DESCRIPTION  
The UTC U2076B is a dual integrated high-side power switch  
particularly designed for self-powered and bus-powered Universal Serial  
Bus (USB) applications.  
The UTC U2076B meets the requirements of the USB. The low  
on-resistance of the switch satisfies USB voltage drop requirements.  
Fault current is limited to typically 750mA, well below the UL 25VA  
safety requirement. Flag outputs are available to indicate fault  
conditions to the local USB controller. In addition, soft start can  
eliminate the momentary voltage drop which is generated on the  
upstream port that may occur when the switch is enabled in  
bus-powered applications.  
SOP-8  
This device has independent functions enable and flag, and an enable  
input is compatible with both 3.3V and 5V logic.  
The UTC U2076B includes protection circuits. Thermal shutdown  
circuit is designed to protect the device from being damaged when  
high-current loads exist. UVLO (Under-voltage lockout) is used to keep  
the device off unless there is a valid input voltage present.  
The UTC U2076B is used in application such as USB host and  
self-powered hubs, bus-powered hubs, hot plug-in power supplies and  
battery-charger circuits.
