Product details
Overview
TPS25865QRPQRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified dual USB Type-A charging port controller integrating a synchronous buck DC/DC converter (5.5–26 V input, 5.1–5.4 V adjustable output), two precision USB power switches (7 mΩ RDS(ON), ±10% current limit at 2.73 A), and cable compensation (90 mV at 2.4 A). It delivers up to 2.4 A per port in automotive infotainment and center console charging systems.
For engineers reviewing the TPS25865QRPQRQ1 datasheet, TPS25865QRPQRQ1 pinout, TPS25865QRPQRQ1 application, or TPS25865QRPQRQ1 equivalent, key selection criteria include its 200–800 kHz adjustable switching frequency, thermal management via NTC-based load shedding, CISPR25 Class 5 EMI compliance, and support for BC1.2 DCP detection across both ports.
Technical Context
The TPS25865QRPQRQ1 implements peak-current-mode control with internal compensation, enabling stable regulation without external loop components. Its FPWM operation with spread-spectrum dithering reduces EMI peaks while maintaining deterministic timing for automotive noise-sensitive environments.
It integrates dual USB data-line signaling (PA_DP/PA_DM, PB_DP/PB_DM) for BC1.2 Shorted, 1.2-V, and Divider-3 mode detection, plus dedicated TS pin interface for external NTC thermistor-based thermal monitoring and programmable load shedding - all within a single 25-pin VQFN-HR package.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port USB charging controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS25864QRPQRQ1 | Supports 200 kHz–3 MHz switching frequency; lacks DCDC always-ON mode; identical pinout and feature set otherwise | Preferred where higher-frequency operation avoids AM band or enables smaller magnetics | Select TPS25864QRPQRQ1 when board layout requires >800 kHz switching or external clock synchronization above 800 kHz |
| TPS65988ARSLR | USB-C PD controller with integrated 3.3-V/1.2-V rails; no native USB-A BC1.2 support; requires external USB-A companion IC | Targets USB-C PD applications with programmable power delivery, not legacy USB-A charging | Choose TPS65988ARSLR only when upgrading to USB-C PD architecture; not a drop-in replacement for USB-A ports |
Compared with TPS25865QRPQRQ1, the TPS25864QRPQRQ1 offers broader frequency flexibility but omits DCDC always-ON functionality, while the TPS65988ARSLR serves a fundamentally different USB-C PD use case requiring additional components for USB-A compatibility.

FAQ
What is the maximum input voltage the TPS25865QRPQRQ1 can withstand without damage?
The TPS25865QRPQRQ1 can withstand up to 36 V on its IN pin without permanent damage, though normal operation is suspended above the 26-V overvoltage protection threshold. This robustness supports automotive load-dump transient immunity while maintaining functional regulation between 5.5 V and 26 V.
Does the TPS25865QRPQRQ1 support cable compensation on both USB ports simultaneously?
Yes, the TPS25865QRPQRQ1 applies cable compensation to both PA_BUS and PB_BUS outputs when configured for 5.17-V output (VSET shorted to GND). The 90-mV compensation voltage is active per port at 2.4-A load, ensuring stable BUS voltage at the connected device regardless of which port is active or both are loaded.
How is thermal management implemented in the TPS25865QRPQRQ1?
The TPS25865QRPQRQ1 uses an external NTC thermistor connected to the TS pin to monitor temperature. Based on the sensed voltage, it dynamically reduces USB output voltage (load shedding) before reaching 166 °C thermal shutdown. Trip thresholds are programmable via NTC selection and series resistor values.
Can the TPS25865QRPQRQ1 operate with a fixed 5.1-V output without using the VSET resistor network?
Yes - leaving the VSET pin floating or pulling it up to VSENSE configures the TPS25865QRPQRQ1 for nominal 5.1-V output with ±1% accuracy at 25 °C. No external resistors are required for this default setting, simplifying design for basic USB charging applications.
What USB Battery Charging standards does the TPS25865QRPQRQ1 support?
The TPS25865QRPQRQ1 fully complies with USB Battery Charging Specification Rev 1.2, supporting automatic detection of Shorted mode (BC1.2/YD/T 1591-2009), 1.2-V mode, and Divider-3 mode on both USB-A ports. It also supports Apple and Samsung proprietary charging schemes as documented in TI's application notes.
