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.
