TPS2514AQDBVRQ1 Overview
What is a USB Dedicated Charging Port controller? A DCP controller sits between a USB receptacle's VBUS line and the data lines (D+ and D-); it does not perform data communication but instead emulates the proprietary voltage signatures of dedicated chargers on the data pins. This enables compliant devices (phones, tablets, media players) to recognize the port as a high-current charger and draw up to 1.5 A (BC1.2) or 2.4 A (Apple mode) without enumeration. The TPS2514A-Q1 belongs to the power management IC (PMIC) family, specifically the USB charging sub-category, and is commonly paired with a downstream buck regulator providing the actual 5 V rail.
Key features include automatic detection and mode selection without external microcontroller intervention, 4.5 V to 5.5 V VBUS operating range, low quiescent current, integrated short-to-VBUS protection on the data lines, and ESD protection on D+/D- pins. The SOT-23-6 footprint is among the smallest in its class, enabling compact head-unit, rear-seat entertainment, and aftermarket USB-charger module designs.
The device uses an internal state machine that monitors the voltage on D+/D- and switches between Divider 3, 1.2 V, and BC1.2 modes based on what the attached device expects. Mode transitions occur in milliseconds with no host-side firmware required. Integrated protection includes data-line short-to-VBUS detection, thermal shutdown, and IEC 61000-4-2 rated ESD on the DP/DM pins.
Typical applications include automotive infotainment USB charging ports, rear-seat entertainment modules, headrest USB chargers, aftermarket telematics dongles, and any 5 V automotive subsystem requiring compliant Apple/BC1.2 charging signatures. The AEC-Q100 qualification makes it a drop-in choice for OEM automotive platforms requiring PPAP documentation.
When designing with this part, place 0.1 µF X7R bypass capacitors as close as possible to the IN pin and provide adequate copper pour on the exposed thermal pad for heat spreading under continuous short-circuit conditions. Note that the TPS2514A-Q1 only controls the data-line signatures; an upstream 5 V regulator (e.g., TPS62150 or LMR14030) is still required to source VBUS current.

Typical Applications
TPS2514AQDBVRQ1 is suitable for 6 applications: Automotive Infotainment USB Charging Port, Rear-Seat Entertainment USB Module, Aftermarket Telematics Dongle / OBD-II Charger, Wall-Mounted Automotive USB Charger Adapter, Industrial HMI with USB Charging Port, Docking Station with USB Charging Output.
Automotive Infotainment USB Charging Port
The TPS2514AQDBVRQ1 is purpose-built for the USB charging ports in automotive head units where phones and tablets must negotiate 1.5 A (BC1.2) or 2.4 A (Apple mode) without enumeration. Its AEC-Q100 Grade 1 qualification over -40°C to +125°C meets OEM cabin-temperature requirements. The integrated auto-detect state machine applies BC1.2 shorted-mode, YD/T 1591-2009, or Apple 2.7 V/2.0 V divider signatures on D+/D- based on the attached device, allowing phones to draw full charging current without software intervention. The SOT-23-6 footprint fits alongside the main USB hub IC on a compact infotainment PCB.

Rear-Seat Entertainment USB Module
Rear-seat entertainment (RSE) modules and headrest-mounted displays rely on compact, automotive-grade charging interfaces for passenger devices. The TPS2514AQDBVRQ1's 2.90 mm x 1.60 mm SOT-23-6 footprint and minimal external BOM make it ideal for space-constrained RSE enclosures. It automatically negotiates the highest compatible charging mode (BC1.2 / YD/T 1591-2009 / Apple) for any plugged-in device, eliminating the need for an MCU-driven solution. IEC 61000-4-2 ESD protection on the data pins survives the electrostatic discharge events common in dry cabin environments.
Recommended
Aftermarket Telematics Dongle / OBD-II Charger
Aftermarket telematics dongles and OBD-II port accessories increasingly include USB charging outlets for fleet tablets. The TPS2514AQDBVRQ1 allows these products to advertise BC1.2 and Apple charging signatures to attached devices. Because no microcontroller or firmware is required, designers can add a fully compliant USB charging port using only this SOT-23-6 device plus a 5 V buck regulator. The AEC-Q100 qualification and -40°C cold-start tolerance suit under-dash installations where temperatures can drop sharply overnight.
Recommended
Wall-Mounted Automotive USB Charger Adapter
Aftermarket 12V-to-USB charging adapters sold for cars and trucks must reliably charge both Android (BC1.2) and Apple (divider-mode) devices. The TPS2514AQDBVRQ1's automatic mode selection covers both ecosystems with a single IC. Its integrated short-to-VBUS protection on D+/D- prevents damage if the data pins are accidentally shorted to the VBUS pin during harness assembly. The Q1 automotive qualification allows the same BOM to be marketed for OEM and aftermarket automotive segments.
Recommended
Industrial HMI with USB Charging Port
Industrial human-machine interface (HMI) panels and factory-floor terminals increasingly include USB ports for charging operator tablets or barcode scanners. The TPS2514AQDBVRQ1's wide 4.5 V to 5.5 V operating range and -40°C to +125°C thermal tolerance suit cabinet-mounted equipment subject to temperature swings. It enables the HMI to provide BC1.2-compliant charging without modifying host firmware. The SOT-23-6 package is small enough to fit alongside USB type-C connectors on densely populated interface boards.
Recommended
Docking Station with USB Charging Output
Laptop docking stations and conference-room A/V hubs often expose USB-A ports intended for charging rather than data. The TPS2514AQDBVRQ1 turns each port into a compliant BC1.2 / Apple charging source, enabling faster charging of conference-room devices without host enumeration. Its small SOT-23-6 footprint allows multiple ports to share a single PCB without congestion. The integrated short-to-VBUS detection on D+/D- protects the host if a faulty cable shorts the data lines.

Design Notes
Estimated: The TPS2514AQDBVRQ1 itself draws only a few hundred microamps from IN, but the design must include a 5 V upstream regulator (e.g., TPS62150 or LMR14030) capable of sourcing 1.5 A (BC1.2) or 2.4 A (Apple mode). Add a 22 µF bulk capacitor on IN to absorb load transients when a device switches from suspend to full charging current. Place a 0.1 µF X7R bypass within 2 mm of the IN pin.
Do not route DP/DM traces near switching-node or motor-drive signals - the auto-detect state machine relies on clean D+/D- voltage levels. Use 90 Ω differential impedance for the DP/DM pair and keep total length under 50 mm to minimize reflection-induced false mode selection. Always populate C_BYPASS on IN; missing bypass causes erratic mode switching.
Place the TPS2514AQDBVRQ1 as close as possible to the USB receptacle pins to minimize parasitic inductance on DP/DM. The SOT-23-6 thermal pad (DBV) does not have an exposed pad but shares a small GND lead; ensure the GND pin has a direct via to the ground plane. For automotive ESD compliance, consider adding a TPD2E001 or TPD4E05U06 external ESD array on the connector side of the DP/DM lines.
