Texas Instruments TPS2514ADBVR

Overview

TPS2514ADBVR from Texas Instruments is a single-port USB Dedicated Charging Port (DCP) controller that identifies and signals compliant portable devices via D+ and D– line voltage signatures. It supports BC1.2 short-mode, YD/T 1591-2009 short-mode, 1.2 V/1.2 V mode, and Divider 1 (2.0 V/2.7 V) and Divider 2 (2.7 V/2.0 V) modes - all within 4.5 V to 5.5 V supply range and in SOT-23-6 package. It enables fast-charging handsets and tablets in wall adapters and vehicle chargers.

For engineers reviewing the TPS2514ADBVR datasheet, TPS2514ADBVR pinout, TPS2514ADBVR application, or TPS2514ADBVR equivalent, key selection criteria include supported charging protocols (BC1.2, YD/T 1591, Divider 1/2, 1.2 V), auto-detect behavior on DP1/DM1 lines, UVLO threshold (4.1 V typ), low quiescent current (200 µA max), and SOT-23-6 thermal performance (R_θJA = 179.9 °C/W).

Technical Context

The TPS2514ADBVR implements an auto-detect state machine that monitors D+ and D– line voltages to determine attached device type and applies corresponding signature voltages on DP1 and DM1 pins. It supports five DCP detection schemes without external components: shorted D+/D– (≤200 Ω), 2.0 V/2.7 V divider, 2.7 V/2.0 V divider, 1.2 V/1.2 V bias, and BC1.2/YD/T 1591 compliance.

Its internal UVLO circuit disables output drivers until IN reaches 4.1 V (typ), with 100 mV hysteresis to prevent oscillation during input transients. All outputs (DP1, DM1) feature ±10 mA continuous sink/source capability and 24–36 kΩ output impedance in divider mode, enabling robust interface with legacy and modern USB charging ICs.

FAQ

What charging protocols does the TPS2514ADBVR support?

The TPS2514ADBVR supports five USB Dedicated Charging Port protocols: BC1.2 short-mode (D+/D– ≤200 Ω), Chinese YD/T 1591-2009 short-mode, 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/1.2 V bias mode. It automatically detects and applies the correct signature without external configuration - all implemented in the TPS2514ADBVR silicon.

Does the TPS2514ADBVR require external resistors or firmware to operate?

No. The TPS2514ADBVR operates autonomously using internal auto-detect circuitry and precision voltage references. It needs only a 0.1 µF ceramic capacitor from IN to GND and direct connection of DP1/DM1 to USB D+/D– lines. No external resistors, microcontroller, or firmware is required - the TPS2514ADBVR handles all protocol selection and voltage generation internally.

How does the TPS2514ADBVR handle undervoltage conditions?

The TPS2514ADBVR incorporates an undervoltage lockout (UVLO) circuit that disables DP1 and DM1 outputs until the IN supply reaches 4.1 V (typ), with 100 mV hysteresis. This prevents erratic signaling during power-up or brown-out events. Once enabled, the TPS2514ADBVR maintains stable DCP signatures across its full 4.5 V to 5.5 V operating range.

Can the TPS2514ADBVR be used in a dual-port charger design?

The TPS2514ADBVR is a single-port controller and does not support dual USB ports. For dual-port applications, TI recommends the pin-compatible TPS2513ADBVR (dual-port version) which integrates two independent DCP controllers in one SOT-23-6 package - each with identical TPS2514ADBVR functionality on separate DP/DM pairs.

What is the thermal performance of the TPS2514ADBVR in SOT-23-6 package?

The TPS2514ADBVR in DBV (SOT-23-6) package has a junction-to-ambient thermal resistance (R_θJA) of 179.9 °C/W. With its 200 µA max supply current and no internal power switching, self-heating is negligible - allowing reliable operation up to +125 °C junction temperature even in sealed enclosures, provided the PCB includes adequate GND copper area per TI layout guidelines.
