TPS2068DGNR

Power Distribution Switches, Load Drivers Overview

The TPS2068DGNR 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 a continuous output current of 1.5 A with a fixed current limit of 2.1 A. The device features a maximum on-resistance of 115 mOhms, ensuring efficient power delivery. It includes protection mechanisms such as thermal shutdown and under-voltage lockout. The component is housed in an 8-pin MSOP-PowerPad package suitable for surface mount applications and functions across an operating temperature range from -40°C to +85°C.

Power Distribution Switches, Load Drivers Feature Summary

• Portable electronic device power management
• Peripheral connection protection interfaces

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'DGNR' corresponds to the tape-and-reel packaging configuration required for automated assembly processes. Confirm that the MSOP-PowerPad-8 footprint matches the design layout, paying attention to the exposed pad thermal requirements. Ensure the selected variant meets the necessary RoHS compliance standards for the target market regulations.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a single-channel solution with a 1.5 A continuous current rating is sufficient for the load requirements. Consider the 115 mOhms on-resistance for efficiency calculations compared to lower-resistance alternatives. Evaluate the 2.7 V minimum operating voltage against the system's available rail to ensure reliable activation during low-power states.

Power Distribution Switches, Load Drivers Part Context

This part belongs to the TPS206x family of USB power switches designed for overcurrent protection. It serves as a discrete alternative to integrated hub controllers, allowing designers to manage individual port power independently. The device complements other variants like the TPS2066 and TPS2069 which offer different channel counts or current ratings within the same series.
