Texas Instruments TPS2513ADBVR

Overview

TPS2513ADBVR from Texas Instruments is a dual-port USB Dedicated Charging Port (DCP) controller that implements BC1.2, YD/T 1591-2009, Divider 1 (2.0 V/2.7 V), Divider 2 (2.7 V/2.0 V), and 1.2 V/1.2 V charging signature protocols. It operates from 4.5 V to 5.5 V, delivers ±10 mA data-line drive capability, and supports automatic D+/D− line switching for compliant smartphone and tablet fast-charging in vehicle and AC-DC adapter applications.

For engineers reviewing the TPS2513ADBVR datasheet, TPS2513ADBVR pinout, TPS2513ADBVR application, or TPS2513ADBVR equivalent, key selection considerations include dual-port DCP auto-detection logic, SOT-23-6 package compatibility, 200 Ω max short-mode resistance, 24–36 kΩ output impedance in divider mode, and support for 5-W and 10-W USB charger topologies without external microcontroller intervention.

Technical Context

The TPS2513ADBVR integrates two independent DCP detection and signature generation channels (DP1/DM1 and DP2/DM2), each with auto-detect circuitry that monitors D+ and D− line voltages to select among six charging schemes. Its internal UVLO (4.1 V threshold, 100 mV hysteresis) ensures stable operation only within the 4.5–5.5 V input range, while thermal metrics (RθJA = 179.9 °C/W) confirm suitability for compact, unheatsinked designs.

Unlike single-port variants (e.g., TPS2514), the TPS2513ADBVR enables simultaneous control of two USB ports using shared power supply and separate data-line routing - critical for dual-socket automotive chargers and multi-port wall adapters. Its pin-compatible family includes TPS2513A (supports only Divider 3: 2.7 V/2.7 V) but excludes N/C pins found in TPS2514x variants.

FAQ

What charging protocols does the TPS2513ADBVR support?

The TPS2513ADBVR supports USB Battery Charging Specification 1.2 (BC1.2) short mode, Chinese Telecommunications Standard YD/T 1591-2009, Divider 1 (2.0 V on D+, 2.7 V on D−), Divider 2 (2.7 V on D+, 2.0 V on D−), and 1.2 V on both D+ and D− lines. It does not support USB PD, CDP, or SDP enumeration - TPS2513ADBVR is strictly a DCP controller.

How does the TPS2513ADBVR handle dual-port operation?

The TPS2513ADBVR contains two independent DCP controller channels: DP1/DM1 for Port 1 and DP2/DM2 for Port 2. Each channel performs autonomous auto-detection and applies the appropriate signature without cross-interference. Pin 3 (DP2) and Pin 4 (DM2) enable true concurrent operation - unlike single-port alternatives such as TPS2514ADBVR.

What is the purpose of the IN pin on the TPS2513ADBVR?

The IN pin (Pin 5) supplies power to the TPS2513ADBVR and must be connected to a stable 4.5–5.5 V source. A minimum 0.1 µF ceramic capacitor must be placed between IN and GND, located as close as possible to the device, to ensure proper UVLO function and stable operation during load transients - failure to do so may cause erratic signature generation or lockup.

Can the TPS2513ADBVR be used in place of the TPS2513A or TPS2514 variants?

No - the TPS2513ADBVR supports Divider 1 and Divider 2 modes (2.0 V/2.7 V and 2.7 V/2.0 V), whereas TPS2513A only supports Divider 3 (2.7 V/2.7 V). TPS2514 variants are single-port and have N/C pins instead of DP2/DM2. Substituting them would require PCB redesign and firmware changes due to incompatible pin functions and protocol coverage.

What is the maximum continuous current the TPS2513ADBVR can deliver to a connected device?

The TPS2513ADBVR itself does not deliver power - it only controls D+/D− signaling. The actual charging current (up to 1.5 A per port) is delivered via the VBUS line from an external power stage (e.g., buck converter or LDO). TPS2513ADBVR's role is strictly to negotiate that current limit via compliant electrical signatures on the data lines.
