3 Description
The TPS2549-Q1 device is a USB charging port
controller and power switch with a current-sense
output that is able to control an upstream supply. This
allows it to maintain 5 V at the USB port even with
heavy charging currents. This is important in systems
with long USB cables where significant voltage drops
can occur while fast-charging portable devices.
The TP2549-Q1 47-mΩ power switch has two
selectable, programmable current limits that support
port power management by providing a lower current
limit that can be used when adjacent ports are
experiencing heavy loads. This is important in
systems with multiple ports and an upstream supply
unable to provide full current to all ports
simultaneously.
The DCP_Auto scheme detects and selects the
proper D+ and D– settings to communicate with the
attached device, so that it can fast-charge at full
current. The integrated CDP detection enables up to
1.5-A fast charging of most portable devices with
simultaneous data communication.
The unique client-mode feature allows software
updates to client devices, but avoids power conflicts
by turning off the internal power switch while keeping
the data line connection.
Additionally, the TPS2549-Q1 device integrates short-
to-VBUS protection for D+ and D– to prevent damage
when D+ and/or D– unexpectedly short to VBUS. To
save space in the application, the TPS2549-Q1
device also integrates ESD protection to pass
IEC61000-4-2 without external circuitry on D+ and D–.

DESCRIPTION
Provide sink current proportional to output current. For cable compensation, connect to the
feedback divider of the up-stream voltage regulator.
Logic-level control inputs for controlling the charging mode and the signal switches; (see
Table 8-2). These pins tie directly to IN or GND without a pullup or pulldown resistor.
D– data line to downstream connector
D– data line to upstream USB host controller
D+ data line to downstream connector
D+ data line to upstream USB host controller
Logic-level control input for turning the power switch and the signal switches on/off. When
EN is low, the device is disabled, the signal and power switches are OFF.
Active-low open-drain output, asserted during overtemperature, overcurrent, and DP_IN and
DM_IN overvoltage conditions. See Table 8-1.
Ground connection; should be connected externally to the thermal pad.
Connect external resistor to ground to set the high current-limit threshold.
Connect external resistor to ground to set the low current-limit threshold and the load-
detection current threshold.
Input supply voltage; connect a 0.1 µF or greater ceramic capacitor from IN to GND as close
to the IC as possible.
Power-switch output
Active-low open-drain output, asserted when the load exceeds the load-detection threshold
Thermal pad on bottom of package. The thermal pad is internally connected to GND and is
used to heat-sink the device to the circuit board. Connect the thermal pad to the GND plane.
