The LM3526M-H/NOPB is a dual port USB Power Switch with 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 1ms delay on the fault flag output prevents erroneous over-current 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 excessive heat is turned off, allowing the second switch to continue to function uninterrupted. This power switch accepts an input voltage between 2.7 and 5.5V uses as a device-based in-rush current limiter for 3.3V USB peripherals, as well as Root and Self-Powered Hubs at 5.5V. The small size, low RON and 1ms fault flag delay make this power switch a good choice for root hubs as well as per-port power control in embedded and stand-alone hubs.
