Product details

Overview

TPS25832AQCWRHBRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive USB Type-C® and BC1.2 charging port controller with integrated 36-V input, 5.1-V/3.5-A synchronous buck regulator, cable droop compensation up to 1.5 V, and high-bandwidth DP/DM analog switches. It delivers stable VBUS under load for optimal portable device charging in infotainment systems.

For engineers reviewing the TPS25832AQCWRHBRQ1 datasheet, TPS25832AQCWRHBRQ1 pinout, TPS25832AQCWRHBRQ1 application, or TPS25832AQCWRHBRQ1 equivalent, key selection criteria include its 3.5-A regulated output, ±1% VBUS accuracy, 300 kHz–2.2 MHz adjustable switching frequency, USB-IF-compliant CC logic, and absence of DP/DM/CC short-to-VBAT protection compared to TPS25830A-Q1.

Technical Context

The TPS25832AQCWRHBRQ1 integrates a current-mode-controlled synchronous buck regulator with internal compensation and programmable frequency (300 kHz–2.2 MHz), enabling optimized efficiency and EMI performance. Its USB subsystem implements full Type-C rev 1.3 CC logic, BC1.2 DCP/SDP detection, and polarity (POL) reporting for cable orientation.

Cable compensation is implemented via precision current sensing (CSP/CSN/OUT pins) and user-programmable IMON/ILIMIT resistors, linearly adjusting VBUS to counteract up to 1.5 V IR drop. Unlike TPS25830A-Q1, it omits short-to-VBAT protection on CC1, CC2, DP_IN, and DM_IN-limiting its use to applications where that fault mode is externally managed.

Key Specifications

Parameter	Value and Actual Design Meaning
Input Voltage Range	4.5 V to 36 V - supports wide automotive battery range including cold-crank and load-dump transients.
Output Voltage	5.1 V ±1% - ensures USB compliance and stable charging voltage at connected device end.

DP_OUT / DM_OUT (7–8)	USB Data Output	High-fidelity outputs to host controller; R_DS(on) ≤ 6.3 Ω preserves signal integrity for USB 2.0 data rates.
RT/SYNC (9)	Frequency Control	Configurable as resistor-set oscillator (300 kHz–2.2 MHz) or external clock sync input for EMI reduction.
FAULT / LD_DET / POL (24, 23, 22)	Open-Drain Status Outputs	Active-low flags for fault conditions, UFP detection, and cable orientation-each pulled up externally.
LS_GD (10)	NFET Gate Driver	12.5-V capable driver for external NMOS current-limit switch; enables buck operation during USB overcurrent faults.

Key Features

Feature	Design Value
Integrated Synchronous Buck Regulator	Eliminates need for external DC/DC controller + MOSFETs; reduces BOM count and layout area while delivering 3.5-A continuous output.
User-Programmable Cable Compensation	Adjusts VBUS linearly with load current using IMON resistor, maintaining ≤±1% regulation at UFP regardless of cable length or gauge.
USB-IF Compliant Type-C Rev 1.3 Logic	Supports 3-A/1.5-A current advertisement, VCONN sourcing/discharge, and polarity detection-enabling full USB-C port functionality without firmware.
Two-Threshold Current Limit Architecture	Allows either internal average current limiting or external NFET-based limiting (via LS_GD), preserving 5-V supply to non-USB loads during USB port faults.
IEC 61000-4-2 ESD Protection	±8-kV contact / ±15-kV air discharge on CC1/CC2/DP_IN/DM_IN-meets automotive EMC requirements without external TVS diodes.

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
TPS25830A-Q1	Includes DP_IN/DM_IN/CC1/CC2 short-to-VBAT protection (up to 18 V); same package and pinout.	Suitable for designs requiring robust fault tolerance against battery shorts on data/cable lines.	Select TPS25830A-Q1 when short-to-battery protection on CC/DP/DM is mandatory per system safety analysis.
TPS65987D	USB PD 3.0 controller with programmable 5–20-V output, no integrated buck regulator; requires external DC/DC.	Enables variable-voltage PD charging (e.g., 9 V/15 V/20 V) but adds complexity and cost for fixed 5-V applications.	Choose TPS65987D only if USB Power Delivery beyond 5 V is required; otherwise TPS25832AQCWRHBRQ1 offers lower BOM cost and simpler design.

Compared with TPS25830A-Q1, TPS25832AQCWRHBRQ1 removes short-to-VBAT protection to reduce cost and die size while retaining identical USB functionality and buck performance; versus TPS65987D, it integrates the 5-V buck stage-eliminating external power components and simplifying layout for fixed-output automotive USB ports.

FAQ

What is the maximum supported cable compensation voltage for TPS25832AQCWRHBRQ1?

The TPS25832AQCWRHBRQ1 supports up to 1.5 V of cable droop compensation, achieved by programming the IMON resistor to scale the current-sense voltage (CSP–CSN/OUT) linearly with load current. This ensures VBUS remains within ±1% of 5.1 V at the connected device-even across long automotive cables with significant IR loss. The compensation voltage is clamped internally at 1.8 V when RIMON is left open.

Does TPS25832AQCWRHBRQ1 support USB Power Delivery (PD) beyond 5 V?

No, TPS25832AQCWRHBRQ1 does not support USB Power Delivery (PD) beyond 5 V. It is a fixed 5.1-V output USB Type-C and BC1.2 charging port controller with integrated synchronous buck regulator. For variable-voltage PD (e.g., 9 V, 15 V, 20 V), TI's TPS65987D or TPS65988 series are required-though those lack integrated DC/DC and demand external power stages.

How does TPS25832AQCWRHBRQ1 differ from TPS25830A-Q1 in protection features?

TPS25832AQCWRHBRQ1 omits short-to-VBAT protection on CC1, CC2, DP_IN, and DM_IN pins-unlike TPS25830A-Q1, which supports up to 18-V short-to-battery tolerance on those lines. This difference is explicitly documented in the device comparison table and functional description. All other protections-including short-to-VBUS, IEC 61000-4-2 ESD, overvoltage, and thermal shutdown-are retained in TPS25832AQCWRHBRQ1.

Can TPS25832AQCWRHBRQ1 operate without an external NMOS for current limiting?

Yes, TPS25832AQCWRHBRQ1 can operate without an external NMOS. Its internal current limit circuit uses the CSP–CSN/OUT differential voltage to regulate average output current up to 3.5 A. The LS_GD pin and external NMOS option provide an alternative current-limiting path-enabling continued 5-V supply to auxiliary loads during USB port overcurrent events-but is optional, not required for basic operation.

What is the purpose of the RT/SYNC pin on TPS25832AQCWRHBRQ1?

The RT/SYNC pin on TPS25832AQCWRHBRQ1 serves dual functions: as a resistor-connected timing input (300 kHz–2.2 MHz) for standalone frequency setting, or as a high-impedance synchronization input when driven by an external clock signal. When pulled above the PLL threshold, the internal oscillator amplifier disables and the pin accepts external clock edges-allowing EMI reduction via spread-spectrum dithering or synchronization to system clocks in multi-rail designs.
