3 Description
The TPS254900-Q1 device is a USB charging-port
controller and power switch with short-to-battery
protection. This feature provides protection on OUT,
DM_IN and DP_IN. These three pins withstand
voltage up to 18 V. The internal MOSFET turns off
quickly when the short-to-battery condition occurs.
Rapid turnoff is very important to protect the
upstream dc-dc converter, processor, or hub data
lines.
The TPS254900-Q1 45-mpower switch has two
selectable, adjustable current limits that support port
power management by changing to a lower current
limit when adjacent ports are experiencing heavy
loads. This is important in systems with multiple ports
and upstream power supplies with limited capacity.
The TPS254900-Q1 has a current-sense output that
is able to control an upstream supply, which allows it
to maintain 5 V at the USB port even with heavy
charging currents. This feature is important in
systems with long USB cables where significant
voltage drops can occur with fast-charging portable
devices.
A current monitor allows a system to monitor the load
current in real time by monitoring the IMON voltage.
The current monitor is very useful and can be used
for dynamic port-power management.
The TPS254900-Q1 device also provides ESD
protection capability per IEC 61000-4-2, level 4 on
DP_IN and DM_IN.

DESCRIPTION
Used for IEC protection. Typically, connect a 2.2-µF capacitor and a transient-voltage
suppressor (TVS) to ground and 5.1 kΩ to OUT.
Linear cable compensation current. Connect to divider resistor of front-end dc-dc converter.
Logic-level control input for controlling the charging mode and the signal switches; see the
Device Truth Table (TT).
Logic-level control input for controlling the charging mode and the signal switches; see the
Device Truth Table (TT).
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 and signal switches on or off. When EN is low,
the device is disabled, and the signal and power switches are OFF.
Active-low, open-drain output, asserted during overtemperature, overcurrent, and
overvoltage conditions.
Ground connection; should be connected externally to the thermal pad.
External resistor used to set the high current-limit threshold.
External resistor used to set the low current-limit threshold and the load-detection current
threshold.
This pin sources a scaled-down ratio of current through the internal FET. A resistor from this
pin to GND converts current to proportional voltage; used as an analog current monitor.
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
Logic-level control input for choosing the OUT overvoltage threshold. When OVP_SEL is low,
V(OV_OUT_LOW) is active. When OVP_SEL is high, V(OV_OUT_HIGH) is active.
Active-low open-drain output, asserted in load-detect conditions
