Product details
Overview
TPS25810ATWRVCRQ1 from Texas Instruments is an AEC-Q100 Grade T automotive-qualified USB Type-C downstream-facing port (DFP) controller with integrated 3.4-A power switch, 34-mΩ rDS(on), digital cable compensation, and VCONN support for electronically marked cables. It operates from 4.5–6.5 V on IN1, detects UFP/auxiliary attachments via CC1/CC2, and delivers stable 5-V bus power in automotive infotainment and rear-seat charging systems.
For engineers reviewing the TPS25810ATWRVCRQ1 datasheet, TPS25810ATWRVCRQ1 pinout, TPS25810ATWRVCRQ1 application, or TPS25810ATWRVCRQ1 equivalent, key selection criteria include its automotive-grade thermal shutdown (155°C), 0.7-µA quiescent current in unattached state, fixed 3.4-A current limit with ±7.1% tolerance, and open-drain status outputs (UFP, AUDIO, DEBUG, FAULT) for system-level USB accessory identification and fault reporting.
Technical Context
The TPS25810ATWRVCRQ1 implements a dual-path power architecture: a 34-mΩ high-side VBUS switch (IN1→OUT) with 3.4-A current limiting and a separate 365-mΩ VCONN switch (IN2→CC1/CC2) rated for 355-mA short-circuit current. It uses analog CC line monitoring to resolve cable orientation (via POL output), identify UFPs (Rd termination), powered cables (Ra), audio (Ra/Ra), and debug accessories (Rd/Rd), all without USB PD negotiation.
Its digital cable compensation (CS output active above 1.95-A load) offsets voltage droop by enabling external circuitry to adjust source voltage, while power-wake capability allows operation from 2.9–5.5-V AUX supply during S4/S5 low-power states-enabling system-level hibernation without disconnecting the Type-C port.

FAQ
What is the primary function of the TPS25810ATWRVCRQ1 in a USB Type-C system?
The TPS25810ATWRVCRQ1 serves as a dedicated downstream-facing port (DFP) controller with integrated power switches for VBUS and VCONN. It handles USB Type-C attachment detection, current advertisement (STD/1.5-A/3-A), cable orientation resolution (via POL), and accessory identification (audio/debug) - all without requiring USB Power Delivery negotiation. Its core role is enabling compliant, robust 5-V USB-C connectivity in automotive environments.
Does the TPS25810ATWRVCRQ1 support USB Power Delivery (PD) protocol negotiation?
No, the TPS25810ATWRVCRQ1 does not support USB Power Delivery (PD) protocol negotiation. It is designed strictly for USB Type-C Rev. 1.2 DFP operation with fixed 5-V VBUS delivery. It advertises current capability (up to 3 A) via CC-line resistive signaling but lacks the BMC transceiver, PD controller, or firmware required for PD contract establishment. For PD-enabled systems, TI recommends the TPS65987D-Q1 instead.
How does the digital cable compensation feature work in the TPS25810ATWRVCRQ1?
The TPS25810ATWRVCRQ1 monitors load current via internal sensing and asserts the open-drain CS output when current exceeds 1.95 A (rising threshold). This signal enables external circuitry - such as a DAC-controlled adjustable regulator - to raise the VBUS source voltage and compensate for IR drop across cables and connectors. The 125-mA hysteresis prevents chatter near the threshold, ensuring stable regulation under dynamic loads.
What are the thermal management requirements for the TPS25810ATWRVCRQ1?
The TPS25810ATWRVCRQ1 requires connection of its exposed thermal pad to the PCB ground plane to achieve the specified RθJB of 13°C/W. Without proper thermal pad soldering, junction temperature rise may exceed limits during sustained 3.4-A operation. The device features dual thermal thresholds: 135°C initiates VBUS/VCONN current-limit derating, and 155°C triggers full shutdown - both validated per AEC-Q100 Grade T requirements.
Can the TPS25810ATWRVCRQ1 operate from a single 5-V supply, or are multiple rails required?
The TPS25810ATWRVCRQ1 supports flexible supply configurations: IN1 (4.5–6.5 V) powers the VBUS switch, IN2 (4.5–5.5 V) powers VCONN, and AUX (2.9–5.5 V) supplies the logic core. All three can be tied together if only one rail is available. However, separating IN1/IN2 enables independent control (e.g., disabling VCONN when no marked cable is attached), and using a lower-voltage AUX rail (e.g., 3.3 V) enables ultra-low-quiescent operation during system hibernate.
