FEATURES  
DESCRIPTION  
The LM3544 is a quad high-side power switch that is  
an excellent choice for use in Root, Self-Powered and  
Bus- Powered 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 protection all satisfy  
USB requirements.  
•
•
•
•
•
•
Compatible with USB1.1 and USB 2.0  
90mΩ (typ.) High-Side MOSFET Switch  
500mA Continuous Current per Port  
7 ms Fault Flag Delay Filters Hot-Plug Events  
Industry Standard Pin Order  
Short Circuit Protection with Power-Saving  
Current Foldback  
The LM3544 accepts input voltages between 2.7V  
and 5.5V. The Enable logic inputs, available in active-  
high and active-low versions, can be powered off any  
voltage in the 2.7V to 5.5V range. The LM3544 limits  
the continuous current through a single port to 1.25A  
(max.) when it is shorted to ground.

Thermal Shutdown Protection  
Undervoltage Lockout  
Recognized by UL and Nemko CB  
Input Voltage Range: 2.7V to 5.5V  
5μA Maximum Standby Supply Current  
16-Pin SOIC Package  
The low on-state resistance of the LM3544 switches  
ensures the LM3544 will satisfy USB voltage drop  
requirements, even when current through a switch  
reaches 500 mA. Thus, High-Powered USB  
Functions, Low-Powered USB functions, and Bus-  
Powered USB Hubs can all be powered off a Root or  
Self-Powered USB Hub containing the LM3544.  
Ambient Temperature Range: −40°C to 85°C  
APPLICATIONS  
•
USB Root, Self-Powered, and Bus-Powered  
Hubs  
Added features of the LM3544 include current fold-  
back to reduce power consumption in current  
overload conditions, thermal shutdown to prevent  
device failure caused by high current overheating,  
and undervoltage lockout to keep switches from  
operating if the input voltage is below acceptable  
levels.  
•
•
USB Devices such as Monitors and Printers  
General Purpose High Side Switch
