Product details
Overview
TPS25833QCWRHBRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive USB Type-C® and BC1.2 charging port controller with integrated 36-V input, 5.1-V ±1% synchronous buck regulator delivering up to 3.5 A output current, cable droop compensation up to 1.5 V, and NTC-based thermal warning flag - deployed in infotainment head units for stable 5-V USB power delivery across varying cable lengths and ambient temperatures.
For engineers reviewing the TPS25833QCWRHBRQ1 datasheet, TPS25833QCWRHBRQ1 pinout, TPS25833QCWRHBRQ1 application, or TPS25833QCWRHBRQ1 equivalent, key selection criteria include its automotive-grade thermal warning capability (THERM_WARN), automatic DCP mode support, NTC input (NTC), 32-pin wettable-flank QFN package, and functional safety documentation readiness - all critical for robust in-vehicle USB-C charging design.
Technical Context
The TPS25833QCWRHBRQ1 integrates a current-mode-controlled synchronous buck regulator with internal compensation, adjustable switching frequency (300 kHz–2.2 MHz), and FPWM with spread-spectrum dithering. Its CC logic supports USB Type-C Rev 1.3 and BC1.2 CDP/SDP/DCP modes, including auto-DCP detection unique to the TPS25833-Q1 variant.
It implements cable droop compensation via IMON/ILIMIT resistor programming to linearly adjust VBUS output voltage with load current, maintaining constant voltage at the connected device. Thermal protection uses an NTC input (pin 8) and active-low THERM_WARN flag (pin 7), enabling user-programmable thermal overload response - a feature absent in the TPS25832-Q1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5 V to 36 V - supports wide automotive battery rail variation including cold-crank (4.5 V) and load-dump (36 V) conditions. |
| Output Voltage | 5.1 V ±1% - precision regulation ensures USB-compliant VBUS delivery under dynamic load and temperature. |
| Max Output Current | 3.5 A - sufficient for dual-port 3-A + 1.5-A USB-C PD sink or high-power legacy charging. |
| Cable Compensation | Up to 1.5 V - programmable via IMON resistor to counteract voltage drop across long automotive cables. |
| Switching Frequency | 300 kHz to 2.2 MHz - adjustable via RT/SYNC pin; enables EMI optimization and inductor size trade-offs. |
| Thermal Warning | Dedicated NTC input (pin 8) and THERM_WARN flag (pin 7) - enables system-level thermal derating before junction overtemperature. |
| AEC-Q100 Grade | Grade 1 (–40°C to +125°C TA) - qualified for under-hood and dashboard-mounted automotive applications. |
Pinout & Package
TPS25833QCWRHBRQ1 uses a 32-pin VQFN package (RHB0032AA) with 5.00 mm × 5.00 mm body and wettable flanks for automated optical inspection. Thermal pad is electrically connected to PGND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (pins 1,2,3) | Power input | High-current VIN connection; requires low-ESR bulk capacitance directly to PGND. |
| SW (pins 28–31) | Switch node | Connects to power inductor; high di/dt path requiring tight layout and ground plane stitching. |
| PGND (pins 25–27) | Power ground | Low-impedance return for high-side/low-side FETs and input/output capacitors. |
| NTC (pin 8) | Thermal sensor input | Analog input for NTC thermistor divider; enables PCB temperature monitoring and thermal throttling. |
| THERM_WARN (pin 7) | Thermal alert output | Active-low open-drain flag asserted when NTC voltage exceeds thermal warning threshold. |
| CSN/OUT (pin 13) | Current sense / VBUS output | Regulated 5.1-V output and negative current sense input for buck control loop. |
| CSP (pin 14) | Current sense input | Positive current sense input; differential voltage vs CSN/OUT sets current limit and cable comp gain. |
| RT/SYNC (pin 9) | Frequency control | Resistor-to-ground sets switching frequency; external clock input above PLL threshold enables synchronization. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB-C charging port controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS25832QCWRHBRQ1 | No NTC input or THERM_WARN; includes DP/DM analog switches; no auto-DCP mode. | Suitable for USB 2.0 data passthrough applications (e.g., media hubs), but lacks thermal monitoring for enclosed charging docks. | Select when DP/DM signal routing is required and thermal warning is not needed. |
| TPS65987DQFPRQ1 | USB-C PD controller with 20-V/5-A buck-boost; supports USB PD 3.0, programmable power rules, and dual-role port negotiation. | Required for USB Power Delivery (up to 100 W) and dual-role (source/sink) operation; higher BOM cost and complexity. | Select when USB PD negotiation, variable output voltage, or dual-role capability is mandatory. |
Compared with TPS25832QCWRHBRQ1, the TPS25833QCWRHBRQ1 adds thermal sensing and auto-DCP at the expense of DP/DM switches; compared with TPS65987DQFPRQ1, it offers lower-cost fixed 5-V output with simpler configuration but no PD protocol stack or buck-boost capability.

FAQ
What is the primary function of the TPS25833QCWRHBRQ1 in an automotive USB-C charging system?
The TPS25833QCWRHBRQ1 serves as a complete automotive-grade USB Type-C and BC1.2 charging port controller with an integrated 36-V input synchronous buck regulator. It provides 5.1-V ±1% output at up to 3.5 A, implements cable droop compensation up to 1.5 V, and includes NTC-based thermal monitoring via dedicated NTC and THERM_WARN pins - enabling reliable, thermally aware USB power delivery in head units and charging docks.
Does the TPS25833QCWRHBRQ1 support automatic DCP mode detection?
Yes, the TPS25833QCWRHBRQ1 supports automatic DCP mode detection per USB BC1.2 specification - a feature explicitly confirmed for the TPS25833-Q1 variant in the device comparison table and functional description. This allows seamless charging of legacy non-Type-C devices (e.g., older smartphones) without requiring external mode-selection circuitry or MCU intervention.
How does the cable droop compensation feature work in the TPS25833QCWRHBRQ1?
The TPS25833QCWRHBRQ1 implements cable droop compensation by increasing its regulated VBUS output voltage linearly with load current, using the IMON pin and external resistor to set the compensation slope. When configured for up to 1.5 V compensation, it counteracts voltage drop across automotive cabling so that the measured VBUS at the connected device remains near 5.1 V - ensuring optimal charging efficiency regardless of cable length or gauge.
What package type and thermal characteristics does the TPS25833QCWRHBRQ1 use?
The TPS25833QCWRHBRQ1 uses a 32-pin VQFN package (RHB0032AA) with 5.00 mm × 5.00 mm body and wettable flanks. Its thermal metrics include RθJA = 29.4°C/W and RθJB = 9.7°C/W, with a maximum operating junction temperature of +125°C (Grade 1). The exposed thermal pad must be soldered to a solid PGND plane for effective heat dissipation in high-current automotive applications.
Is the TPS25833QCWRHBRQ1 compatible with USB Type-C Rev 1.3 and BC1.2 standards?
Yes, the TPS25833QCWRHBRQ1 is explicitly compliant with USB Type-C Rev 1.3 and USB Battery Charging (BC1.2) Rev 1.2 standards. It implements full CC logic for 3-A/1.5-A current advertisement, VCONN sourcing and discharge, cable polarity detection (POL), and CDP/SDP/DCP mode support - all verified in the official TI datasheet Features and Description sections.
