Product details
Overview
TPS25762CAQRQLRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive USB Type-C® Power Delivery controller with integrated buck-boost regulator, supporting up to 65W output (3.3–21V @ ±20mV step, 0–3A @ ±50mA step), 300/400/450kHz switching frequency, and ARM® Cortex®-M0 microcontroller core for firmware-updatable power management in single-port automotive infotainment systems.
For engineers reviewing the TPS25762CAQRQLRQ1 datasheet, TPS25762CAQRQLRQ1 pinout, TPS25762CAQRQLRQ1 application, or TPS25762CAQRQLRQ1 equivalent, this device delivers certified USB PD 3.1 + PPS (TID: 9509), integrated VBUS short-circuit protection, cable droop compensation, BC1.2/DCP legacy charging support, and robust ESD resilience (±2kV HBM, ±2kV IEC61000-4-2 on CC/DP/DM/VBUS pins) for automotive USB charge and media hub designs.
Technical Context
The TPS25762CAQRQLRQ1 implements a fully integrated USB PD 3.1 protocol stack with programmable power supply (PPS) support, using an ARM Cortex-M0 core to manage real-time negotiation, dynamic voltage/current adjustment, and system-level thermal/battery transient response. Its dual-mode buck-boost topology employs four internal power switches and supports VIN from 5.5V to 18V (40V abs max), delivering regulated VBUS with ±20mV DAC resolution and precise current limiting (±50mA step).
It integrates CC logic, VCONN sourcing/discharge, USB 2.0 DP/DM data path, BC1.2 detection (2.7V divider-3, 1.2V divider, HV-DCP), and intelligent System Power Management (SPM) that adapts delivered power based on battery voltage, temperature, and load conditions - all within a HotRod™ QFN-29 (6.0 × 5.0 mm) package with wettable flanks for automotive-grade solder joint inspection.

Pinout & Package
TPS25762CAQRQLRQ1 uses a 29-pin HotRod™ QFN (RQL) package measuring 6.0 mm × 5.0 mm with wettable flanks for automated optical inspection. The package integrates high-current power paths (IN, PGND, SW1, SW2, OUT), precision analog sensing (CSP, CSN/BUS), dual I²C interfaces (SCL1/SDA1, SCL2/SDA2), and multifunction GPIOs with configurable roles including IRQ, SYNC, NTC, and USB data (PA_DP/PA_DM).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| IN | Main power input | Accepts 5.5–18V automotive supply; supports 40V transient tolerance with slew-rate control. |
| PGND | Power ground return | High-current return path for buck-boost FETs and LDOs; must be low-inductance connection to PCB ground plane. |
| SW1 / SW2 | Buck/boost switching nodes | Connect to external inductor; SW1 drives buck phase, SW2 drives boost phase in 4-switch topology. |
| OUT | VBUS output | Regulated USB PD output (3.3–21V); connects directly to Type-C connector VBUS via bulk capacitance. |
| CSP / CSN/BUS | Current sense inputs | Differential pair for accurate output current measurement; CSN/BUS also serves as VBUS feedback node. |
| PA_CC1 / PA_CC2 | Type-C configuration channel | Analog I/O for PD communication, VCONN sourcing, and cable orientation detection per USB Type-C spec. |
| PA_DP / PA_DM | USB 2.0 data path | BC1.2-compliant D+ and D− lines; support legacy charging detection and optional USB 2.0 signaling. |
| I2C_SCL1 / I2C_SDA1 | Primary I²C interface | Configures device settings, reads telemetry, and updates firmware; supports standard/fast-mode speeds. |
| GPIO5 (NTC) | Thermistor input | Monitors board/system temperature via NTC or PTC resistor; enables thermal derating of output power. |
| GPIO6 (SYNC) | Frequency synchronization | Provides clock-out (sync to external regulators) or accepts clock-in (sync internal switching to external source). |
Key Features
| Feature | Design Value |
|---|---|
| Integrated buck-boost with 4 power switches | Enables single-stage 3.3–21V VBUS generation from 5.5–18V input without external FETs or complex discrete power stages. |
| USB PD 3.1 + PPS compliance (TID: 9509) | Guarantees interoperability with certified PD sources/sinks and enables fine-grained voltage control (e.g., 9.5V @ 3A) for fast-charging smartphones/tablets. |
| VBUS cable droop compensation | Adjusts output voltage in real time based on measured current to maintain target VBUS at the connector, compensating for IR drop across cables. |
| System Power Management (SPM) Engine | Dynamically scales delivered power using onboard temperature, VIN, and load data - preventing thermal shutdown during sustained 65W operation. |
| HotRod™ QFN-29 with wettable flanks | Supports automated X-ray and AOI inspection of solder joints; improves reliability in automotive vibration and thermal cycling environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB PD controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS25772CAQRQLRQ1 | Two-port USB PD controller with identical buck-boost architecture and 65W/port capability; adds second CC logic block and DP Alt Mode support. | Suitable for dual-port head units or rear-seat systems requiring independent PD negotiation on two connectors. | Select when dual independent USB-C ports are required; not pin-compatible - requires PCB redesign and firmware adaptation. |
| FPF2290SMX | Single-port automotive USB switch with OVP/UVP/OC protection only; no PD protocol stack, no buck-boost, no firmware. | Limited to basic 5V/3A charging without PD negotiation, PPS, or variable voltage output. | Choose only for cost-sensitive non-PD applications where USB-C is used solely as a physical connector with fixed 5V supply. |
Compared with TPS25772CAQRQLRQ1, the TPS25762CAQRQLRQ1 offers lower system cost and smaller footprint for single-port designs, while retaining full USB-IF PPS certification and automotive thermal robustness; compared with FPF2290SMX, it delivers full PD 3.1 functionality but requires firmware integration and higher design effort.

FAQ
What USB Power Delivery specifications does the TPS25762CAQRQLRQ1 support?
The TPS25762CAQRQLRQ1 supports USB Type-C Power Delivery Revision 3.1 with Programmable Power Supply (PPS) and is USB-IF certified (TID: 9509). It implements full PD protocol negotiation, variable VBUS (3.3–21V), adjustable current (0–3A), and PPS step resolution of ±20mV in voltage and ±50mA in current - meeting all mandatory and optional requirements for automotive-grade PD sinks.
Does the TPS25762CAQRQLRQ1 require external MOSFETs for its buck-boost regulator?
No, the TPS25762CAQRQLRQ1 integrates all four power switches required for its buck-boost topology - eliminating the need for external high-side or low-side MOSFETs. This integration reduces solution size, simplifies layout, and improves reliability in automotive environments where component count directly impacts field failure rates.
How does the TPS25762CAQRQLRQ1 handle USB cable voltage droop?
The TPS25762CAQRQLRQ1 implements real-time cable droop compensation by measuring output current via CSP/CSN/BUS and dynamically increasing VBUS output voltage to offset IR loss across the cable. Gain settings (0.025–0.1V/A) allow tuning for different cable gauges and lengths, ensuring target voltage is maintained at the connected device.
Is the TPS25762CAQRQLRQ1 compatible with legacy USB charging protocols?
Yes, the TPS25762CAQRQLRQ1 supports Battery Charging Specification v1.2 (BC1.2), including DCP (Dedicated Charging Port), CDP (Charging Downstream Port), and SDP (Standard Downstream Port) detection modes. It also implements legacy fast-charge protocols such as 2.7V divider-3, 1.2V divider, and high-voltage DCP - ensuring compatibility with older smartphones and accessories.
What thermal performance can be expected from the TPS25762CAQRQLRQ1 in a typical automotive layout?
In a standard 4-layer PCB with 2 oz copper and 1-in² exposed thermal pad, the TPS25762CAQRQLRQ1 achieves RθJA = 33.3°C/W. At 65W output (20V/3.25A), junction temperature rise is ~216°C above ambient - so derating or airflow is required for continuous operation at max power. For 30W (15V/2A), rise is ~100°C, enabling reliable operation at 125°C ambient with minimal heatsinking.
