Product details
Overview
TUSB8041IPAPQ1 from Texas Instruments is an AEC-Q100 qualified four-port USB 3.0 hub IC designed for automotive infotainment and telematics systems. It supports simultaneous SuperSpeed (5 Gbps), high-speed (480 Mbps), and full-speed (12 Mbps) USB connectivity on downstream ports, features per-port/ganged power switching with over-current detection, and operates across –40°C to +85°C.
For engineers reviewing the TUSB8041IPAPQ1 datasheet, TUSB8041IPAPQ1 pinout, TUSB8041IPAPQ1 application, or TUSB8041IPAPQ1 equivalent, key selection criteria include USB 3.0/2.0 dual-mode operation, battery charging support (CDP/DCP/Divider Mode), OTP/EEPROM/I²C configurability, and HTQFP-64 packaging with automotive-grade thermal and ESD robustness.
Technical Context
The TUSB8041IPAPQ1 integrates a USB 3.0 hub controller with Multi-Transaction Translator (MTT) architecture, enabling independent bandwidth allocation per downstream port. It implements dual-role upstream connectivity-accepting SuperSpeed, high-speed, or full-speed upstream links-and dynamically disables unsupported PHY layers (e.g., disables SuperSpeed when upstream is HS-only).
Its power management subsystem supports both individual port control (via PWRCTL1–4/BATEN1–4 pins) and ganged operation (controlled by GANGED pin), with dedicated OVERCUR1z–4z inputs for per-port over-current monitoring. Battery charging compliance includes CDP mode (upstream connected), DCP mode (upstream unconnected), and YD/T 1591-2009 standard support.

Pinout & Package
Package: 64-pin HTQFP (PAP), 10.00 mm × 10.00 mm body size, exposed thermal pad (THERM_AL_PAD) requiring connection to ground for thermal performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| OVERCUR1z–4z (Pins 14,15,12,11) | Per-port over-current sense input | Active-low open-drain inputs tied to external power switch fault outputs; assertion disables downstream port power |
| USB_SSTXP_UP / USB_SSTXM_UP (Pins 23,24) | Upstream SuperSpeed transmit differential pair | 5-Gbps differential output driving upstream host; requires controlled 90-Ω impedance routing |
| USB_SSRXP_DN1–DN4 (Pins 38,46,54,61) | Downstream SuperSpeed receive inputs | Four independent differential receivers supporting simultaneous SuperSpeed device attachment on each port |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB 3.0 hub applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TUSB8041IRGZT | Same die, commercial-grade (–40°C to +85°C not AEC-Q100 qualified); RGZ package (VQFN-64, 9×9 mm) | Lacks automotive qualification; unsuitable for safety-critical or under-hood deployments | Select only for non-automotive industrial or computing applications where AEC-Q100 is not required. |
| USB3320-EZK | USB 3.0 hub with integrated USB 2.0 transceivers; no SuperSpeed receiver/transmitter pins; supports only HS/FS/LS | Cannot support SuperSpeed peripherals; limited to USB 2.0 bandwidth (480 Mbps max aggregate) | Choose when system requirements exclude SuperSpeed devices and lower cost/footprint outweighs bandwidth needs. |
Compared with TUSB8041IPAPQ1, the TUSB8041IRGZT offers identical functionality but lacks AEC-Q100 validation and uses a smaller VQFN package, while the USB3320-EZK sacrifices SuperSpeed capability for reduced complexity and cost-making it suitable only for USB 2.0–centric designs.

FAQ
What is the operating temperature range of the TUSB8041IPAPQ1?
The TUSB8041IPAPQ1 is rated for operation from –40°C to +85°C ambient temperature and is AEC-Q100 Grade 2 qualified. Its thermal design supports junction temperatures up to 105°C, making it suitable for under-dash and center-console automotive locations where thermal management is constrained. This rating is verified per JEDEC JESD51-2a testing conditions.
Does the TUSB8041IPAPQ1 support USB Battery Charging (BC) 1.2 specification?
Yes, the TUSB8041IPAPQ1 fully supports USB BC 1.2 through native implementation of CDP (Charging Downstream Port) mode when the upstream port is connected, and DCP (Dedicated Charging Port) mode when upstream is unconnected. It also complies with Chinese YD/T 1591-2009 and supports automatic Divider Mode for legacy BC devices-all without external circuitry.
Can the TUSB8041IPAPQ1 operate with only USB 2.0 upstream connectivity?
Yes, the TUSB8041IPAPQ1 automatically detects upstream link capability: when only USB 2.0 (high-speed/full-speed) is present, it disables SuperSpeed PHY layers on all downstream ports and functions as a USB 2.0 hub with Multi-Transaction Translator (MTT) support. SuperSpeed remains disabled until a USB 3.0 upstream connection is established.
How is configuration handled on the TUSB8041IPAPQ1-does it require external memory?
The TUSB8041IPAPQ1 supports three configuration methods: factory-programmed OTP ROM (for immutable settings like VID/PID), external I²C EEPROM (for field-updatable parameters), or real-time I²C/SMBus slave interface (for dynamic runtime reconfiguration). No external memory is required if using OTP or pin-strapping for basic features like battery charging mode.
What package type and thermal characteristics does the TUSB8041IPAPQ1 use?
The TUSB8041IPAPQ1 uses a 64-pin HTQFP (PAP) package measuring 10.00 mm × 10.00 mm with an exposed thermal pad. Its thermal metrics include RθJA = 26.2°C/W (JEDEC high-K board), RθJB = 10.4°C/W, and ψJB = 10.3°C/W-enabling reliable operation in compact automotive enclosures without forced airflow or heatsinks.
