Product Summary

The LM3526M-L is a Dual Port USB Power Switch. The device provides Universal Serial Bus standard power switch and over-current protection for all host port applications. The dual port LM3526M-L is ideal for Notebook and desktop PC’s that supply power to more than one port. The device 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. The applications of the LM3526M-L are Universal Serial Bus (USB) Root Hubs including Desktop and Notebook PC, USB Monitor Hubs, Other Self-Powered USB Hub Devices, High Power USB Devices Requiring In-rush Limiting, General Purpose High Side Switch Applications
