LM3525  
Single Port USB Power Switch and Over-Current  
Protection  
General Description  
Features  
n Compatible with USB1.1 and USB 2.0  
The LM3525 provides Universal Serial Bus standard power  
switch and over-current protection for all host port applica-  
tions. The single port device is ideal for Notebook PC and  
Handheld PC applications that supply power to one port.  
n 1 ms Fault Flag Delay During Hot-Plug Events  
n Smooth Turn-On Eliminates Inrush Induced Voltage  
Drop  
A 1 ms delay on fault flag output prevents erroneous over-  
current reporting caused by inrush currents during the hot-  
plug events.  
n UL Recognized Component: REF # 205202  
n 1A Nominal Short Circuit Output Current Protects  
Notebook PC Power Supplies  
The LM3525 accepts an input voltage between 2.7V 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 3.3V and 5.0V  
logic thresholds.  
n Thermal Shutdown Protects Device in Direct Short  
Condition  
n 500mA Minimum Continuous Load Current  
n Small SO-8 Package Minimizes Board Space  
n 2.7V to 5.5V Input Voltage Range  
n Switch Resistance 120 mMax. at VIN = 5V  
n 1µA Max Standby Current  
The small size, low RON, and 1 ms fault flag delay make the  
LM3525 a good choice for root hubs as well as ganged  
power control in space-critical self-powered hubs.  
n 100 µA Max Operating Current  
n Undervoltage Lockout (UVLO)  
Applications  
n Universal Serial Bus (USB) Root Hubs including  
Desktop and Notebook PC  
n USB Monitor Hubs  
n Other Self-Powered USB Hub Devices  
n High Power USB Devices Requiring Inrush Limiting  
n General Purpose High Side Switch Applications
