Working Principles

The AUIPS1042G operates by monitoring the control input signal. When the control input is high, the device turns on the high-side power switch, allowing current flow to the load. Conversely, when the control input is low, the switch is turned off, cutting off the power supply to the load. The device continuously monitors the load current, voltage, and temperature to provide protection against faults and ensure safe operation.
