Product details
Overview
TPS25772CQRQLRQ1 from Texas Instruments is an AEC-Q100 Grade 1 automotive dual-port USB Type-C® Power Delivery controller with integrated buck-boost regulator, supporting up to 65W per port, ±20mV VBUS output step resolution, and 300–450kHz switching frequency for in-vehicle charging and media hub applications.
For engineers reviewing the TPS25772CQRQLRQ1 datasheet, TPS25772CQRQLRQ1 pinout, TPS25772CQRQLRQ1 application, or TPS25772CQRQLRQ1 equivalent, key selection criteria include dual-port PPS compliance (TID: 9161), VIN range (5.5–18V), integrated ARM Cortex-M0 firmware control, and HotRod™ QFN-29 package with wettable flanks for automotive thermal and reliability validation.
Technical Context
The TPS25772CQRQLRQ1 implements a dual-channel USB PD 3.1 controller with independent CC logic, VCONN sourcing, and cable polarity detection for both Port A and Port B. Its integrated buck-boost converter uses four internal power switches and supports programmable PPS output (3.3–21V at ±20mV steps, 0–3A at ±50mA steps) with cable droop compensation and VBUS short-circuit protection to VBAT and GND.
It features an ARM Cortex-M0 microcontroller core enabling firmware-updatable power management, intelligent inter-port power sharing, and temperature- and supply-voltage-dependent derating. System-level protection includes short-circuit detection on Px_CC1/Px_CC2, Px_DP/Px_DM, and VBUS lines, plus enhanced ESD robustness per IEC61000-4-2 (±2kV contact/air) on critical USB interface pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VIN Range | 5.5V to 18V (40V absolute max); supports automotive battery transients and cold-crank conditions. |
| VBUS Output Range | 3.3V–21V with ±20mV DAC step size; enables precise PPS compliance for fast-charging smartphones and laptops. |
| Max Output Power | 65W per port; achieved via integrated buck-boost with four internal MOSFETs and adaptive peak current limiting. |
| Switching Frequency | 300/400/450kHz selectable; allows optimized EMI filtering and inductor sizing for space-constrained automotive PCBs. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-port USB PD controller applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPS25762CQRQLRQ1 | Single-port USB PD controller with identical buck-boost and firmware architecture; lacks Port B circuitry and associated pins (PB_CC1/PB_CC2/PB_DP/PB_DM). | Suitable only for single-port automotive designs; cannot support dual-device charging or redundancy. | Select when cost-sensitive single-port implementation is sufficient and board space must be minimized. |
| TPS25763DQRQLRQ1 | Single-port controller with DisplayPort Alt Mode support enabled; shares same RQL package and pinout subset but adds DP PHY and AUX channel logic. | Optimized for video-centric use cases (e.g., dashcam docking); does not provide second charging port or independent dual-PD policy engine. | Choose when DP Alt Mode is mandatory and dual-port charging is unnecessary-avoids unused silicon area and firmware overhead. |
Compared with TPS25762CQRQLRQ1 and TPS25763DQRQLRQ1, the TPS25772CQRQLRQ1 uniquely delivers true dual-port autonomy-each port independently negotiates PD contracts, applies cable droop compensation, and enforces thermal limits-making it the only option for concurrent high-power charging of two devices in automotive cabins.

FAQ
What USB Power Delivery specifications does the TPS25772CQRQLRQ1 support?
The TPS25772CQRQLRQ1 supports USB Type-C Power Delivery Revision 3.1 with Programmable Power Supply (PPS) functionality and is USB-IF certified (TID: 9161). It implements full PD messaging, VCONN sourcing, and cable polarity detection for both ports, and complies with BC1.2 legacy charging protocols including DCP, CDP, and SDP modes. The TPS25772CQRQLRQ1 does not support USB4 or Thunderbolt protocols.
Does the TPS25772CQRQLRQ1 support DisplayPort Alternate Mode?
No, the TPS25772CQRQLRQ1 does not support DisplayPort Alternate Mode. Unlike the TPS25763-Q1 variant, the TPS25772CQRQLRQ1 is configured exclusively for dual-port USB PD power delivery without DP PHY or AUX channel logic. Its PA_DP/PA_DM and PB_DP/PB_DM pins are reserved for BC1.2 D+/D− detection only-not high-speed DP data lanes.
What is the maximum continuous output current capability of the TPS25772CQRQLRQ1?
The TPS25772CQRQLRQ1 supports up to 3A continuous output current per port (IBUS) with ±50mA current limit step resolution. At VBUS = 20V, this enables 60W sustained delivery; with PPS fine-tuning and thermal management, peak 65W is achievable. Operation above 3A may trigger thermal shutdown depending on PCB layout, ambient temperature, and airflow-verified per RθJA = 33.3°C/W.
How is firmware updated on the TPS25772CQRQLRQ1?
Firmware updates for the TPS25772CQRQLRQ1 are performed via its primary I²C interface (I2C_SCL1/I2C_SDA1) using standard write commands to internal 32kB EEPROM. The ARM Cortex-M0 core supports in-field updates without reset interruption, preserving port state during patching. TI provides official firmware images and update utilities through its product folder and SDK documentation.
What protection features are integrated into the TPS25772CQRQLRQ1 for automotive environments?
The TPS25772CQRQLRQ1 integrates AEC-Q100 Grade 1 qualified protections including VBUS short-circuit to VBAT and GND, Px_CC1/Px_CC2 overvoltage clamping, Px_DP/Px_DM short detection, and enhanced connector-pin ESD (±2kV IEC61000-4-2 contact/air). It also features thermal shutdown (150°C TJ), VIN overvoltage lockout (19.2V), and undervoltage lockout (5.3V) with hysteresis-ensuring safe operation during automotive load-dump and cold-crank events.
