TUSB4020BIPHPG4

Controllers Overview

The TUSB4020BIPHPG4 is a two-port USB 2.0 hub controller manufactured by Texas Instruments, housed in a 48-pin HTQFP package. It supports high-speed (480 Mbps), full-speed (12 Mbps), and low-speed (1.5 Mbps) data rates on downstream ports. The device operates with a 1.1V core supply (0.99V to 1.26V) and a 3.3V I/O supply (3.0V to 3.6V). It features an industrial operating temperature range of -40°C to 85°C and a maximum junction temperature of 105°C. Key electrical characteristics include a typical power-on current of 5mA at VDD33 and 39mA at VDD.

Controllers Feature Summary

• Supports battery charging modes including CDP and DCP compliant with YD/T 1591-2009
• Configurable via OTP ROM, I2C EEPROM, or SMBus target interface for custom VID/PID and strings
• Provides per-port or ganged power switching with overcurrent notification inputs
• Includes Multi-Transaction Translator (MTT) with four asynchronous endpoint buffers per translator

Controllers Applications

• Computer systems
• Docking stations
• Monitors
• Set-top boxes

Controllers Procurement Notes

Verify the G4 suffix indicates lead-free compliance and RoHS status as per Texas Instruments documentation. Confirm the specific package variant matches the 48-pin HTQFP requirement. Ensure the component source provides valid traceability for the active production status. Check datasheet revisions for any updates to thermal or electrical specifications before finalizing procurement.

Controllers Selection Notes

Select this component when a dual-port USB 2.0 hub solution with integrated battery charging support is required. Consider the 48-pin HTQFP package constraints for PCB layout. Evaluate the need for external configuration memory if custom VID, PID, or serial numbers are necessary. Verify that the system clock requirements align with the single 24MHz crystal input specification.

Controllers Part Context

The TUSB4020BIPHPG4 belongs to the TUSB4020BI family of USB 2.0 hubs from Texas Instruments. This series includes variants such as TUSB4020BIPHPR for reel packaging and automotive-grade versions like TUSB4020BI-Q1. The PHP designation specifically identifies the 48-pin High-Performance Thin Quad Flatpack package used in this model.

Controllers Replacement Considerations

Direct substitutes within the same family include TUSB4020BIPHPR, which shares identical electrical and functional specifications but utilizes reel packaging instead of tape-and-reel.
