Product details
Overview
TPS25830AQCWRHBRQ1 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 across 4.5–36 V input range. It provides cable droop compensation up to 1.5 V, high-bandwidth DP/DM analog switches, and CC logic with VCONN sourcing-designed for USB media hubs and infotainment systems requiring robust short-to-battery protection on VBUS, CC1, CC2, DP_IN, and DM_IN.
For engineers reviewing the TPS25830AQCWRHBRQ1 datasheet, TPS25830AQCWRHBRQ1 pinout, TPS25830AQCWRHBRQ1 application, or TPS25830AQCWRHBRQ1 equivalent, key selection criteria include its 32-pin VQFN wettable flank package, dual current-limit architecture (buck + external NFET), MFI overcurrent compliance, client-mode firmware update support, and integrated short-to-VBAT protection on data and CC lines-critical for automotive USB power delivery integrity.
Technical Context
The TPS25830AQCWRHBRQ1 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 rev 1.3 CC logic, polarity detection (POL), DCP/SDP mode per BC1.2, and high-bandwidth analog switches (RDS(ON) = 3.4–6.3 Ω) for DP/DM pass-through.
It features dual-path protection: VBUS short-to-VBAT, plus pin-specific short-to-VBAT on CC1, CC2, DP_IN, and DM_IN (exclusive to TPS25830A-Q1), alongside IEC 61000-4-2 ±8-kV contact / ±15-kV air ESD rating on those pins. Fault reporting is provided via active-low open-drain FAULT, LD_DET, and POL outputs.
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% - precision regulation ensures stable USB VBUS for compliant device charging. |
| Max Output Current | 3.5 A - sufficient for dual-port USB-C PD sink or high-power legacy BC1.2 charging. |
| Cable Compensation | Up to 1.5 V linear compensation - maintains constant VBUS at device end under heavy load, countering automotive cable IR drop. |
| Switching Frequency | 300 kHz to 2.2 MHz - adjustable via RT/SYNC pin; enables optimization for efficiency (≤400 kHz) or EMI (≥2.1 MHz). |
| Short-to-VBAT Protection | On VBUS, CC1, CC2, DP_IN, DM_IN - prevents latch-up and damage during battery fault conditions in vehicle harnesses. |

Pinout & Package
TPS25830AQCWRHBRQ1 uses a 32-pin VQFN (RHB0032AA) package with 5.0 mm × 5.0 mm body size and wettable flanks for automated optical inspection. Thermal pad is electrically connected to PGND.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN (1–3) | Power input | High-current input path for buck regulator; requires low-ESR bulk capacitance directly to PGND. |
| SW (28–31) | Switch node | Connection point for external inductor; ties HS-FET source and LS-FET drain; high di/dt node requiring tight layout. |
| CSN/OUT (13) | Buck output & current sense negative | Regulated 5.1-V VBUS output; also serves as current-sense reference for buck loop and cable compensation. |
| CSP (14) | Current sense positive | Senses voltage across external sense resistor (RSNS); sets average current limit and cable comp gain. |
| CC1 / CC2 (19–20) | Type-C configuration channel | Analog I/O for USB-C plug orientation detection, current advertisement (3-A/1.5-A), and VCONN sourcing/discharge. |
| DP_IN / DM_IN (17–18) | USB data line inputs | Accept differential signals from USB-C receptacle; include short-to-VBAT and IEC 61000-4-2 protection. |
| DP_OUT / DM_OUT (7–8) | USB data line outputs | Drive host-side USB PHY; feature high-bandwidth analog switches (RDS(ON) ≤6.3 Ω) for minimal signal degradation. |
| RT/SYNC (9) | Frequency control | Resistor-to-ground sets switching frequency; externally driven clock overrides to synchronize multiple regulators. |
| FAULT (24) | Fault indicator | Active-low open-drain flag asserted on overcurrent, overvoltage, overtemperature, or short-circuit events. |
| LS_GD (10) | NFET gate driver | Drives external NMOS for secondary current limiting; supports continued 5-V supply to non-USB loads during USB fault. |
Key Features
| Feature | Design Value |
|---|---|
| MFI overcurrent compliance | Meets Apple's latest MFI OC requirement via dual-threshold current limit circuitry and precise CSP–CSN/OUT sensing. |
| Client-mode firmware update | Enables in-system USB firmware updates without host controller intervention-reducing BOM and enabling field upgrades. |
| VBUS short-to-VBAT protection | Prevents catastrophic failure when VBUS shorts to 12/24-V battery rail-critical for automotive safety and reliability. |
| Integrated cable droop compensation | Linearly increases VBUS output by up to 1.5 V with load current, ensuring portable devices receive stable 5 V regardless of cable length/resistance. |
| Wettable flank QFN package | Enables automated AOI of solder joints on all 32 pins-improving manufacturing yield and long-term interconnect reliability in automotive environments. |

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 |
|---|---|---|---|
| TPS25832AQCWRHBRQ1 | Lacks short-to-VBAT protection on CC1/CC2/DP_IN/DM_IN; identical package, pinout, and core functionality. | Suitable where battery-fault isolation on data lines is not required-e.g., non-safety-critical accessory ports. | Select TPS25832AQCWRHBRQ1 only if VBAT short protection on CC/Dx is unnecessary; otherwise TPS25830AQCWRHBRQ1 is mandatory. |
| TPS65987DQVQR | Supports USB Power Delivery 3.0 (up to 100 W), includes integrated MCU and PD policy engine; no built-in buck regulator. | Requires external 5-V supply; targets high-power PD sink/source applications, not fixed 5-V/3.5-A charging ports. | Choose TPS65987DQVQR only when USB PD negotiation, variable VBUS, or >5-V output is needed; TPS25830AQCWRHBRQ1 is optimized for cost-sensitive 5-V fixed-output designs. |
Compared with TPS25832AQCWRHBRQ1, TPS25830AQCWRHBRQ1 adds critical short-to-VBAT protection on data and CC lines-enabling safer deployment in primary infotainment interfaces. Versus TPS65987DQVQR, it eliminates MCU complexity and external power stages, delivering lower BOM cost and higher integration for dedicated 5-V charging applications.

FAQ
What is the maximum supported cable droop compensation voltage for TPS25830AQCWRHBRQ1?
The TPS25830AQCWRHBRQ1 supports up to 1.5 V of linear cable droop compensation. This is achieved by adjusting the IMON resistor (RIMON) to scale the compensation voltage proportionally to load current, ensuring VBUS remains stable at the connected device despite IR losses in long automotive cables. The compensation voltage is clamped internally at 1.8 V when RIMON is left open.
Does TPS25830AQCWRHBRQ1 support USB Power Delivery (PD) protocol negotiation?
No, TPS25830AQCWRHBRQ1 does not implement USB PD communication or variable-voltage negotiation. It is a fixed 5.1-V USB-C sink controller compliant with USB Type-C rev 1.3 and BC1.2 standards-supporting 3-A and 1.5-A current advertisements via CC logic but not PD message exchange. For PD capability, TI recommends TPS65987DQVQR.
How does the short-to-VBAT protection work on CC1 and DP_IN pins in TPS25830AQCWRHBRQ1?
The TPS25830AQCWRHBRQ1 includes dedicated protection circuitry that detects and isolates CC1, CC2, DP_IN, and DM_IN pins when voltage exceeds 18 V relative to AGND-preventing latch-up or damage during battery rail faults. This protection is absent in TPS25832A-Q1 and is a key differentiator for primary infotainment USB ports exposed to vehicle electrical transients.
Can TPS25830AQCWRHBRQ1 operate without an external current-sense resistor?
No, TPS25830AQCWRHBRQ1 requires an external sense resistor (RSNS) between CSN/OUT and PGND for both buck current regulation and cable compensation. Typical value is 15 mΩ. Omitting RSNS disables current limiting, overcurrent protection, and cable compensation-rendering the device nonfunctional for its intended automotive USB charging role.
What is the purpose of the LS_GD pin on TPS25830AQCWRHBRQ1?
The LS_GD pin on TPS25830AQCWRHBRQ1 drives the gate of an external NMOS transistor to implement secondary current limiting. When the buck regulator enters overcurrent fault, LS_GD activates the NFET to divert current away from the USB port while maintaining 5-V output for other system loads-enabling graceful fault handling without full system shutdown.
