Datasheet	LM3525 LM3 Datasheet (PDF)

The LM3525 provides Universal Serial Bus standard power switch and over-current protection for all host port applications.

The single port device is ideal for Notebook PC and Handheld PC applications that supply power to one port.

A 1 ms delay on fault flag output prevents erroneous overcurrent reporting caused by inrush currents during the hot-plug events.
