TPS25821DSSR

Specialized Overview

The TPS25821DSSR is a USB Type-C source controller and power switch manufactured by Texas Instruments. It operates within a supply voltage range of 4.5 V to 5.5 V and supports a continuous output current of 1.5 A. The device complies with the USB Type-C 2.0 standard and features a Downstream Facing Port (DFP) interface. It is housed in a 12-pin WSON package with dimensions of 3 mm. The component functions reliably across an extended temperature range from -40 °C to +125 °C.

Specialized Feature Summary

• Integrates CC pin monitoring for automatic VBUS management
• Provides overcurrent protection to safeguard downstream DC-DC converters
• Supports USB Type-C 2.0 specification compliance

Specialized Applications

• Designing single-source USB Type-C ports
• Systems requiring approximately 1A output at 5V VBUS
• Portable electronic devices needing integrated power switching

Specialized Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer, as these details are subject to change and vary by region.

Specialized Selection Notes

Select this component when designing a dedicated source port that requires integrated CC line monitoring rather than external microcontroller management. Compare against alternatives like the TPS2553 if precise current limiting without CC integration is preferred. Ensure the 1.5 A rating meets the system's peak load requirements.

Specialized Part Context

This part belongs to the TPS2582x series of USB Type-C controllers. It shares the same 12-pin WSON package and operational characteristics with other variants in the family, differentiated primarily by internal configuration or specific electrical thresholds defined in the technical documentation.

Specialized Replacement Considerations

The TPS25820DSST is a related variant within the same product family. Verify functional equivalence regarding USB Type-C version support and current handling capabilities before substitution.
