STUSB4710AQ1TR

STUSB4710AQ1TR is STMicroelectronics’ USB Type-C Port Controller with Power Delivery negotiation. It handles CC line detection and orientation, manages USB-C port role (source/ sink/ dual‑role), and exchanges PD messages to control VBUS. The device is MCU‑driven via an I2C interface, with programmable current advertisement and DRP support, and it includes protection features (overcurrent, overvoltage, short‑circuit, thermal). It is designed to drive a Type‑C port in a variety of configurations, making it suitable for USB‑C chargers, adapters, hubs, and portable devices. The suffix AQ1 indicates automotive qualification (AEC‑Q100), and TR denotes Tape & Reel packaging. Use case: pair STUSB4710 with the PD power path FETs and a microcontroller to implement USB‑C PD functionality in devices or automotive accessories.

Functional/compatible alternatives to the STUSB4710AQ1TR include ST’s own STUSB4700/STUSB4711 (same family), ON Semiconductor FUSB302, Texas Instruments TUSB320 (and related TUSB PD controllers), and Infineon/Cypress CYPD317x series (e.g., CYPD3171). Verify pinout, PD revision, power handling and AEC-Q100/automotive qualification before substituting.

STUSB4710AQ1TR is a 16-pin device (16-pin VFQFPN / QFN package). Its primary functions:
- USB Type‑C port controller and USB‑PD policy engine (supports power‑role and data‑role management)
- CC1/CC2 pins for cable detection, plug orientation and Rp/Rd resistor control
- VBUS sensing and VBUS discharge/FET control (power‑path/enable signals)
- VCONN control (switching/power to cable)
- Host interface (I²C for configuration/status) plus interrupt/status output(s)
- Supply (VDD) and ground pins and several GPIOs/logic control pins for system integration
(Concise summary — consult the ST datasheet for full pin‑out names and electrical details.)

- Manufacturer: STMicroelectronics (ST).
- What kind of company: A global, European multinational semiconductor company that designs and manufactures a broad range of integrated circuits and semiconductor solutions (e.g., MCUs, analog, power, sensors) for electronics.

STUSB4710AQ1TR is the automotive-qualified STUSB4710A supplied in a small QFN (surface-mount) package and shipped in Tape & Reel (TR) format. For exact dimensions and pin count, see the STUSB4710A datasheet.
