LM3525
Single Port USB Power Switch and Over-Current
Protection
General DescriptionThe LM3525 provides Universal Serial Bus standard power
switch and over-current protectionforall host port applica-
tions. The single port deviceis idealfor Notebook PC and
HandheldPC applications that supply powerto one port.1ms delayon fault flag output prevents erroneous over-
current reporting causedby inrush currents during the hot-
plug events.
The LM3525 acceptsan input voltage between 2.7V and
5.5V allowing useasa device-based inrush current limiter
for 3.3V USB peripherals,as wellas Root and Self-Powered
Hubsat 5.5V. The Enable input accepts both 3.3V and 5.0V
logic thresholds.
The small size, low RON, and1ms fault flag delay makethe
LM3525a good choicefor root hubsas wellas ganged
power controlin space-critical self-powered hubs.
Features Compatible with USB1.1 and USB2.01ms Fault Flag Delay During Hot-Plug Events Smooth Turn-On Eliminates Inrush Induced Voltage
Drop UL Recognized Component: REF# 2052021A Nominal Short Circuit Output Current Protects
Notebook PC Power Supplies Thermal Shutdown Protects Devicein Direct Short
Condition 500mA Minimum Continuous Load Current Small SO-8 Package Minimizes Board Space 2.7Vto 5.5V Input Voltage Range Switch Resistance≤ 120 mΩ Max.at VIN =5V 1µA Max Standby Current 100µA Max Operating Current Undervoltage Lockout (UVLO)
Applications Universal Serial Bus (USB) Root Hubs including
Desktop and Notebook PC USB Monitor Hubs Other Self-Powered USB Hub Devices High Power USB Devices Requiring Inrush Limiting General Purpose High Side Switch Applications
