Product details
Overview
TPS25858QRPQRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive-qualified dual-port USB Type-C® charging controller with integrated 6.6-A synchronous buck regulator, programmable current limit (±10% at 3.4 A), and thermal management via NTC thermistor interface. It delivers 5.1–5.4 V output across two 3-A USB ports and supports BC1.2 legacy charging for non-Type-C devices in vehicles.
For engineers reviewing the TPS25858QRPQRQ1 datasheet, TPS25858QRPQRQ1 pinout, TPS25858QRPQRQ1 application, or TPS25858QRPQRQ1 equivalent, key selection criteria include its CISPR25 Class 5 EMI compliance, HotRod™ QFN package, spread-spectrum switching, line-drop compensation (90 mV at 2.4 A), and integrated VCONN (200 mA) for USB3.1 peripherals.
Technical Context
The TPS25858QRPQRQ1 integrates a peak-current-mode-controlled synchronous buck converter (200–800 kHz adjustable frequency, FPWM with spread-spectrum dithering) and dual USB power path switches with independent CC logic for 3-A Type-C advertisement. Its internal 18-mΩ/10-mΩ HS/LS MOSFETs enable 94.5% efficiency at 13.5 VIN, 3 A per port.
It implements analog-based thermal load shedding using the TS pin connected to an external NTC thermistor, dynamically adjusting USB output voltage and current advertisement based on temperature. Unlike the TPS25859-Q1, it lacks individual port ON/OFF control and fault flag reporting-functions reserved for the companion variant.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port USB Type-C charging controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS25859QRPQRQ1 | Includes individual PA_EN/PB_EN port control and /PA_FAULT//PB_FAULT fault flags; no BC1.2 DCP support | Suitable where per-port enable/disable and fault reporting are required, but legacy BC1.2 compatibility is not needed | Select TPS25859QRPQRQ1 if system-level diagnostics and granular port management outweigh BC1.2 support needs |
| MPQ4282GQ-AEC1-Z | Single 3-A USB-C port controller with integrated buck; no dual-port or BC1.2 support; smaller 16-pin QFN | Applicable only for single-port designs; lacks Type-C 3-A advertisement and VCONN sourcing capability | Choose MPQ4282GQ-AEC1-Z only for cost-optimized single-port implementations where dual functionality is unnecessary |
Compared with TPS25858QRPQRQ1, the TPS25859QRPQRQ1 adds diagnostic granularity at the expense of BC1.2 compatibility, while MPQ4282GQ-AEC1-Z reduces integration depth and eliminates dual-port capability-making TPS25858QRPQRQ1 uniquely suited for automotive dual-port hubs requiring legacy device support and full Type-C feature parity.

FAQ
What is the maximum continuous output current per USB port supported by the TPS25858QRPQRQ1?
The TPS25858QRPQRQ1 supports up to 3 A continuous current per USB port (Port A and Port B), with programmable current limit accuracy of ±10% at 3.4 A. The device integrates dual 7-mΩ internal USB power switches and uses thermal monitoring via the TS pin to maintain safe operation under sustained load conditions.
Does the TPS25858QRPQRQ1 support USB Battery Charging (BC) 1.2 legacy detection?
Yes, the TPS25858QRPQRQ1 supports BC1.2 legacy charging modes including Shorted mode (per BC1.2 and YD/T 1591-2009), 1.2-V mode, and 2.7-V Divider 3 mode-enabling compatibility with non-Type-C devices such as older smartphones and accessories. This functionality is absent in the TPS25859-Q1 variant.
How does cable compensation work on the TPS25858QRPQRQ1, and when is it active?
Cable compensation on the TPS25858QRPQRQ1 provides a 90-mV voltage boost at 2.4-A load to counteract IR drop in automotive cabling-but only when the output voltage is set to 5.17 V (VSET shorted to GND). This ensures stable VBUS at the connected device, optimizing battery charging efficiency without requiring host-side compensation.
What package type and thermal performance does the TPS25858QRPQRQ1 use?
The TPS25858QRPQRQ1 uses a 25-pin VQFN-HR (RPQ) package measuring 3.50 mm × 4.50 mm with exposed thermal pad. Its thermal metrics include RθJA = 37.7°C/W and RθJB = 8.8°C/W, enabling reliable operation up to +150°C junction temperature in automotive under-hood or cabin environments.
Can the TPS25858QRPQRQ1 be synchronized to an external clock, and what is the supported frequency range?
Yes, the TPS25858QRPQRQ1 supports external clock synchronization via the FREQ/SYNC pin, accepting input clocks from 200 kHz to 800 kHz. This allows system-level EMI reduction through frequency alignment with other switching regulators and eliminates beat frequencies in multi-rail automotive power systems.
