Compatible with USB1.1 and USB 2.0 power switch and over-current protection forall host
• 1 ms Fault Flag Delay During Hot-Plug Events port applications. The single port deviceis ideal for
Smooth Turn-On Eliminates Inrush Induced Notebook PC and Handheld PC applications that
Voltage Drop supply powerto one port.
UL Recognized Component: REF# 205202 A1 ms delayon fault flag output prevents erroneous
overcurrent reporting caused by inrush currents
• 1A Nominal Short Circuit Output Currentduring the hot-plug events.
Protects Notebook PC Power Supplies Thermal Shutdown Protects Devicein Direct The LM3525 accepts an input voltage between 2.7V
Short Condition and 5.5V allowing use asa device-based inrush
current limiter for 3.3V USB peripherals, as well as
• 500mA Minimum Continuous Load Current Root and Self-Powered Hubsat 5.5V. The Enable
• Small SOIC-8 Package Minimizes Board Space input accepts both 3.3V and 5.0V logic thresholds.
