Product Summary
The LM3525M-H 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 hotplug events. The LM3525M-H accepts an input voltage between 2.7V and 5.5V allowing use as a device-based inrush current limiter for 3.3V USB peripherals, as well as Root and Self-Powered Hubs at 5.5V. The Enable input accepts both 3.3V and 5.0V logic thresholds.
