Product details
Overview
TPS25830QCWRHBRQ1 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 across 4.5–36 V input, features cable droop compensation up to 1.5 V, and includes high-bandwidth DP/DM analog switches for USB 2.0 pass-through in infotainment head units.
For engineers reviewing the TPS25830QCWRHBRQ1 datasheet, TPS25830QCWRHBRQ1 pinout, TPS25830QCWRHBRQ1 application, or TPS25830QCWRHBRQ1 equivalent, key selection criteria include its 32-pin wettable-flank QFN package, dual-mode current limiting (internal avg. limit or external NFET), CC logic with VCONN sourcing, and USB-IF-compliant Type-C Rev 1.3 implementation - all qualified for –40°C to +125°C operation.
Technical Context
The TPS25830QCWRHBRQ1 integrates a current-mode-controlled synchronous buck regulator with internal compensation and adjustable switching frequency (300 kHz–2.2 MHz), synchronized via RT/SYNC pin. Its USB subsystem implements full CC logic for 3-A/1.5-A advertisement, polarity detection (POL), and legacy BC1.2 CDP/SDP mode support - but excludes DCP auto-detection and NTC thermal sensing, distinguishing it from the TPS25831-Q1 variant.
It provides dedicated high-bandwidth analog switches on DP_IN/DP_OUT and DM_IN/DM_OUT (RDS(on) ≤ 7.7 Ω), enabling USB 2.0 data pass-through without signal degradation. Protection architecture includes VBUS short-to-VBAT, CC/DP/DM short-to-VBAT/VBUS, IEC 61000-4-2 ±8-kV contact / ±15-kV air ESD rating on interface pins, and active-low fault reporting via FAULT pin.

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 |
|---|---|---|---|
| TPS25831QWRHBRQ1 | Includes DCP auto-detection, NTC input, and THERM_WARN flag; lacks DP/DM switches. | Preferred for thermally constrained modules requiring intelligent thermal management; unsuitable where USB 2.0 data pass-through is needed. | Select TPS25831-Q1 when thermal monitoring is critical and DP/DM switching is unnecessary. |
| TPS65987DQXR | Supports USB Power Delivery 3.0 (up to 100 W), programmable policy engine, and dual-role port; no integrated buck regulator. | Requires external 5 V supply or companion DC/DC; targets high-power laptop docks and multi-port hubs, not 5 V–only automotive ports. | Choose TPS65987D only when USB PD negotiation, higher power, or dual-role capability is required. |
Compared with TPS25831-Q1, TPS25830QCWRHBRQ1 prioritizes USB 2.0 signal integrity over thermal sensing; compared with TPS65987D, it embeds the buck regulator and simplifies BOM for fixed 5 V/3.5 A applications - reducing cost and layout complexity in entry-level automotive USB-C ports.

FAQ
What is the primary function of the TPS25830QCWRHBRQ1 in an automotive USB-C port?
The TPS25830QCWRHBRQ1 serves as a fully integrated USB Type-C® and BC1.2 charging port controller with an onboard synchronous buck regulator. It delivers regulated 5.1 V at up to 3.5 A, manages CC logic for current advertisement and plug orientation, provides VCONN power, and routes USB 2.0 DP/DM signals through high-bandwidth analog switches - all within a single AEC-Q100 Grade 1 device. This eliminates discrete components in automotive infotainment USB-C implementations.
Does the TPS25830QCWRHBRQ1 support USB Power Delivery (PD) negotiation?
No, the TPS25830QCWRHBRQ1 does not support USB Power Delivery (PD) negotiation. It complies with USB Type-C® Rev 1.3 for fixed 5 V operation and implements BC1.2 CDP/SDP modes for legacy device compatibility. It advertises only 3 A or 1.5 A via CC logic and lacks the policy engine, BMC transceiver, or VCONN programmability required for USB PD communication. For PD support, TI recommends the TPS65987D series instead of the TPS25830QCWRHBRQ1.
How does cable droop compensation work in the TPS25830QCWRHBRQ1?
Cable droop compensation in the TPS25830QCWRHBRQ1 uses a precision current-sense amplifier to monitor load current via the CSP–CSN/OUT differential voltage. The IMON pin outputs a voltage proportional to this current, which is fed back to adjust the buck regulator's reference - increasing VBUS linearly with load to counteract IR drop. With RIMON = 13 kΩ, full-scale compensation reaches 1.5 V, ensuring the connected device sees stable 5 V even over long automotive cables carrying 3.5 A.
What protection features are integrated into the TPS25830QCWRHBRQ1?
The TPS25830QCWRHBRQ1 integrates VBUS short-to-VBAT protection, CC1/CC2/DP_IN/DM_IN short-to-VBAT and short-to-VBUS protection, cycle-by-cycle current limiting, hiccup-mode short-circuit protection, undervoltage lockout, VBUS overvoltage protection (7.5 V threshold), and die overtemperature shutdown. Its interface pins meet IEC 61000-4-2 with ±8 kV contact and ±15 kV air discharge ratings - making it suitable for harsh automotive environments where ESD and electrical overstress are common failure modes.
Can the TPS25830QCWRHBRQ1 be used without external current-sense resistors?
Yes, the TPS25830QCWRHBRQ1 supports internal current sensing for its buck regulator using the CSP and CSN/OUT pins - no external sense resistor is required for basic operation. However, external resistors RILIMIT (on ILIMIT pin) and RIMON (on IMON pin) are mandatory to set the current limit threshold and cable compensation gain, respectively. The device's internal sense path relies on the MOSFET's RDS(on) and internal amplifiers calibrated across temperature, eliminating the need for a separate shunt.
