Texas Instruments TPS2513AQDBVRQ1

Overview

TPS2513AQDBVRQ1 from Texas Instruments is a dual-channel automotive-grade USB Dedicated Charging Port (DCP) controller that implements BC1.2-compliant auto-detection and electrical signature generation on two independent USB data paths (DP1/DM1 and DP2/DM2). It operates from 4.5 V to 5.5 V, delivers 2.7 V or 1.2 V D+/D− output voltages with ≤36 kΩ output impedance in Divider Mode, supports shorted-mode resistance ≤200 Ω, and is qualified per AEC-Q100 Grade 1 (–40°C to +125°C). It enables fast charging of smartphones and tablets in vehicle-mounted USB power adapters.

For engineers reviewing the TPS2513AQDBVRQ1 datasheet, TPS2513AQDBVRQ1 pinout, TPS2513AQDBVRQ1 application, or TPS2513AQDBVRQ1 equivalent, key selection criteria include dual-port BC1.2 DCP compliance, SOT-23-6 automotive packaging, UVLO threshold at 4.1 V ±0.2 V, ≤220 µA supply current, and support for Divider 3 (2.7 V/2.7 V), Shorted (D+/D− <200 Ω), and 1.2 V/1.2 V charging modes without external components.

Technical Context

The TPS2513AQDBVRQ1 integrates two independent DCP detection and signature generation channels-each with auto-detect logic that monitors D+ and D− line voltage transitions to select between Divider 3 (2.7 V/2.7 V), BC1.2 Shorted (D+/D− shorted ≤200 Ω), and 1.2 V/1.2 V modes. Its internal UVLO circuit disables all outputs until IN reaches 4.1 V, with 100 mV hysteresis to prevent oscillation during input droop.

Each channel features dedicated I/O pins (DP1/DM1 and DP2/DM2) with bidirectional capability, supporting sink/source currents up to ±10 mA, and output impedances tightly controlled at 24–36 kΩ (Divider Mode) or 80–130 kΩ (1.2 V Mode). The device requires only a single 0.1 µF ceramic capacitor on the IN pin and no external resistors or timing components.

FAQ

What USB charging protocols does the TPS2513AQDBVRQ1 support?

The TPS2513AQDBVRQ1 supports USB Battery Charging Specification Revision 1.2 (BC1.2) Dedicated Charging Port modes-including Divider 3 (2.7 V/2.7 V), Shorted Mode (D+/D− ≤200 Ω), and 1.2 V/1.2 V Mode-as well as the Chinese Telecommunications Industry Standard YD/T 1591-2009. It does not support USB Power Delivery (PD) or Qualcomm Quick Charge protocols. Each of its two channels operates independently, enabling full protocol compliance on both USB ports simultaneously.

Can the TPS2513AQDBVRQ1 be used without an external USB power switch?

Yes, the TPS2513AQDBVRQ1 can be used without an external USB power switch because it only controls D+/D− signaling and does not regulate VBUS power. However, overcurrent protection must be implemented separately-TI recommends pairing it with the TPS2561A-Q1 for dual-port automotive applications. The TPS2513AQDBVRQ1 itself draws only 220 µA and has no current-handling capability on VBUS.

What is the function of the IN pin on the TPS2513AQDBVRQ1?

The IN pin on the TPS2513AQDBVRQ1 is the sole power supply input, accepting 4.5 V to 5.5 V. It powers all internal circuitry including both DCP channels and the UVLO comparator. A minimum 0.1 µF ceramic capacitor must be placed between IN and GND, located as close as possible to the pin, to ensure stable operation and suppress high-frequency noise from the VBUS rail.

How does the auto-detect feature of the TPS2513AQDBVRQ1 determine which charging mode to activate?

The TPS2513AQDBVRQ1 auto-detect feature monitors voltage transitions on DP1/DM1 and DP2/DM2 using internal comparators. When a device connects, it first checks for Divider 3 signature (2.7 V on both lines); if absent, it detects shorted-mode behavior (D+/D− voltage convergence below 0.8 V); if neither is confirmed, it defaults to 1.2 V/1.2 V mode. No external components or configuration are needed-the decision is fully autonomous and occurs within milliseconds of attachment.

Is the TPS2513AQDBVRQ1 pin-compatible with the TPS2514AQDBVRQ1?

No, the TPS2513AQDBVRQ1 is not pin-compatible with the TPS2514AQDBVRQ1. While both use the SOT-23-6 (DBV) package, their pinouts differ: TPS2513AQDBVRQ1 uses pins 3 (DP2) and 4 (DM2) for its second channel, whereas TPS2514AQDBVRQ1 leaves those pins as N/C. Swapping them would disconnect the second channel or cause undefined behavior. Board layout must match the specific device's pin configuration.
