Product details
Overview
TPS25830QWRHBRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive USB Type-C® and BC1.2 charging port controller with integrated synchronous step-down 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 integrates high-bandwidth DP/DM analog switches for USB 2.0 pass-through in infotainment head units.
For engineers reviewing the TPS25830QWRHBRQ1 datasheet, TPS25830QWRHBRQ1 pinout, TPS25830QWRHBRQ1 application, or TPS25830QWRHBRQ1 equivalent, key selection criteria include its 32-pin QFN wettable flank package, dual-mode current limiting (average buck or external NFET), USB-IF Rev 1.3 compliance, and absence of NTC/thermal warning features-distinguishing it from the TPS25831-Q1 variant.
Technical Context
The TPS25830QWRHBRQ1 implements 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 handles 3-A/1.5-A Type-C current advertisement and BC1.2 CDP/SDP detection without DCP auto-mode support.
It integrates dedicated high-bandwidth analog switches on DP_IN/DP_OUT and DM_IN/DM_OUT (RDS(on) ≤ 7.7 Ω max), enabling full-speed USB 2.0 data pass-through, while omitting NTC input and thermal warning flag-features exclusive to TPS25831-Q1 per device comparison table.
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 (4.5 V) and load-dump (36 V) conditions. |
| Output Voltage | 5.1 V ±1% - precision-regulated VBUS for USB Type-C and BC1.2 compliant charging. |
| Max Output Current | 3.5 A - continuous regulated current into VBUS, with cycle-by-cycle peak limit (HS: 4.6–6.2 A). |
| Cable Compensation | Up to 1.5 V - linear VBUS boost vs. load current counteracts voltage drop across long automotive cables. |
| Switching Frequency | 300 kHz to 2.2 MHz - user-selectable via RT/SYNC resistor or external clock; avoids AM band above 2.1 MHz. |
| USB Data Path | High-bandwidth DP/DM analog switches - supports USB 2.0 full-speed (480 Mbps) pass-through with <7.7 Ω RDS(on). |
| ESD Protection | ±8 kV contact / ±15 kV air (IEC 61000-4-2) on CC1, CC2, DP_IN, DM_IN - meets automotive EMC robustness requirements. |
Pinout & Package
TPS25830QWRHBRQ1 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 (1,2,3) | Power Input | Primary HV input for buck regulator; requires local high-quality bypass capacitors to PGND. |
| SW (28–31) | Power Switch Node | Connection point for external power inductor; ties to source of HS FET and drain of LS FET. |
| CSN/OUT (13) | Buck Output / Sense− | Regulated 5.1-V VBUS output and negative current sense input for cable compensation and current limiting. |
| CSP (14) | Current Sense+ | Positive current sense input; voltage difference vs. CSN/OUT sets average current limit threshold. |
| DP_IN (18), DM_IN (17) | USB Host Data In | Connects to Type-C receptacle DP/DM lines; routed through internal analog switches to host controller. |
| DP_OUT (7), DM_OUT (8) | USB Host Data Out | Connects to USB host controller; completes full-speed USB 2.0 data path with low RDS(on). |
| CC1 (20), CC2 (19) | Type-C Configuration Channel | Analog I/O pins for CC logic, VCONN sourcing/discharge, and cable polarity detection (POL). |
| RT/SYNC (9) | Freq Control | Resistor-to-ground sets switching frequency; driven by external clock to synchronize multiple regulators. |
| EN/UVLO (4) | Enable / UVLO Input | Logic-level enable with precision UVLO thresholds (1.14 V rise, 0.3 V fall); supports resistor-divider biasing. |
| FAULT (24) | Fault Flag | Active-low open-drain output signaling overcurrent, overvoltage, short-to-battery, or overtemperature events. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated USB Type-C & BC1.2 Controller | Handles 3-A/1.5-A current advertisement, CDP/SDP detection, and VCONN management-no external MCU required. |
| Cable Droop Compensation | Adjustable up to 1.5 V via IMON resistor; maintains stable VBUS at portable device connector under 3.5-A load. |
| Dual Current Limit Architecture | Supports either internal average-current limiting (via RILIMIT) or external NMOS-based fault-tolerant limiting (via LS_GD). |
| High-Bandwidth USB 2.0 Switches | DP/DM pass-through with RDS(on) ≤ 7.7 Ω ensures minimal signal degradation for full-speed USB 2.0 operation. |
| Automotive-Grade Protection | Includes VBUS short-to-VBAT, CC/DP/DM short-to-VBAT/VBUS, hiccup short-circuit, and ±15-kV air-gap ESD protection. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB-C automotive port controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS25831QWRHBRQ1 | Includes NTC input, thermal warning flag, and DCP auto-mode; lacks DP/DM switches. | Preferred for thermally constrained environments requiring intelligent thermal management; unsuitable where USB 2.0 data pass-through is needed. | Select TPS25831QWRHBRQ1 only if thermal monitoring is required and DP/DM switching is unnecessary. |
| TPS65987DQWRJURQ1 | USB-C PD controller with programmable 5–20 V output, no integrated buck regulator, requires external power stage. | Supports full USB Power Delivery (up to 100 W); used in bidirectional, high-power applications like display docks-not for fixed 5-V/3.5-A charging. | Choose TPS65987DQWRJURQ1 when variable VBUS, sink/source capability, or >5 V output is required. |
Compared with TPS25830QWRHBRQ1, TPS25831QWRHBRQ1 trades DP/DM switching for thermal sensing, while TPS65987DQWRJURQ1 replaces the integrated buck with flexible PD protocol handling-neither offers pin-compatible replacement, and each serves distinct system-level power architecture needs.

FAQ
What is the primary function of the TPS25830QWRHBRQ1 in an automotive USB-C system?
The TPS25830QWRHBRQ1 serves as a complete automotive-qualified USB Type-C and BC1.2 charging port controller with an integrated 3.5-A synchronous buck regulator. It regulates 5.1 V ±1% VBUS, negotiates power roles via CC logic, enables USB 2.0 data pass-through using internal DP/DM analog switches, and applies cable droop compensation up to 1.5 V-ensuring stable charging at the connected device regardless of cable length or load current.
Does the TPS25830QWRHBRQ1 support USB Power Delivery (USB-PD) protocol negotiation?
No, the TPS25830QWRHBRQ1 does not support USB Power Delivery (USB-PD) protocol negotiation. It complies with USB Type-C Rev 1.3 for fixed 5-V operation and BC1.2 for legacy USB charging signatures (CDP/SDP), but lacks the BMC PHY, PD controller, and variable-voltage regulation required for USB-PD. For USB-PD, TI recommends TPS65987DQWRJURQ1 or TPS65988.
How does cable droop compensation work in the TPS25830QWRHBRQ1?
Cable droop compensation in the TPS25830QWRHBRQ1 adjusts the buck regulator's output voltage upward in proportion to load current using a precision current-sense amplifier (CSP–CSN/OUT). The IMON resistor sets the compensation slope, allowing up to 1.5 V of linear boost-counteracting voltage loss across automotive cabling so that VBUS measured at the connected device remains near 5.1 V even at 3.5-A load.
What is the purpose of the LS_GD pin on the TPS25830QWRHBRQ1?
The LS_GD pin on the TPS25830QWRHBRQ1 drives the gate of an external NMOS transistor to implement fault-tolerant current limiting. When configured for external NFET mode, LS_GD provides 9.5–12.5 V gate drive with 20–50 µA sink current, enabling the buck regulator to continue powering other loads during a USB port overcurrent event-unlike internal average-current limiting which shuts down the entire output.
Is the TPS25830QWRHBRQ1 pin-compatible with the TPS25831QWRHBRQ1?
No, the TPS25830QWRHBRQ1 is not pin-compatible with the TPS25831QWRHBRQ1. Although both use the same 32-pin VQFN package, their pin functions differ: TPS25830QWRHBRQ1 assigns DP_OUT (7) and DM_OUT (8), while TPS25831QWRHBRQ1 uses those pins for THERM_WARN (7) and NTC (8). Swapping them without board revision will cause functional failure.
