Product details
Overview
TUSB8020BIPHPQ1 from Texas Instruments is an AEC-Q100 qualified two-port USB 3.0 hub IC designed for automotive console and convenience port applications. It supports simultaneous SuperSpeed (5 Gbps), high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) USB connectivity on downstream ports, with integrated MTT architecture, per-port/ganged power switching, and USB Battery Charging 1.2 CDP/DCP compliance.
For engineers reviewing the TUSB8020BIPHPQ1 datasheet, TUSB8020BIPHPQ1 pinout, TUSB8020BIPHPQ1 application, or TUSB8020BIPHPQ1 equivalent, key selection considerations include automotive temperature range (–40°C to 85°C), HTQFP-48 package compatibility, SuperSpeed upstream/downstream signal integrity requirements, and battery charging mode configuration via PWRCTL/BATEN pins or registers.
Technical Context
The TUSB8020BIPHPQ1 implements a Multi-Transaction Translator (MTT) hub architecture with four asynchronous endpoint buffers per TT, enabling concurrent high-bandwidth transfers across USB 2.0 devices on each downstream port. Its dual-mode upstream interface dynamically disables SuperSpeed or high-speed functionality based on host capability-retaining USB 2.0 operation when connected to legacy hosts.
Power management is implemented through configurable per-port or ganged control using PWRCTL1/PWRCTL2 and OVERCUR1z/OVERCUR2z signals, with polarity selectable via PWRCTL_POL. Battery charging support includes CDP mode (upstream-connected), DCP mode (upstream-unconnected, compliant with YD/T 1591-2009), and AUTOMODE for automatic divider/DCP selection based on attached device detection.

FAQ
What is the operating temperature range of the TUSB8020BIPHPQ1?
The TUSB8020BIPHPQ1 is rated for –40°C to +85°C and qualified per AEC-Q100 Grade 2, making it suitable for under-dash, center-console, and other automotive interior environments where thermal cycling and long-term reliability are critical. Junction temperature must remain ≤105°C under all operating conditions, and thermal design should account for RθJA = 31.8°C/W on JEDEC-standard boards.
Does the TUSB8020BIPHPQ1 support USB Battery Charging Specification 1.2?
Yes, the TUSB8020BIPHPQ1 fully supports USB Battery Charging Specification Revision 1.2, including Charging Downstream Port (CDP) mode when the upstream port is connected, and Dedicated Charging Port (DCP) mode when unconnected. DCP mode complies with both BC 1.2 and Chinese standard YD/T 1591-2009, and AUTOMODE enables automatic selection between divider and DCP modes based on attached device detection.
How is power management configured on the TUSB8020BIPHPQ1?
Power management on the TUSB8020BIPHPQ1 is configured via register REG_5h (fullPwrMgmtz and ganged bits) or hardware strapping pins FULLPWRMGMTz and GANGED. Per-port or ganged control is supported, with active-high/low polarity selectable via PWRCTL_POL or REG_Ah(pwrctlPol). Over-current detection uses OVERCUR1z/OVERCUR2z inputs, and fault reporting differs between individual and ganged modes per TI SLLSEF7 Section 6.
Can the TUSB8020BIPHPQ1 be configured without external EEPROM or I²C host?
Yes, the TUSB8020BIPHPQ1 supports One-Time Programmable (OTP) ROM for permanent configuration of VID/PID, port removability, automode enable, and high-current divider mode. OTP programming is performed via vendor-defined USB requests and does not require external memory or I²C interface-ideal for high-volume automotive production where BOM simplification and boot-time determinism are essential.
What clock source options does the TUSB8020BIPHPQ1 support?
The TUSB8020BIPHPQ1 accepts either a 24-MHz fundamental-mode crystal (12–24 pF load capacitance, ≤50 Ω ESR, ±100 ppm stability) or a 24-MHz CMOS oscillator input. When using a crystal, a 1-MΩ feedback resistor between XI and XO is required, and traces must be short and shielded from noise sources. Oscillator input requires XI tied to 1.8 V and XO left floating.
