Product Summary

The LM3526MX-H 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 PCs that supply power to more than one port. The LM3526MX-H accepts an input voltage between 2.7V and 5.5V allowing use as a device-based in-rush current limiter for 3.3V USB peripherals, as well as Root and Self-Powered Hubs at 5.5V.
