Product details
Overview
TPS25832QWRHBRQ1 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 features cable droop compensation up to 1.5 V, high-bandwidth DP/DM analog switches, and CC logic for 3-A/1.5-A current advertisement-designed for USB media hubs and infotainment systems requiring stable VBUS under variable load.
For engineers reviewing the TPS25832QWRHBRQ1 datasheet, TPS25832QWRHBRQ1 pinout, TPS25832QWRHBRQ1 application, or TPS25832QWRHBRQ1 equivalent, key selection criteria include its 32-pin QFN wettable flank package, 300 kHz–2.2 MHz adjustable switching frequency, FPWM with spread-spectrum dithering, internal compensation, and USB-IF Rev 1.3 compliance-critical for automotive USB power delivery integrity and ESD robustness (±8-kV contact, ±15-kV air).
Technical Context
The TPS25832QWRHBRQ1 implements a current-mode controlled synchronous buck regulator with internal compensation and programmable frequency via RT/SYNC pin. Its dual-path current sensing supports both average current limit (via CSP–CSN/OUT voltage threshold) and external NMOS-based overcurrent protection using LS_GD gate drive.
It integrates full USB Type-C port controller functionality-including CC1/CC2 logic for Rp/Rd detection, POL output for cable orientation, LD_DET for UFP identification, and DP_IN/DP_OUT & DM_IN/DM_OUT pass-through switches-while omitting NTC input and thermal warning flag (features exclusive to TPS25833-Q1).
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 transients. |
| Output Voltage | 5.1 V ±1% - tightly regulated VBUS ensures optimal charging for connected USB devices regardless of cable length. |
| Max Output Current | 3.5 A - enables full-power USB-C PD sink capability without external current boosting. |
| Cable Compensation | Up to 1.5 V linear droop correction - maintains constant VBUS at device end by increasing output voltage proportionally with load current. |
| Switching Frequency | 300 kHz to 2.2 MHz - adjustable via RT resistor or external clock sync; avoids AM band above 2.1 MHz. |
| ESD Rating | ±8-kV contact / ±15-kV air (IEC 61000-4-2 on DP/DM/CC pins) - meets automotive EMC requirements without external TVS. |
| AEC-Q100 Grade | Grade 1 (–40°C to +125°C TA) - qualified for under-hood and dashboard-mounted infotainment applications. |
Pinout & Package
TPS25832QWRHBRQ1 uses a 32-pin VQFN package (RHB0032AA), 5.00 mm × 5.00 mm body size, with wettable flanks for automated optical solder inspection. Thermal pad is electrically connected to PGND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (1,2,3) | Power Input | High-current VIN connection to automotive supply; requires low-ESR bulk capacitance directly to PGND. |
| SW (28–31) | Power Switch Node | Connection point for external inductor; ties internal HS/LS FETs; demands short, low-inductance routing. |
| PGND (25–27) | Power Ground | High-current return path for buck converter; must be solidly tied to thermal pad and AGND at single point. |
| AGND (16) | Analog Ground | Reference for internal references, CC logic, and current sense amplifier; isolated from noisy PGND except at star point. |
| DP_IN / DM_IN (17,18) | USB Data Input | Connects to Type-C receptacle DP/DM lines; includes short-to-VBUS protection and IEC-rated ESD clamps. |
| DP_OUT / DM_OUT (7,8) | USB Data Output | Drives host-side DP/DM lines; high-bandwidth analog switches enable full-speed USB 2.0 pass-through (TPS25832-Q1 only). |
| CC1 / CC2 (19,20) | Configuration Channel | Dual analog I/O for USB-C plug detection, Rp/Rd termination, VCONN sourcing, and polarity identification (POL). |
| CSN/OUT (13) | Current Sense Negative / Buck Output | Feedback node for current limit and output regulation; also serves as VBUS output when used in buck mode. |
| CSP (14) | Current Sense Positive | Sense input across external shunt; difference with CSN/OUT sets current limit threshold and cable comp gain. |
| RT/SYNC (9) | Frequency Control | Resistor-to-ground sets switching frequency; pulled above PLL threshold becomes external clock input for synchronization. |
| FAULT (24) | Fault Indicator | Active-low open-drain flag signaling overvoltage, overcurrent, thermal shutdown, or CC fault conditions. |
| EN/UVLO (4) | Enable & UVLO Input | Logic-level enable with precision 1.14 V rising threshold; supports adjustable UVLO via external resistor divider. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated Synchronous Buck Regulator | Eliminates need for external controller + MOSFETs; delivers 3.5 A at 5.1 V with internal compensation and FPWM operation. |
| USB Type-C & BC1.2 Dual Compliance | Supports 3-A/1.5-A current advertisement per USB-C Rev 1.3 and legacy CDP/SDP signatures per BC1.2 Rev 1.2. |
| Programmable Cable Droop Compensation | Linear VBUS boost up to 1.5 V compensates for voltage drop across long automotive cables, preserving charging efficiency. |
| High-Bandwidth DP/DM Analog Switches | Enables full-speed USB 2.0 data pass-through between connector and host controller without signal degradation. |
| Robust Integrated Protection | Includes cycle-by-cycle current limit, hiccup short-circuit, VBUS OVP/UVP, CC overvoltage, DP/DM short-to-VBUS, and die overtemperature. |

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 |
|---|---|---|---|
| TPS25833QWRHBRQ1 | Includes NTC input and THERM_WARN flag; adds DCP auto-mode; lacks DP/DM switches. | Preferred for thermally constrained designs needing user-programmable thermal overload protection; not suitable where USB 2.0 data pass-through is required. | Select TPS25833QWRHBRQ1 when thermal monitoring is critical and DP/DM switching is unnecessary. |
| TPS65987DQWRJURQ1 | USB-C PD controller with 20-V/5-A buck-boost, supports USB PD 3.0, no integrated BC1.2 logic or cable compensation. | Targets higher-power PD applications (e.g., laptop charging); requires external BC1.2 circuitry and lacks automotive-optimized cable droop correction. | Choose TPS65987DQWRJURQ1 only when USB PD 3.0 negotiation and >5-V output are mandatory. |
Compared with TPS25832QWRHBRQ1, TPS25833QWRHBRQ1 trades DP/DM switching for thermal sensing capability, while TPS65987DQWRJURQ1 provides full USB PD 3.0 but omits BC1.2 integration and cable compensation-making TPS25832QWRHBRQ1 the optimal choice for cost-sensitive, 5-V-only automotive USB-C charging with data passthrough.

FAQ
What is the maximum supported USB data rate for TPS25832QWRHBRQ1?
The TPS25832QWRHBRQ1 supports full-speed USB 2.0 data rates up to 480 Mbps through its integrated high-bandwidth DP/DM analog switches. These switches maintain signal integrity across the entire USB 2.0 bandwidth and are explicitly validated for use in automotive environments with stringent EMI requirements.
Does TPS25832QWRHBRQ1 support USB Power Delivery (PD) protocol negotiation?
No, the TPS25832QWRHBRQ1 does not support USB PD protocol negotiation. It implements USB Type-C Rev 1.3 port controller functionality for fixed 5-V output with 1.5-A or 3-A current advertisement via CC logic, and complies with BC1.2 for legacy device detection-but lacks BMC communication hardware required for USB PD 2.0/3.0.
How is cable droop compensation implemented in TPS25832QWRHBRQ1?
TPS25832QWRHBRQ1 implements linear cable droop compensation by increasing its buck output voltage (CSN/OUT) proportionally to load current, based on the voltage difference between CSP and CSN/OUT. With RIMON = 13 kΩ, it delivers up to 1.5 V of compensation-ensuring constant VBUS at the connected device regardless of cable resistance.
Can TPS25832QWRHBRQ1 operate with input voltage below 4.5 V?
No, the absolute minimum operating input voltage for TPS25832QWRHBRQ1 is 4.5 V as specified in Recommended Operating Conditions. Operation below this level may cause UVLO activation or unstable regulation. The EN/UVLO pin has a 1.14 V rising threshold, but system-level input must remain ≥4.5 V for proper buck operation and USB functionality.
What package variant does TPS25832QWRHBRQ1 use, and why are wettable flanks important?
TPS25832QWRHBRQ1 uses the RHB0032AA 32-pin VQFN package (5.00 mm × 5.00 mm) with wettable flanks. Wettable flanks enable automated optical inspection (AOI) of solder joints on the side walls-critical for automotive manufacturing quality assurance and zero-defect reliability requirements in safety-critical systems.
