LM3544 Datasheet - National Semiconductor

LM3544 Quad Port USB Power Distribution Switch and Over-Current Protection

The LM3544 is a quad high-side power switch that is an excellent choice for use in Root, Self-Powered and BusPowered USB (Universal Serial Bus) Hubs. Independent port enables, flag signals to alert USB controllers of error conditions, controlled start-up in hot-plug events, and short circuit protect.

LM3544 Features

* of the LM3544 include current foldback to reduce power consumption in current overload conditions, thermal shutdown to prevent device failure caused by highcurrent overheating, and undervoltage lockout to keep switches from operating if the input voltage is below acceptable levels.
