Hall-Effect-Based Current Sensor

The CA-IS23050W is a 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 0.61mΩ internal resistance, the primary copper conduction path offers low power loss and high inrush current withstand capability. The CA-IS23050W is available in a 16-pin wide-body SOIC packages. The CA-IS23050W is rated for operation at working ambient temperatures of -40°C to +125°C.
