Product details
Overview
TUSB4041IPAPQ1 from Texas Instruments is an AEC-Q100 Grade-3 qualified four-port USB 2.0 hub IC for automotive systems, supporting high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) downstream connectivity, per-port/ganged power switching with overcurrent detection, and USB Battery Charging (BC) v1.2-compliant CDP/DCP modes including YD/T 1591-2009 compliance - deployed in infotainment head units and front console convenience ports.
For engineers reviewing the TUSB4041IPAPQ1 datasheet, TUSB4041IPAPQ1 pinout, TUSB4041IPAPQ1 application, or TUSB4041IPAPQ1 equivalent, key selection criteria include automotive temperature range (–40°C to 85°C), MTT architecture with four transaction translators, 64-pin HTQFP package with PowerPAD™, USB 2.0 upstream/downstream signal integrity, and OTP/I²C/SMBus configurability of VID/PID/port strings.
Technical Context
The TUSB4041IPAPQ1 implements a Multi-Transaction Translator (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 bandwidth contention. It supports dynamic USB speed negotiation: high-speed downstream operation is enabled only when the upstream port detects a high-speed host; otherwise, it falls back to full/low-speed mode.
Power management is configurable via hardware strapping (FULLPWRMGMTz, GANGED, PWRCTL_POL) or register control (REG_5h), supporting both per-port and ganged power switching with dedicated OVERCUR[4:1]z inputs. Battery charging logic operates autonomously using BATEN[4:1] strap pins and auto-mode detection (AUTOENz), delivering DCP divider-mode voltage profiles compliant with YD/T 1591-2009 without host software intervention.

FAQ
What is the operating temperature range for the TUSB4041IPAPQ1?
The TUSB4041IPAPQ1 is AEC-Q100 Grade-3 qualified with an ambient operating temperature range of –40°C to +85°C. This specification is validated per test conditions in the official TI datasheet SLLSEK4D, ensuring reliable operation in automotive cabin environments including dashboard, center console, and under-seat locations where thermal cycling and long-term stability are critical. The TUSB4041IPAPQ1 maintains full USB 2.0 functionality across this range without derating.
Does the TUSB4041IPAPQ1 support USB Battery Charging v1.2?
Yes, the TUSB4041IPAPQ1 supports USB Battery Charging v1.2 with CDP (Charging Downstream Port) mode when the upstream port is connected, and DCP (Dedicated Charging Port) mode when unconnected - including compliance with Chinese Telecommunications Industry Standard YD/T 1591-2009. It also provides automatic mode (AUTOENz) that dynamically selects between divider-mode and DCP based on attached device signature, all implemented in hardware without host CPU involvement. This functionality is confirmed in Section 6.3.1 of the TUSB4041IPAPQ1 datasheet.
What package type and pin count does the TUSB4041IPAPQ1 use?
The TUSB4041IPAPQ1 uses a 64-pin HTQFP (PAP) package measuring 12 mm × 12 mm with an exposed thermal pad. This package is explicitly listed in TI's official documentation (SLLSEK4D, Section 11) and features PowerPAD™ technology for enhanced thermal dissipation. The pinout includes dedicated USB differential pairs, power control signals (PWRCTL1–4/BATEN1–4), overcurrent inputs (OVERCUR1z–4z), and I²C/SMBus configuration interfaces - all verified in the Pin Configuration and Functions section (Figure 4-1 and Table 4-1).
Can the TUSB4041IPAPQ1 be configured without external EEPROM?
Yes, the TUSB4041IPAPQ1 supports configuration via pin strapping (e.g., FULLPWRMGMTz, GANGED, AUTOENz, PWRCTL_POL) at power-on reset, enabling basic functionality without external memory. For advanced customization - including VID/PID, manufacturer/product strings, and serial numbers - it supports one-time programmable (OTP) ROM, I²C EEPROM, or SMBus target interface. All three methods are documented in Sections 6.3.3 and 7.1 of the TUSB4041IPAPQ1 datasheet, with OTP programming performed through vendor-defined USB requests.
Is the TUSB4041IPAPQ1 compatible with USB Type-C connectors?
Yes, the TUSB4041IPAPQ1 supports USB Type-C compatibility through its DM/DP polarity swap feature, configurable via register (USB 2.0 Port Polarity Control Register) or hardware strap. This eliminates the need for external multiplexers when interfacing with Type-C receptacles, allowing direct connection of flipped USB 2.0 signals. The capability is specified in the Features list and detailed in Section 6.3.4 of the TUSB4041IPAPQ1 datasheet SLLSEK4D, confirming native support for Type-C mechanical orientation flexibility.
