Texas Instruments TPS2514ADBVT

Overview

TPS2514ADBVT from Texas Instruments is a single-port USB Dedicated Charging Port (DCP) controller that implements BC1.2, YD/T 1591-2009, Divider 1 (2.7 V/2.0 V), and 1.2 V/1.2 V charging signatures on D+ and D– lines. It operates from 4.5 V to 5.5 V, delivers ±10 mA data-line drive capability, and integrates undervoltage lockout with 4.1 V turn-on threshold. It enables fast-charging compliance in compact AC-DC adapters and vehicle USB chargers.

For engineers reviewing the TPS2514ADBVT datasheet, TPS2514ADBVT pinout, TPS2514ADBVT application, or TPS2514ADBVT equivalent, key selection criteria include supported DCP modes (BC1.2 short, Divider 1, 1.2 V/1.2 V), SOT-23-6 package constraints, auto-detect behavior between signature schemes, and compatibility with 5-W and 10-W USB charger topologies requiring precise D+/D– voltage control.

Technical Context

The TPS2514ADBVT implements an analog auto-detect circuit that monitors D+ and D– line voltages to select among three DCP signature modes: BC1.2/YD/T short mode (≤200 Ω resistance), Divider 1 (2.7 V on DP1, 2.0 V on DM1), and 1.2 V/1.2 V mode (1.2 V on both DP1 and DM1). It does not support Divider 2 or Divider 3 modes - those are exclusive to TPS2513/TPS2513A dual-port variants.

Its functional block includes UVLO with 100 mV hysteresis, internal current-limited drivers for DP1 and DM1, and no-connect (N/C) pins 3 and 4. Unlike dual-port TPS2513x, it lacks DP2/DM2 terminals and associated detection logic, confirming its role as a dedicated single-port solution for space-constrained USB power delivery systems.

Compared with TPS2513ADBVT, TPS2514ADBVT reduces system cost and board area by eliminating redundant DP2/DM2 circuitry and associated routing. Against TPS2514ADBVTE4, it trades extended temperature rating and MSL 1 qualification for lower unit price and standard industrial temperature grade - ideal for cost-sensitive, thermally benign USB charger designs.

FAQ

What USB charging standards does the TPS2514ADBVT support?

The TPS2514ADBVT supports USB Battery Charging Specification 1.2 (BC1.2) short-mode DCP, Chinese Telecommunications Standard YD/T 1591-2009 short-mode, Divider 1 DCP (2.7 V on D+, 2.0 V on D–), and 1.2 V/1.2 V DCP mode. It does not support Divider 2, Divider 3, or CDP modes. All supported signatures are implemented in hardware with no firmware required, and TPS2514ADBVT automatically selects the correct mode based on detected device behavior.

How does the TPS2514ADBVT differ from the TPS2513ADBVT?

The TPS2514ADBVT is a single-port DCP controller with DP1 and DM1 pins only, while the TPS2513ADBVT is a dual-port device with DP1/DM1 and DP2/DM2. TPS2514ADBVT supports Divider 1 (2.7 V/2.0 V) and 1.2 V/1.2 V modes but excludes Divider 2 and Divider 3. TPS2513ADBVT supports all three divider modes plus dual-port operation. Pin 3 and pin 4 on TPS2514ADBVT are N/C, whereas TPS2513ADBVT uses them for DP2 and DM2 - making them non-pin-compatible.

What is the purpose of the N/C pins on the TPS2514ADBVT?

Pins 3 and 4 on the TPS2514ADBVT are no-connect (N/C) terminals - they are internally unconnected and serve no electrical function. They may be left floating or tied to GND without affecting operation. This simplifies PCB layout versus dual-port variants and confirms TPS2514ADBVT's single-channel architecture. Neither pin carries current, timing signals, or configuration functions - their presence maintains SOT-23-6 mechanical compatibility across the TPS251xx family.

Does the TPS2514ADBVT require external resistors or configuration components?

No, the TPS2514ADBVT requires only a 0.1 µF ceramic bypass capacitor from IN to GND placed adjacent to the device. It contains all necessary biasing, detection, and driver circuitry internally - no external resistors, MOSFETs, or pull-up/down networks are needed to implement any supported DCP signature. This eliminates calibration drift, reduces BOM count, and ensures consistent signature accuracy across temperature and voltage ranges - a key advantage over discrete DCP solutions.

Can the TPS2514ADBVT be used in a USB-C PD design?

Yes, the TPS2514ADBVT can serve as a companion DCP controller in USB-C PD systems - for example, driving the D+/D– lines of a legacy USB-A port while a separate USB-C PD controller (e.g., TPS65987) manages the USB-C port. It does not replace or interface with PD communication; instead, it provides backward-compatible charging for non-PD devices. Its low quiescent current and small SOT-23-6 footprint make it ideal for multi-port PD adapters needing mixed legacy/PD support.
