Overview
LM3526 Dual Port USB Power Switch and Over-Current Protection February 2000 LM3526 Dual Port USB Power Switch and Over-Current Protection General Description 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.
The dual stage thermal protection circuit in the LM3526 provides individual protection to each switch and the entire device.
In a short-circuit/over-current event, the switch dissipating...
