Product details
Overview
TUSB4020BIPHPR from Texas Instruments is a two-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) USB connectivity on downstream ports. It features per-port/ganged power switching, battery charging support (CDP/DCP/AutoMode), and operates from 1.1V and 3.3V supplies in a 48-pin HTQFP package for industrial temperature range (–40°C to 85°C).
For engineers reviewing the TUSB4020BIPHPR datasheet, TUSB4020BIPHPR pinout, TUSB4020BIPHPR application, or TUSB4020BIPHPR equivalent, key selection criteria include USB 2.0 MTT hub functionality, Type-C compatibility, battery charging mode configurability (YD/T 1591-2009 compliant DCP), OTP/EEPROM/I²C programmability, and industrial-grade thermal performance (RθJA = 31.8°C/W).
Technical Context
The TUSB4020BIPHPR implements a dual-transaction-translator MTT hub architecture with four asynchronous endpoint buffers per translator, enabling concurrent high-bandwidth transfers across both downstream ports without bandwidth contention. Its upstream port negotiates USB 2.0 high-speed capability dynamically, disabling downstream high-speed operation when upstream is limited to full-/low-speed only.
Power management is configurable via hardware strapping (GANGED, FULLPWRMGMTz, PWRCTL_POL) or register control, supporting active-high/active-low power-enable polarity and individual or ganged overcurrent reporting. Battery charging modes-CDP, DCP (YD/T 1591-2009 compliant), and AutoMode with divider-mode fallback-are determined at reset by BATEN pins, VBUS status, and REG_Ah(autoModeEnz) state.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| USB Speed Support | Upstream: High-speed (480 Mbps); Downstream: High-speed/full-speed/low-speed - enables backward-compatible peripheral attachment with dynamic speed negotiation. |
| Supply Voltages | VDD = 0.99–1.26 V (1.1V rail); VDD33 = 3.0–3.6 V - dual-rail operation requiring separate low-noise LDOs for core and I/O domains. |
| Operating Temperature | –40°C to +85°C - qualified for industrial environments without derating, validated by junction temp limit of 105°C. |
| Package | 48-pin HTQFP (PHP), 9 mm × 9 mm - surface-mount package with exposed thermal pad for PCB-level heat dissipation. |
| ESD Rating | HBM ±4000 V, CDM ±1500 V - robust handling in manufacturing and end-equipment integration without additional protection circuitry. |
| Current Consumption | Active mode: 60 mA @ VDD33 / 80 mA @ VDD; Suspend: 5 mA / 39 mA - enables low-power system states while maintaining USB enumeration readiness. |
| Configuration Interface | OTP ROM, I²C EEPROM (100 kbps), or SMBus target - supports field-programmable VID/PID, port removability, battery charging mode, and UUID provisioning. |
Pinout & Package
Package: 48-pin HTQFP (PHP), 9 mm × 9 mm, with exposed thermal pad for thermal management. Industrial-grade variant rated for –40°C to +85°C ambient operation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| GRSTz (11) | Global Reset Input | Active-low synchronous reset; asserts internal register default state and disables all USB transceivers until deasserted after stable VDD/VDD33. |
| USB_DP_UP / USB_DM_UP (26,27) | Upstream Differential Pair | High-speed USB 2.0 interface to host controller; requires 90 Ω differential impedance routing and ESD protection. |
| USB_DP_DN1 / USB_DM_DN1 (41,42) USB_DP_DN2 / USB_DM_DN2 (14,15) |
Downstream Differential Pairs | Two independent USB 2.0 ports; each supports high/full/low-speed with integrated termination and slew-rate control. |
| PWRCTL1/BATEN1 (4) PWRCTL2/BATEN2 (6) |
Port Power/Battery Enable | Configures per-port power switching and battery charging mode (CDP/DCP) at reset; sampled synchronously with GRSTz deassertion. |
| OVERCUR1z (5) OVERCUR2z (8) |
Overcurrent Detection Inputs | Active-low signals from external power switches; in ganged mode, either pin reports hub-level overcurrent event. |
| SCL/SMBCLK (2) SDA/SMBDAT (3) |
I²C/SMBus Interface | Selectable via SMBUSz pin: I²C EEPROM bootloading (address 0x50) or SMBus target operation (address 0x88–0x8F). |
| GANGED/SMBA2/HS_UP (35) FULLPWRMGMTz/SMBA1 (36) |
Strap Configuration Inputs | Determine power control mode (individual/ganged), full power management enable, and SMBus address bits at reset. |
| VDD (1,12,18,30,34,45) VDD33 (7,13,23,25,33,37,40,48) |
Power Rails | Separate 1.1V core and 3.3V I/O supplies; decoupling required per TI layout guidelines to meet noise immunity specs. |

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 | Four-port MTT hub; requires external 24 MHz oscillator; no native DCP/YD/T 1591-2009 compliance; supports USB 2.0 Link Power Management (LPM). | Higher port count and LPM support suit multi-peripheral embedded systems; lacks integrated AutoMode charging logic and industrial temp grade. | Select USB2514B-AEZG when scaling beyond two downstream ports or requiring LPM for ultra-low-power sleep states. |
| TUSB2036VFR | Three-port STT (Single Transaction Translator) hub; single 3.3V supply; no battery charging support; smaller 32-pin QFN package. | Lower cost and footprint for basic expansion where charging and MTT performance are not required; incompatible with CDP/DCP use cases. | Choose TUSB2036VFR for cost-sensitive consumer docks or peripherals where only basic USB 2.0 fanout is needed. |
Compared with USB2514B-AEZG and TUSB2036VFR, the TUSB4020BIPHPR uniquely combines dual-port MTT performance, YD/T 1591-2009-compliant DCP, AutoMode charging, and industrial temperature rating in a single 48-pin HTQFP package - making it optimal for compact, feature-rich, thermally demanding USB-C accessory designs.

FAQ
What USB speed modes does the TUSB4020BIPHPR support on its downstream ports?
The TUSB4020BIPHPR supports high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) USB 2.0 operation on both downstream ports. Upstream port speed determines downstream capability: high-speed upstream enables high-speed downstream; full-/low-speed upstream disables high-speed downstream. This behavior is automatic and requires no software configuration in the TUSB4020BIPHPR.
Does the TUSB4020BIPHPR support battery charging, and which standards are implemented?
Yes, the TUSB4020BIPHPR supports battery charging via three modes: Charging Downstream Port (CDP) per USB Battery Charging Specification 1.2, Dedicated Charging Port (DCP) compliant with Chinese standard YD/T 1591-2009, and AutoMode that dynamically selects between DCP and divider-mode based on attached device. All modes are configured at reset via BATEN pins and registers, and no host driver is required for charging handshaking.
How is the TUSB4020BIPHPR configured - via hardware strapping, OTP, or external memory?
The TUSB4020BIPHPR supports multiple configuration methods: hardware strapping (GANGED, FULLPWRMGMTz, SMBUSz, PWRCTL_POL), one-time programmable (OTP) ROM for VID/PID and port settings, and external I²C EEPROM or SMBus target interface for full register customization including manufacturer strings and serial numbers. Configuration is sampled at GRSTz deassertion, and I²C/SMBus loading occurs before upstream enumeration.
What is the thermal performance of the TUSB4020BIPHPR in its 48-pin HTQFP package?
The TUSB4020BIPHPR in the PHP (HTQFP-48) package has a junction-to-ambient thermal resistance (RθJA) of 31.8°C/W, junction-to-board (RθJB) of 13°C/W, and junction-to-case (bottom) of 0.9°C/W. These values assume proper PCB layout with thermal vias under the exposed pad. The device is rated for continuous operation up to +85°C ambient with junction temperature maintained ≤105°C under typical active load conditions.
Can the TUSB4020BIPHPR operate without an external crystal, and what clock options are supported?
Yes, the TUSB4020BIPHPR supports both a 24 MHz crystal (connected between XI and XO pins) and a 24 MHz external oscillator (driving XI only, with XO left unconnected). The internal oscillator is fully integrated; no external components beyond the crystal or oscillator are required. Clock stability and jitter performance meet USB 2.0 specification requirements for both options, and layout guidelines emphasize short, shielded XI/XO traces away from noisy signals.
