TPS2069DGNR

Power Distribution Switches, Load Drivers Overview

The TPS2069DGNR is a single-channel USB power distribution switch manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an output current of 1.5 A with a typical current limit of 2.1 A. The device features a maximum on-resistance of 115 mOhms, ensuring efficient power delivery. Key timing parameters include a maximum turn-on time of 3 ms and a maximum turn-off time of 10 ms. It is designed for surface-mount installation in an MSOP-PowerPad-8 package and functions reliably across an operating temperature range from -40°C to +85°C.

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging configuration when sourcing. Confirm that the DGN package variant matches the required PCB footprint and thermal pad requirements. Ensure the component meets RoHS compliance standards applicable to your manufacturing region. Cross-reference the datasheet revision date to confirm parameter consistency with your design specifications.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a wide input voltage range starting at 2.7 V is required compared to higher-voltage-only alternatives. The 1.5 A continuous output rating suits standard USB peripheral loads. Consider the MSOP-PowerPad-8 package for space-constrained designs requiring effective thermal dissipation through the exposed pad.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the TPS2069 family of USB power switches, which also includes variants like the TPS2069CDGN. While sharing similar functionality, the DGN variant offers a wider operating voltage range (2.7 V–5.5 V) compared to the CDGN variant (4.5 V–5.5 V). The family provides integrated protection features essential for modern USB power distribution architectures.

Power Distribution Switches, Load Drivers Replacement Considerations

The TPS2069CDGN serves as a related variant but operates only between 4.5 V and 5.5 V. Verify if the lower minimum voltage of the CDGN is sufficient for the application. Other TPS206x series members may offer different current ratings or package options.
