3 Description
The TPS2511 device 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 dedicated
charging schemes:
1. Divider DCP, required to apply 2.7 V and 2 V on
the D+ and D– lines respectively or 2 V and 2.7 V
on the D+ and D– lines respectively
2. BC1.2 DCP, required to short the D+ line to the
D– line
3. 1.2 V on both D+ and D– lines
The TPS2511 is a 70-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 3.8 V (typical) or
when an overtemperature protection occurs during an
overload condition. Accurate and programmable
current limit provides flexibility and convenience for
applications. The TPS2511 provides a CS pin for
USB cable resistance compensation and an EN pin to
control the device turnon and turnoff.

DESCRIPTION
Active-low, open-drain output. When OUT current is more than approximately half of the
current limit set by a resistor on ILIM_SET pin, the output is active low. Maximum sink
current is 10 mA.
Connected to the D– or D+ line of USB connector. Provide the correct voltage with an
attached portable equipment for DCP detection, high impedance while disabled.
Connected to the D+ or D– line of USB connector. Provide the correct voltage with an
attached portable equipment for DCP detection, high impedance while disabled.
Logic-level control input. When it is high, turns power switch on, when it is low, turns power
switch off and turns DP and DM into the high impedance state.
Ground connection.
External resistor used to set current limiting Threshold. TI recommends 16.9 kΩ RILIM_SET
750 kΩ.
Power supply input voltage connected to the power switch. Connect a ceramic capacitor with
a value of 0.1-µF or greater from the IN pin to GND as close to the device as possible.
Power-switch output. Connect to VBUS of USB
Ground connection.
