Product details
Overview
TUSB4041IPAPRG4 from Texas Instruments is a four-port USB 2.0 hub IC with Multi-Transaction Translator (MTT) architecture, supporting high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) downstream connectivity. It integrates per-port/ganged power switching, USB Battery Charging (CDP/DCP/Auto-mode), 128-bit UUID, and OTP/EEPROM/I²C/SMBus configurability. Used in docking stations and industrial monitors requiring robust USB expansion with charging support.
For engineers reviewing the TUSB4041IPAPRG4 datasheet, TUSB4041IPAPRG4 pinout, TUSB4041IPAPRG4 application, or TUSB4041IPAPRG4 equivalent, key selection criteria include MTT hub topology, battery charging compliance (YD/T 1591-2009), 64-pin HTQFP package thermal performance, and upstream/downstream speed negotiation behavior under varying VBUS conditions.
Technical Context
The TUSB4041IPAPRG4 implements a true Multi-Transaction Translator hub with four independent transaction translators and four asynchronous endpoint buffers per translator-enabling concurrent high-bandwidth transfers across all downstream ports without bandwidth contention. Its USB 2.0 compliance includes automatic upstream speed detection: high-speed downstream operation is enabled only when the upstream port detects a high-speed capable host; otherwise, it falls back to full/low-speed mode.
Power management is implemented via configurable PWRCTL[4:1]/BATEN[4:1] signals supporting active-high or active-low polarity (set by PWRCTL_POL), ganged or per-port control (GANGED pin), and overcurrent monitoring (OVERCUR1z–OVERCUR4z). Battery charging modes-CDP (upstream-connected), DCP (upstream-disconnected, YD/T 1591-2009 compliant), and Auto-mode (D+/D− divider + DCP auto-selection)-are controlled by register REG_6h and pin-strapped inputs like AUTOENz and BATENn.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Hub Architecture | Multi-Transaction Translator (MTT) with 4 independent TTs and 4 async endpoint buffers per TT - eliminates bandwidth bottlenecks in multi-device downstream scenarios. |
| USB Speed Support | Upstream: HS/FS/LS; Downstream: HS/FS/LS - HS enabled only if upstream detects HS-capable host; otherwise limited to FS/LS. |
| Supply Voltages | VDD = 0.99–1.26 V (1.1V nominal); VDD33 = 3.0–3.6 V - dual-rail operation enables low-power core logic and 3.3V I/O compatibility. |
| Battery Charging Modes | CDP (USB BC 1.2), DCP (YD/T 1591-2009 compliant), Auto-mode (D+/D− divider + DCP fallback) - supports legacy and modern charging protocols without host intervention. |
| Configuration Interface | OTP ROM, I²C EEPROM, SMBus target, or pin-strapping - enables VID/PID, port removability, manufacturer/product strings, and serial number customization. |
| Package & Thermal | 64-pin HTQFP (12 mm × 12 mm) with exposed thermal pad - RθJA = 26.2°C/W; supports industrial −40°C to +85°C ambient operation. |
| ESD Robustness | HBM ±4000 V, CDM ±1000 V - meets stringent system-level ESD requirements for docked peripherals and industrial enclosures. |
Pinout & Package
Package: 64-pin HTQFP (PAP) with exposed thermal pad (must be connected to PCB ground). Dimensions: 12 mm × 12 mm. Industrial temperature grade (−40°C to +85°C).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| USB_DP_UP / USB_DM_UP | Upstream differential pair | High-speed USB 2.0 interface to host controller; polarity-swappable via register control. |
| USB_DP_DN1–4 / USB_DM_DN1–4 | Downstream differential pairs | Four independent USB 2.0 ports; each supports HS/FS/LS negotiation based on upstream capability. |
| PWRCTL1–4 / BATEN1–4 | Port power/battery enable | Configurable active-high/low control (PWRCTL_POL) for per-port power switching and battery charging enable. |
| OVERCUR1z–4z | Overcurrent status inputs | Active-low open-drain signals indicating overcurrent fault on corresponding downstream port; used for automatic power cutoff. |
| SCL/SMBCLK & SDA/SMBDAT | I²C/SMBus interface | Configurable via SMBUSz pin; supports EEPROM programming, register access, and runtime configuration updates. |
| GRSTz | Global reset input | Active-low asynchronous reset; forces all internal registers to default state and halts USB functionality until deasserted. |
| XI / XO | Crystal oscillator interface | Accepts 24 MHz crystal (with 1 MΩ feedback resistor) or external 24 MHz clock source; no PLL required. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar USB 2.0 hub applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| USB2514B-AEZG | Single-transaction translator (STT) hub; no MTT; lower integration (no built-in battery charging logic or OTP). | Lacks native CDP/DCP/Auto-mode support; requires external charging IC or host-based charging control. | Select when cost sensitivity outweighs per-port bandwidth needs and battery charging is handled externally. |
| TUSB4041IRGZR | Same die, 48-pin VQFN package (7 mm × 7 mm); identical electrical specs but different thermal and layout constraints. | Smaller footprint and lower RθJA (22.5°C/W) but reduced thermal pad area; less suitable for sustained high-current charging applications. | Select for space-constrained consumer electronics where thermal load is moderate and PCB real estate is premium. |

FAQ
What USB speed modes does the TUSB4041IPAPRG4 support on its downstream ports?
The TUSB4041IPAPRG4 supports high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) on all four downstream ports. Downstream high-speed operation is conditionally enabled: it activates only when the upstream port detects a high-speed capable host; otherwise, downstream ports operate at full/low speed. This behavior is hardware-automated and requires no register configuration.
How does the TUSB4041IPAPRG4 implement USB Battery Charging (BC) compliance?
The TUSB4041IPAPRG4 natively supports CDP (USB BC 1.2), DCP (YD/T 1591-2009 compliant), and Auto-mode (D+/D− divider + DCP fallback) without external components. Battery charging mode per port is determined by BATEN[4:1] pin states and register REG_6h. Auto-mode automatically selects between divider-mode (fixed DC voltage on DP/DM) and DCP based on connected device signature.
Can the TUSB4041IPAPRG4 be configured without external memory?
Yes. The TUSB4041IPAPRG4 supports full pin-strapped configuration for critical features including battery charging enable (BATEN[4:1]), ganged vs. per-port power control (GANGED), I²C/SMBus mode (SMBUSz), and power control polarity (PWRCTL_POL). VID/PID and string customization require OTP, EEPROM, or I²C-but basic hub operation and charging are functional with pins alone.
What is the role of the USB_R1 pin on the TUSB4041IPAPRG4?
The USB_R1 pin on the TUSB4041IPAPRG4 is a precision reference input requiring a 9.53-kΩ ±1% resistor to ground. It calibrates internal current sources used for USB transceiver termination and battery charging detection circuitry-ensuring accurate D+/D− voltage divider ratios and reliable BC mode identification across process/voltage/temperature variations.
Does the TUSB4041IPAPRG4 require an external crystal, or can it use an oscillator?
The TUSB4041IPAPRG4 accepts either a 24 MHz crystal (between XI and XO pins, with 1 MΩ feedback resistor) or a 24 MHz CMOS oscillator driving the XI pin directly. XO may be left unconnected when using an external oscillator. No frequency multiplication or PLL is needed-the hub operates natively at 24 MHz for USB timing generation.
