Product details
Overview
TPS25833QWRHBRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive USB Type-C® and BC1.2 charging port controller with integrated synchronous buck DC/DC regulator, delivering 5.1 V ±1% at up to 3.5 A output current over 4.5–36 V input range. It implements cable droop compensation up to 1.5 V, automatic DCP mode detection, and NTC-based thermal warning for infotainment and USB hub applications.
For engineers reviewing the TPS25833QWRHBRQ1 datasheet, TPS25833QWRHBRQ1 pinout, TPS25833QWRHBRQ1 application, or TPS25833QWRHBRQ1 equivalent, key selection criteria include its 32-pin QFN wettable flank package, dual-threshold current limiting (buck + external NFET), thermistor input (NTC), thermal warning flag (THERM_WARN), and compliance with USB Type-C Rev 1.3 and BC1.2 standards.
Technical Context
The TPS25833QWRHBRQ1 integrates a current-mode controlled synchronous buck regulator with internal compensation and adjustable switching frequency (300 kHz–2.2 MHz), supporting frequency synchronization and FPWM with spread-spectrum dithering. Its CC logic handles 3-A/1.5-A current advertisement per USB Type-C, while automatic DCP mode detection enables legacy device compatibility without host intervention.
Unlike the TPS25832-Q1, this variant omits DP/DM analog switches but adds dedicated NTC and THERM_WARN pins for user-programmable thermal overload protection. Integrated protections include cycle-by-cycle current limit, hiccup short-circuit response, VBUS overvoltage lockout, and IEC 61000-4-2 ±8-kV contact / ±15-kV air discharge rating on CC/DP/DM pins.

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 |
|---|---|---|---|
| TPS25832QWRHBRQ1 | Omits NTC input and THERM_WARN; includes DP/DM analog switches for USB 2.0 pass-through. | Suitable for designs requiring USB 2.0 data passthrough (e.g., media hubs with host connectivity), not thermal monitoring. | Select when DP/DM signal routing is required and thermal warning is unnecessary. |
| TPS65988ABHRSMR | USB-C PD 3.0 controller with programmable 5–20 V output, no integrated buck; requires external DC/DC. | Supports variable-output PD contracts and alternate modes (DisplayPort, Thunderbolt); lacks cable compensation and automotive qualification. | Select for full USB PD 3.0 compliance and multi-voltage negotiation, not fixed 5.1 V automotive charging. |
Compared with TPS25833QWRHBRQ1, the TPS25832QWRHBRQ1 trades thermal monitoring for USB 2.0 data pass-through capability, while the TPS65988ABHRSMR offers broader PD protocol support at the cost of added BOM complexity and no AEC-Q100 qualification.

FAQ
What is the primary function of the TPS25833QWRHBRQ1 in an automotive USB-C charging system?
The TPS25833QWRHBRQ1 serves as a complete USB Type-C and BC1.2 charging port controller with integrated synchronous buck regulator. It manages VBUS voltage regulation (5.1 V ±1%), CC logic for plug orientation and current advertisement, automatic DCP mode detection, cable droop compensation up to 1.5 V, and thermal monitoring via NTC input. In automotive systems, it ensures stable, compliant, and robust power delivery to connected devices under varying battery conditions and thermal loads.
How does the TPS25833QWRHBRQ1 implement cable droop compensation, and what design impact does it have?
The TPS25833QWRHBRQ1 implements cable droop compensation by using the IMON pin to set a linear voltage offset applied to the buck regulator's output. With RIMON = 13 kΩ, it delivers up to 1.0 V of compensation; scaling to 1.5 V is achievable with adjusted resistor values. This ensures VBUS measured at the connected device remains constant despite IR drop in long automotive cables, eliminating charge throttling and enabling optimal battery charging performance - a critical requirement for infotainment and rear-seat USB ports.
What thermal protection features does the TPS25833QWRHBRQ1 provide, and how are they configured?
The TPS25833QWRHBRQ1 provides user-programmable thermal protection via the NTC pin (pin 8) and THERM_WARN flag (pin 7). An external NTC thermistor forms a voltage divider whose output is monitored internally. When the voltage exceeds a programmable threshold, the open-drain THERM_WARN pin asserts low. This allows system-level thermal derating (e.g., reducing current limit or disabling port) before reaching die overtemperature shutdown. No configuration registers are needed - behavior is set entirely by analog component selection.
Does the TPS25833QWRHBRQ1 support USB 2.0 data pass-through, and how does it differ from the TPS25832QWRHBRQ1 in this regard?
No, the TPS25833QWRHBRQ1 does not support USB 2.0 data pass-through. Unlike the TPS25832QWRHBRQ1 - which includes DP_OUT and DM_OUT pins for high-bandwidth analog switching of USB 2.0 signals - the TPS25833QWRHBRQ1 replaces those pins with NTC and THERM_WARN for thermal monitoring. This architectural trade-off prioritizes thermal intelligence over data routing, making the TPS25833QWRHBRQ1 ideal for pure power-delivery applications like charging-only ports or modules where thermal safety is paramount.
What are the key differences between the TPS25833QWRHBRQ1 and TPS25832QWRHBRQ1 beyond thermal and data features?
Beyond thermal monitoring (NTC/THERM_WARN) and USB 2.0 pass-through (DP_OUT/DM_OUT), the TPS25833QWRHBRQ1 supports automatic DCP mode detection - enabling compatibility with legacy non-Type-C devices without host software intervention - whereas the TPS25832QWRHBRQ1 requires explicit host control for DCP. Both share identical buck regulator specs (3.5 A, 5.1 V ±1%, 4.5–36 V input), pin-compatible QFN packaging, and AEC-Q100 Grade 1 qualification, ensuring direct PCB reuse where functional requirements align.
