The LM3526 from Texas Instruments is a dual-port USB power switch designed for host port applications, ideal for notebooks and desktop PCs requiring power for multiple ports. It provides Universal Serial Bus standard power switch and over-current protection.
Key electrical specifications include an input voltage range of 2.7V to 5.5V, a maximum switch resistance of 140 mΩ, and a nominal short circuit output current of 1A. The device features a minimum continuous load current of 500mA and a 1 ms fault flag delay to filter hot-plug events. It also includes under-voltage lockout (UVLO) and thermal shutdown protection.
This component is housed in a small SOIC-8 package, minimizing board space. It is compatible with USB 1.1 and USB 2.0 standards. The smooth turn-on feature eliminates in-rush induced voltage drops, and the dual-stage thermal protection circuit ensures individual switch protection.
Applications for the LM3526 include USB root hubs, USB monitor hubs, self-powered USB hub devices, and high-power USB devices requiring in-rush limiting. It can also serve as a general-purpose high-side switch.
