Datasheet	LM3526 LM3 Datasheet (PDF)

The LM3526 provides Universal Serial Bus standard power switch and over-current protection for all host port applications.

The dual port device is ideal for Notebook and desktop PC’s that supply power to more than one port.

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