Texas Instruments TPS2513ADBVT

Overview

TPS2513ADBVT from Texas Instruments is a dual-port USB Dedicated Charging Port (DCP) controller that implements BC1.2, YD/T 1591-2009, Divider 1/2, and 1.2-V DCP detection schemes. It operates from 4.5 V to 5.5 V, delivers precise DP1/DM1 and DP2/DM2 output voltages (e.g., 2.7 V / 2.0 V in Divider 1 mode), and supports automatic data-line signature switching for fast-charging smartphones and tablets in vehicle and wall-charger applications.

For engineers reviewing the TPS2513ADBVT datasheet, TPS2513ADBVT pinout, TPS2513ADBVT application, or TPS2513ADBVT equivalent, this device enables robust, standards-compliant USB charging port design with dual-channel auto-detection, low quiescent current (200 µA max), and SOT-23-6 footprint compatibility for space-constrained AC-DC adapters and automotive USB hubs.

Technical Context

The TPS2513ADBVT integrates two independent DCP detection channels (DP1/DM1 and DP2/DM2), each capable of applying programmable voltage signatures-2.7 V/2.0 V (Divider 1), 2.0 V/2.7 V (Divider 2), 2.7 V/2.7 V (not supported), or 1.2 V/1.2 V-to USB data lines. Its auto-detect logic monitors D+ and D− line voltages to select the appropriate charging scheme without external configuration.

It features undervoltage lockout (UVLO) with 4.1 V turn-on threshold and 100 mV hysteresis, short-mode resistance ≤200 Ω between DP/DM pins, and ±10 mA continuous sink/source capability per I/O pin. All functions operate across –40°C to 125°C junction temperature with 179.9°C/W junction-to-ambient thermal resistance in SOT-23-6 package.

FAQ

What USB charging standards does the TPS2513ADBVT support?

The TPS2513ADBVT supports USB Battery Charging Specification Revision 1.2 (BC1.2), Chinese Telecommunications Industry Standard YD/T 1591-2009, Divider 1 (2.7 V/2.0 V), Divider 2 (2.0 V/2.7 V), and 1.2 V/1.2 V DCP modes. It does not support Divider 3 (2.7 V/2.7 V) or CDP/SDP enumeration. Each mode is auto-detected based on attached device behavior, and the TPS2513ADBVT applies the corresponding voltage signature to DP1/DM1 and DP2/DM2 pins without external configuration.

How does the TPS2513ADBVT handle dual-port USB charging?

The TPS2513ADBVT integrates two independent DCP channels: DP1/DM1 and DP2/DM2. Each channel monitors its respective USB data lines and applies the correct charging signature-such as 2.7 V/2.0 V for a 5-W port or 2.0 V/2.7 V for a 10-W port-based on auto-detection. This allows a single TPS2513ADBVT to manage two physically separate USB-A ports in applications like dual-outlet wall adapters or front/rear vehicle chargers without cross-talk or shared timing constraints.

What is the purpose of the IN pin on the TPS2513ADBVT?

Pin 5 (IN) is the 4.5 V to 5.5 V power supply input for the TPS2513ADBVT. It powers all internal circuitry including the auto-detect logic, voltage references, and output drivers for DP1/DM1 and DP2/DM2. A minimum 0.1 µF ceramic capacitor must be placed between IN and GND, located as close as possible to the device, to ensure stable operation and suppress supply transients during DCP signature transitions.

Can the TPS2513ADBVT be used in automotive under-hood applications?

Yes, the TPS2513ADBVT is rated for operation from –40°C to +125°C junction temperature and features robust ESD protection (±6 kV HBM on I/O pins). Its SOT-23-6 package has a junction-to-board thermal resistance of 41.9°C/W, enabling effective heat dissipation on automotive PCBs with adequate copper pour. These characteristics make it suitable for under-dash or center-console USB charging modules, though external overvoltage protection for the IN pin is recommended in 12 V vehicle systems.

What is the maximum continuous current the TPS2513ADBVT can source or sink per data line?

The TPS2513ADBVT supports ±10 mA continuous sink or source current on each of its four I/O pins (DP1, DM1, DP2, DM2), as specified in Recommended Operating Conditions. This rating ensures reliable voltage signature generation across all supported DCP modes-including short-mode (≤200 Ω resistance) and divider modes-while maintaining accuracy over temperature and supply voltage variation. Exceeding ±10 mA may degrade output voltage regulation or cause thermal stress.
