The TPS2511DGN is an USB Dedicated Charging Port 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 dedicated charging schemes - Divider DCP, required to apply 2.7 and 2.0V on the D+ and D- lines respectively or 2.0 and 2.7V on the D+ and D- lines respectively, BC1.2 DCP, required to short the D+ line to D- line and 1.2V on both D+ and D- lines. The 70mR 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 3.80V (typical) or when an over-temperature protection occurs during an overload condition. Accurate and programmable current limit provides flexibility and convenience for applications.
