Operating Principles At power-up, the device typically performs soft-start to reduce inrush current. The enable pin allows the system MCU to sequence power rails, while internal comparators monitor voltage and current. In normal operation, the load-switch MOSFET is fully enhanced to minimize losses; when an overcurrent or short circuit is detected, the device enters current-limiting or latch-off mode depending on severity and configuration. OVP (overvoltage protection) disconnects the load if input rises beyond safe limits, and UVP (undervoltage protection) can prevent undervoltage operation that might cause unpredictable system behavior. Thermal shutdown provides a final layer of protection by disabling outputs until the device cools.
