path that generates a magnetic field when current flows through it. The integrated Hall IC senses this magnetic field and converts it into a proportional voltage output, which has a positive slope proportional to the current flowing through the primary copper conduction path. The device senses current differentially, rejecting common-mode fields and improving accuracy in magnetically noisy environments. With its 1mΩ internal resistance, the primary copper conduction path offers low power loss and high inrush current withstand capability.
