DESCRIPTION
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:
• 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–.
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
provides a CS pin for USB cable resistance
compensation and a EN pin to turn on and turn off
the device.
