Key Features
- Single-channel USB charging port controller with adjustable current threshold enabling Apple, Samsung, and USB BC1.2 device detection in one IC
- 4.5 V to 5.5 V input range covering standard USB 5 V host port supplies with built-in over-current protection threshold
- Compact 8-pin SOIC footprint allowing integration into USB hub cards and wall charger designs with minimal external passive components
Applications
TPS2511DGNR is designed for USB wall chargers, laptop USB ports, and powered hub stations that need to automatically advertise the correct charging profile to connected smartphones and tablets. Its adjustable threshold allows the host designer to set the maximum port current from 500 mA to 2.4 A without additional microcontroller intervention. Automotive USB charging sockets and industrial panel-mount USB outlets also use TPS2511DGNR to provide plug-and-charge compatibility with iOS and Android devices over a standard 5 V rail.

Frequently Asked Questions
What input voltage range does TPS2511DGNR support for USB charging port applications?
TPS2511DGNR accepts an input voltage from 4.5 V to 5.5 V, which matches the standard USB 5 V power rail with ±10% tolerance. This range ensures proper operation even when the host power supply experiences transient drops to 4.5 V under heavy load, preventing false over-current trips that would interrupt device charging.
Which USB charging standards does TPS2511DGNR support and how does it advertise the port to a connected device?
TPS2511DGNR supports USB Battery Charging specification BC1.2, Apple 2.4 A, Samsung AFC, and Divider Mode charging profiles by setting the D+ and D- voltage levels that smartphones and tablets read to determine maximum charge current. A connected iPhone, for example, reads the D+/D- levels and negotiates up to 2.4 A at 5 V, transferring up to 12 W of charging power through a single USB-A port.
How does the adjustable current threshold of TPS2511DGNR help prevent USB port damage from short circuits?
TPS2511DGNR includes an adjustable over-current threshold set by an external resistor divider on the ILIM pin. Setting the threshold to 2 A, for instance, means the IC disconnects the downstream port within 1 ms when current exceeds 2 A, protecting the 5 V rail and the host power supply from sustained short-circuit currents that would damage traces rated for less than 3 A.
For a 4-port USB hub design, how does TPS2511DGNR compare to a discrete D+/D- resistor divider approach?
A discrete D+/D- resistor divider requires 4 resistors per port (16 resistors for 4 ports) and provides only one fixed charging profile per port, missing Apple or Samsung profile detection. TPS2511DGNR integrates the profile-switching logic in a single 8-pin SOIC, reducing BOM count by at least 12 components across 4 ports and automatically adapting the D+/D- voltage to the device profile, increasing charger compatibility across more than 95% of smartphones on the market.
