The integrated load switching of the LS0504EVT233 provides robust, input over-current protection to the downstream circuit systems. The device comes with built-in over-voltage protection and internal soft start. The switch’s low RDS(ON) minimizes the system’s power loss.

In the event of input over-voltage, LS0504EVT233 immediately turns off the switch to prevent the downstream system from the stress of excessively high voltage. Internal soft-start ensures a smooth output voltage ramp-up and limits the input inrush current.
