Product details
Overview
TPS25832QCWRHBRQ1 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. It delivers 5.1 V ±1% output at up to 3.5 A, supports 4.5–36 V input, enables cable droop compensation up to 1.5 V, and includes high-bandwidth DP/DM analog switches for USB 2.0 pass-through in infotainment systems.
For engineers reviewing the TPS25832QCWRHBRQ1 datasheet, TPS25832QCWRHBRQ1 pinout, TPS25832QCWRHBRQ1 application, or TPS25832QCWRHBRQ1 equivalent, key selection criteria include its 32-pin QFN wettable flank package, dual-mode current limiting (average or external NFET), USB-IF Rev 1.3 compliance, and integrated CC logic with polarity detection-critical for robust automotive USB power delivery design.
Technical Context
The TPS25832QCWRHBRQ1 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 USB subsystem implements full Type-C CC logic, DCP/SDP mode detection per BC1.2, and automatic cable polarity (POL) signaling.
Unlike the TPS25833-Q1 variant, this device includes DP_OUT and DM_OUT pins for high-bandwidth USB 2.0 data pass-through but omits NTC input and THERM_WARN functionality. Protection features include DP_IN/DM_IN short-to-VBUS, ±8-kV contact/±15-kV air IEC 61000-4-2 ESD rating on CC/DP/DM pins, and cycle-by-cycle current limit.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Input Voltage Range | 4.5 V to 36 V - supports wide automotive battery rail including cold-crank and load-dump conditions. |
| Output Voltage | 5.1 V ±1% - precision regulation ensures stable USB VBUS for compliant charging of portable devices. |
| Max Output Current | 3.5 A - sufficient for dual-port 3-A + 1.5-A USB-C PD sink configurations or high-power single-port applications. |
| Cable Compensation | Up to 1.5 V - linearly adjusts VBUS to counteract voltage drop across long automotive cables, maintaining constant voltage at device end. |
| Switching Frequency | 300 kHz to 2.2 MHz - user-selectable via RT/SYNC pin; enables optimization of efficiency (≤400 kHz) or EMI suppression (>2.1 MHz). |
| USB Data Path | High-bandwidth DP/DM analog switches - preserves USB 2.0 signal integrity with ≤30 mA continuous current handling. |
| ESD Rating | ±8 kV contact / ±15 kV air on CC/DP/DM - meets stringent automotive EMC requirements per IEC 61000-4-2. |
Pinout & Package
TPS25832QCWRHBRQ1 uses a 32-pin VQFN package (RHB0032AA) with 5.00 mm × 5.00 mm body size and wettable flanks for automated optical solder-joint inspection. Thermal pad is electrically connected to PGND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (1,2,3) | Power Input | Primary input supply connection for buck regulator; requires local high-quality bypass capacitors to PGND. |
| SW (28–31) | Switch Node | Connection point between HS/LS FETs; routes to power inductor and bootstrap capacitor (BOOT–SW). |
| CSN/OUT (13) | Buck Output / Current Sense Negative | Regulated 5.1-V VBUS output and negative input of current sense amplifier for cable compensation and current limiting. |
| CSP (14) | Current Sense Positive | Positive input of current sense amplifier; differential voltage vs CSN/OUT sets current limit threshold. |
| DP_OUT (7), DM_OUT (8) | USB 2.0 Data Pass-through Outputs | Drive USB host controller's DP/DM lines; enable full-speed USB 2.0 communication without protocol translation. |
| CC1 (20), CC2 (19) | Type-C Configuration Channel | Analog I/O for detecting plug orientation, sourcing VCONN, and advertising current capability (3-A/1.5-A) per USB-C spec. |
| POL (22) | Cable Polarity Indicator | Active-low open-drain output signaling which CC pin (CC1 or CC2) is connected to the UFP's CC line-enables correct SuperSpeed lane muxing. |
| FAULT (24) | Fault Reporting | Active-low open-drain flag asserted during overcurrent, overvoltage, thermal shutdown, or short-circuit events. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Synchronous Buck Regulator | Eliminates need for external controller + MOSFETs; reduces BOM count and layout area while delivering 3.5-A regulated 5.1-V output. |
| User-Programmable Cable Droop Compensation | Adjusts VBUS linearly with load current using IMON resistor; maintains ≤±1% voltage deviation at device end across full 0–3.5-A range. |
| Dual-Mode Current Limiting | Supports either average-current limiting (via RILIMIT) or external NMOS-based limiting (via LS_GD), enabling fault-tolerant operation where USB port remains powered during overcurrent. |
| USB 2.0 High-Bandwidth Analog Switches | Enables direct DP/DM pass-through with <30 mA continuous current handling-preserves signal integrity without USB protocol stack overhead. |
| AEC-Q100 Grade 1 Qualification | Validated for –40°C to +125°C ambient operation with HBM ±2 kV / CDM ±750 V ESD robustness-meets core automotive reliability requirements. |

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 |
|---|---|---|---|
| TPS25833QCWRHBRQ1 | Omits DP_OUT/DM_OUT; adds NTC input and THERM_WARN pin for thermal monitoring. | Preferred for thermally constrained environments requiring programmable thermal overload protection instead of USB 2.0 data pass-through. | Select TPS25833QCWRHBRQ1 when thermal management via external NTC is prioritized over USB 2.0 data routing. |
| TPS65987DQVQR | USB-C PD 3.0 controller with programmable 5–20-V output, no integrated buck regulator, requires external power stage. | Supports full USB Power Delivery (up to 100 W) and alternate modes (DisplayPort, Thunderbolt); not limited to fixed 5-V output. | Choose TPS65987DQVQR for variable-voltage PD applications requiring >5 V or alternate mode support-requires external DC/DC and more complex firmware. |
Compared with TPS25832QCWRHBRQ1, the TPS25833QCWRHBRQ1 trades DP/DM switches for thermal sensing capability, while TPS65987DQVQR expands functionality to full PD 3.0 but increases system complexity and BOM cost-making TPS25832QCWRHBRQ1 optimal for cost-sensitive, fixed 5-V automotive USB-C charging with data pass-through.

FAQ
What is the primary function of the TPS25832QCWRHBRQ1 in an automotive USB-C system?
The TPS25832QCWRHBRQ1 serves as a complete USB Type-C and BC1.2 charging port controller with integrated synchronous buck regulator. It manages VBUS power delivery (5.1 V ±1% at up to 3.5 A), negotiates USB-C connection and current capability via CC1/CC2, detects cable polarity (POL), and provides high-bandwidth DP/DM analog switches for USB 2.0 data pass-through-all within a single AEC-Q100 Grade 1 qualified IC.
Does the TPS25832QCWRHBRQ1 support USB Power Delivery (PD) beyond USB-C 3-A mode?
No, the TPS25832QCWRHBRQ1 supports USB Type-C Rev 1.3 and BC1.2 charging only-it advertises fixed 3-A or 1.5-A current via CC logic but does not implement USB PD 2.0/3.0 protocol, variable voltage negotiation, or alternate mode support. For full PD functionality, TI recommends the TPS65987DQVQR or similar dedicated PD controllers.
How does cable droop compensation work in the TPS25832QCWRHBRQ1?
Cable droop compensation in the TPS25832QCWRHBRQ1 uses a precision current sense amplifier (CSP–CSN/OUT) to measure output current and dynamically increase VBUS output voltage linearly with load. Configured via the IMON resistor, it offsets voltage drop across automotive cabling-ensuring the connected device sees stable ~5.1 V even at 3.5 A, with compensation up to 1.5 V.
What package type and thermal characteristics apply to the TPS25832QCWRHBRQ1?
The TPS25832QCWRHBRQ1 uses the RHB0032AA 32-pin VQFN package (5.00 mm × 5.00 mm) with wettable flanks. Its thermal metrics include RθJA = 29.4°C/W, RθJB = 9.7°C/W, and RθJC(bot) = 2.3°C/W-optimized for PCB thermal relief via exposed thermal pad connected to PGND, supporting continuous 3.5-A operation in automotive ambient temperatures up to +125°C.
Can the TPS25832QCWRHBRQ1 be used without external current-sense resistors?
No-the TPS25832QCWRHBRQ1 requires external resistors for critical functions: RILIMIT sets the current limit threshold, RIMON configures cable compensation voltage, and RSNS (15 mΩ typical) is mandatory for current sensing in the buck regulator feedback loop. These resistors are essential for accurate current limiting, VBUS regulation, and droop compensation-omitting any invalidates specified performance.
