Product details
Overview
TUSB4020BIPHPRQ1 from Texas Instruments is an AEC-Q100 Grade-3 qualified two-port USB 2.0 hub IC for automotive systems, supporting high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) upstream/downstream connectivity, per-port or ganged power switching, and battery charging modes (CDP/DCP/YD/T 1591-2009 compliant) in a 48-pin HTQFP package.
For engineers reviewing the TUSB4020BIPHPRQ1 datasheet, TUSB4020BIPHPRQ1 pinout, TUSB4020BIPHPRQ1 application, or TUSB4020BIPHPRQ1 equivalent, key selection criteria include automotive temperature range (–40°C to 85°C), MTT architecture with four endpoint buffers per translator, 24 MHz clock input support, I²C/SMBus/OTP configurability, and USB Type-C compatibility with integrated VBUS monitoring and battery charging control logic.
Technical Context
The TUSB4020BIPHPRQ1 implements a Multi-Transaction Translator (MTT) hub architecture with two independent transaction translators and four asynchronous endpoint buffers per translator, enabling concurrent high-bandwidth transfers across downstream ports. It supports dynamic speed negotiation: high-speed operation on downstream ports is enabled only when the upstream port detects a high-speed capable host.
Power management is configurable via hardware strapping (GANGED, FULLPWRMGMTz, PWRCTL_POL) or register control, supporting both individual port power switching (with isolated overcurrent shutdown) and ganged operation (simultaneous power enable/disable). Battery charging mode selection (CDP, DCP, divider) is determined at reset by BATEN pins and register settings, with AUTOMODE enabling automatic DCP/divider switching based on attached device detection.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB Compliance | USB 2.0 specification compliant; supports high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) signaling on all ports. |
| Operating Temperature | AEC-Q100 Grade 3: –40°C to +85°C ambient, validated for automotive cabin and infotainment environments. |
| Supply Voltages | VDD = 1.1 V ±10% (core), VDD33 = 3.3 V ±10% (I/O); no strict power sequencing required between rails. |
| Power Management | Per-port or ganged power switching with dedicated OVERCUR1z/OVERCUR2z inputs; active-high/active-low polarity selectable via PWRCTL_POL. |
| Battery Charging | CDP mode (upstream connected), DCP mode (upstream unconnected, YD/T 1591-2009 compliant), and D+/D– divider mode; AUTOMODE enables automatic mode selection. |

| OVERCUR1z (5) | Port 1 Overcurrent Sense | Active-low input tied to external power switch fault output; triggers port-specific power disable in individual mode or hub-wide disable in ganged mode. |
| SCL/SMBCLK (2) & SDA/SMBDAT (3) | I²C/SMBus Interface | Selectable via SMBUSz pin: I²C EEPROM (SMBUSz=1) or SMBus target (SMBUSz=0); used for runtime configuration and firmware updates. |
| GANGED/SMBA2/HS_UP (35) | Mode Selection Input | Determines power control topology (0 = per-port, 1 = ganged) and reports upstream high-speed link status post-reset. |
| FULLPWRMGMTz/SMBA1 (36) | Power Management Enable | Enables/disables downstream port power switching (0 = enabled, 1 = disabled); also sets SMBus address bit 1 when SMBUSz=0. |

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 |
|---|---|---|---|
| TUSB4041IPRQ1 | Four-port USB 2.0 hub with identical MTT architecture, AEC-Q100 Grade 3 rating, and same 48-pin HTQFP package; adds third downstream port and additional configuration flexibility. | Requires PCB layout change for extra port routing; suitable when system needs >2 downstream connections without cascading hubs. | Select when expanding peripheral count beyond two ports while retaining automotive qualification and power management features. |
| USB2514B-AEZG-TR | Four-port USB 2.0 hub with MTT, but commercial-grade (–40°C to +85°C not AEC-Q100 certified); uses 48-pin QFN instead of HTQFP; lacks automotive-specific battery charging modes (YD/T 1591-2009). | Not qualified for automotive safety-critical or long-lifecycle deployments; limited to industrial or consumer docking applications. | Consider only for non-automotive designs where cost is prioritized over qualification, and battery charging compliance is unnecessary. |
Compared with TUSB4020BIPHPRQ1, the TUSB4041IPRQ1 offers scalable port count with identical automotive reliability and feature set, whereas the USB2514B-AEZG-TR provides higher port density at lower cost but sacrifices AEC-Q100 validation and automotive-specific charging protocols-making it unsuitable for production vehicle ECUs.

FAQ
What is the operating temperature range for the TUSB4020BIPHPRQ1?
The TUSB4020BIPHPRQ1 is AEC-Q100 Grade 3 qualified and operates from –40°C to +85°C ambient temperature. This range is validated for automotive cabin and infotainment applications, with junction temperature rated up to 105°C under normal operation and 125°C absolute maximum. Thermal design must account for RθJA = 31.8°C/W in the 48-pin HTQFP package.
Does the TUSB4020BIPHPRQ1 support USB Type-C connectors directly?
The TUSB4020BIPHPRQ1 is Type-C compatible but does not integrate native USB Type-C PHY or CC logic. It supports Type-C implementations via external multiplexers and CC detection circuits; its USB_DP/DM signals connect to standard USB 2.0 lanes routed through a Type-C receptacle. The device's VBUS monitoring and battery charging features align with Type-C power delivery expectations.
How is battery charging configured on the TUSB4020BIPHPRQ1?
Battery charging on the TUSB4020BIPHPRQ1 is configured via hardware strapping (PWRCTL1/BATEN1 and PWRCTL2/BATEN2 pins sampled at reset) or register writes (REG_6h batEn[1:0]). Supported modes include CDP (when upstream is connected), DCP (YD/T 1591-2009 compliant), and D+/D– divider mode. AUTOMODE enables automatic switching between DCP and divider modes based on attached device detection.
Can the TUSB4020BIPHPRQ1 be programmed in-system without removing it from the PCB?
Yes, the TUSB4020BIPHPRQ1 supports in-system programming via its USB 2.0 upstream port using vendor-defined USB requests. This enables field updates to OTP ROM contents-including VID/PID, port configurations, and manufacturer strings-without requiring socketed programming or board rework. I²C EEPROM and SMBus target interfaces also allow runtime configuration changes post-deployment.
What clock sources are supported by the TUSB4020BIPHPRQ1?
The TUSB4020BIPHPRQ1 accepts a 24 MHz fundamental-mode crystal connected between XI and XO pins, or a 24 MHz CMOS-compatible clock signal driven into the XI pin (with XO left unconnected). Crystal load capacitors CL1/CL2 are required; TI recommends 18 pF for typical 24 MHz crystals. Trace length matching and noise isolation from switching nodes are critical for jitter-sensitive USB timing.
