LM3525M-L

TEXAS INSTRUMENTS  LM3525M-L  电源开关, USB, 过流保护, 高压侧, 低电平有效, 2路输出, 5.5V, 1A, SOIC-8

The is a single port USB Power Switch with 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 1ms delay on fault flag output prevents erroneous over-current reporting caused by inrush currents during the hot-plug events. The LM3525 accepts an input voltage between 2.7 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 3.3 and 5.0V logic thresholds. The small size, low RON and 1ms fault flag delay make this power switch a good choice for root hubs as well as ganged power control in space-critical self-powered hubs.
