Product details
Overview
TUSB4041IPAPG4 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 (BC) 1.2-compliant CDP/DCP modes, and YD/T 1591-2009 DCP compliance for Chinese market applications. Designed for industrial temperature range (–40°C to 85°C), it serves as a core upstream aggregation point in docked computing systems.
For engineers reviewing the TUSB4041IPAPG4 datasheet, TUSB4041IPAPG4 pinout, TUSB4041IPAPG4 application, or TUSB4041IPAPG4 equivalent, key selection criteria include MTT-based transaction handling, battery charging mode configurability (CDP/DCP/AUTO), 64-pin HTQFP package thermal performance, and dual-supply operation (1.1V core / 3.3V I/O).
Technical Context
The TUSB4041IPAPG4 implements a true MTT hub architecture with four independent transaction translators and four asynchronous endpoint buffers per translator-enabling concurrent high-bandwidth transfers across all downstream ports without bottlenecking. Its USB 2.0 physical layer supports automatic speed negotiation: high-speed downstream operation is enabled only when the upstream port detects a high-speed host connection; otherwise, it falls back to full/low-speed only.
Power management is implemented via configurable PWRCTL[4:1]/BATEN[4:1] signals with selectable active-high/active-low polarity and ganged vs. per-port control modes, directly tied to register bits REG_5h(fullPwrMgmtz) and REG_5h(ganged). Battery charging logic operates independently of host enumeration, enabling DCP mode even with unconnected upstream VBUS, and auto-mode dynamically selects between D+D− divider and DCP based on attached device signature.

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-TT hub; no MTT; supports only one transaction translator shared across all ports | Limited concurrent bandwidth under multi-device load; no native DCP auto-mode or YD/T 1591-2009 compliance | Select when cost sensitivity outweighs multi-device throughput requirements and BC features are secondary |
| UPD720114GA-YF-BAC-A | 4-port MTT hub with integrated USB 2.0 PHY; requires external crystal; no built-in YD/T 1591-2009 DCP mode | Higher external component count; lacks auto-mode and Chinese standard compliance-requires host-side BC stack | Choose when leveraging Renesas' USB 3.0 companion chip ecosystem or needing integrated PHY for layout simplification |
Compared with USB2514B-AEZG and UPD720114GA-YF-BAC-A, the TUSB4041IPAPG4 uniquely delivers MTT-level concurrency, out-of-box YD/T 1591-2009 DCP compliance, and auto-mode charger detection-reducing firmware dependency and enabling drop-in integration in China-targeted consumer docks and adapters.

FAQ
What USB speeds does the TUSB4041IPAPG4 support on its downstream ports?
The TUSB4041IPAPG4 supports high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) on all four downstream ports. 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 only. This behavior is hardware-automated and requires no register configuration.
Does the TUSB4041IPAPG4 support USB Battery Charging specification v1.2?
Yes, the TUSB4041IPAPG4 fully supports USB Battery Charging specification v1.2, including Charging Downstream Port (CDP) mode when upstream is connected and Dedicated Charging Port (DCP) mode when upstream is unconnected. Its DCP implementation complies with Chinese Telecommunications Industry Standard YD/T 1591-2009, enabling certified fast charging for domestic smartphone models.
How is configuration stored on the TUSB4041IPAPG4 - OTP, EEPROM, or both?
The TUSB4041IPAPG4 supports multiple configuration storage methods: one-time programmable (OTP) ROM for permanent settings like VID/PID and port removability; external I²C EEPROM for field-updatable strings and custom configurations; and real-time SMBus host programming. OTP programming is performed via vendor-defined USB requests through the upstream port-no external programmer required.
What is the thermal performance of the TUSB4041IPAPG4 in its 64-pin HTQFP package?
The TUSB4041IPAPG4 in 64-pin HTQFP (PAP) package achieves a junction-to-board thermal resistance (Rθ JB) of 10.4°C/W and junction-to-ambient (Rθ JA) of 26.2°C/W. Its exposed PowerPAD™ thermal pad must be soldered to a solid PCB ground plane to realize this performance-enabling sustained 4-port high-speed operation at full industrial temperature range (–40°C to 85°C) without derating.
Can the TUSB4041IPAPG4 operate with only a 3.3V supply, or is the 1.1V rail mandatory?
The TUSB4041IPAPG4 requires both supplies: VDD33 (3.0–3.6 V) powers I/O and USB transceivers, while VDD (0.99–1.26 V) powers the 1.1V core logic. Both rails must be present and meet timing requirements-VDD must stabilize within 10 µs before VDD33 unless GRSTz is actively controlled. Omitting either supply will prevent functional operation or cause latch-up.
