–
Device HMB ESD Classification Level H2  
Device CDM ESD Classification Level C3B  
The TPS2511-Q1 is a USB dedicated charging port  
(DCP) controller and current limiting power switch. An  
auto-detect feature monitors USB data line voltage,  
and automatically provides the correct electrical  
signatures on the data lines to charge compliant  
devices among the following charging schemes:  
•
•
Supports a DCP Shorting D+ to D–  
Supports a DCP Applying 2.0 V on D+ and 2.7  
V on D– (or 2.7 V on D+ and 2.0 V on D–)  
•
•
Supports a DCP Applying 1.2 V on Data Lines  
•
Divider DCP, required to apply 2.7 V on D+ and  
2.0 V on D– or 2.0 V on D+ and 2.7 V on D–;  
BC1.2 DCP, required to short D+ to D–;  
1.2 V on both D+ and D–.  
Automatically Switch D+ and D– Lines

Hiccup Mode for Short-Circuit Protection  
Provides CS Pin for USB Cable Compensation  
Programmable Current Limit (ILIM_SET Pin)  
80-mΩ typical High-Side MOSFET  
The TPS2511-Q1 is a 80-mΩ power-distribution  
switch intended for applications where heavy  
capacitive loads and short-circuits are likely to be  
encountered. This device also provides hiccup mode  
when the output (OUT) voltage is less than 3.80 V  
typical or when an over-temperature protection  
occurs during an overload condition. Accurate and  
programmable current limit provides flexibility and  
convenience for applications. The TPS2511-Q1  
Accurate ±10% Current-Limit at 2.3 A typical  
Meets USB Power Switch Requirements
