Working Principles

The AUIPS1021S operates as a high-side power switch. It utilizes MOSFET technology to control the flow of current through the load. The logic-level input signal determines the ON/OFF state of the switch. When the input is high, the switch turns on, allowing current to flow through the load. Conversely, when the input is low, the switch turns off, interrupting the current path.
