Overview
The TSU6721YFPR is a dual-channel USB switch IC manufactured by Texas Instruments, designed for portable applications. It integrates SP3T switches to manage audio, UART, and USB connections. The device operates on a single supply voltage ranging from 4V to 6.5V. It features integrated charger detection and ID bypass capabilities, supporting USB 2.0 standards. Control is achieved via I2C or UART interfaces. The component is housed in a compact 25-DSBGA package and supports surface mount installation. It functions within an ambient temperature range of -40°C to 85°C.
Feature Summary
- Integrates dual SP3T switches for routing audio, UART, and USB signals in portable devices.
- Includes built-in charger detection and ID bypass switch functionality for power management.
- Supports digital control through standard I2C and UART communication protocols.
- Compatible with USB 2.0 specifications for data and peripheral connectivity.
Applications
- Portable electronic devices requiring USB port sharing
- Audio signal routing in mobile systems
- UART interface switching for embedded controllers
Procurement Notes
Verify the specific suffix YFPR against the manufacturer datasheet to confirm the tape and reel packaging configuration. Ensure the order quantity aligns with the standard manufacturing pack size to avoid partial reel handling issues. Confirm RoHS3 compliance status if environmental regulations apply to the target assembly process.
Selection Notes
Select this component when a dual-channel solution is required for managing multiple peripheral connections in space-constrained designs. Verify that the system supply voltage falls within the 4V to 6.5V operating range. Consider the 25-DSBGA footprint during PCB layout planning to ensure adequate thermal dissipation and mechanical stability for the surface mount application.
Part Context
This part belongs to the TSU6721 family of USB switches from Texas Instruments. It serves as a specialized interface solution for managing connectivity in mobile hardware. The device complements other power management and interface components by providing dedicated signal routing capabilities without requiring external multiplexers.
Replacement Considerations
Consult the official Texas Instruments documentation for verified cross-reference part numbers. Do not assume functional equivalence with generic SPDT or SP3T switches lacking integrated charger detection or ID bypass features. Validate pin compatibility and control logic before substituting.
