Working Principles

The ACS71020KMABTR-030B3-SPI utilizes the Hall effect to measure electrical current. When a current flows through the integrated conductor, it generates a magnetic field perpendicular to the current flow. The Hall sensor within the IC detects this magnetic field and converts it into a voltage proportional to the current. This voltage is then digitized and transmitted via the SPI interface for further processing.
