TPS2068CDGN

Power Distribution Switches, Load Drivers Overview

The TPS2068CDGN is a single-channel, current-limited USB power distribution 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 features a maximum on-resistance of 98 mΩ and a current limit of 2.9 A. It includes programmable rise and fall times with maximum values of 2.2 ms and 2.5 ms, respectively. The component is housed in an MSOP-PowerPad-8 package and is rated for operation between -40°C and +85°C.

Power Distribution Switches, Load Drivers Feature Summary

• Provides precise current limiting to protect downstream USB loads from overcurrent conditions.
• Features programmable rise and fall times to control inrush current and reduce electromagnetic interference.
• Integrates thermal shutdown protection to safeguard the device during fault conditions.

Power Distribution Switches, Load Drivers Applications

• USB hub power distribution circuits
• Peripheral device power switching
• Portable electronics power management

Power Distribution Switches, Load Drivers Procurement Notes

Verify the specific suffix 'CDGN' to confirm the commercial temperature grade (-40°C to +85°C) and tube packaging format. Ensure the design accommodates the 4.5 V minimum operating voltage, as this variant differs from wider-voltage options like the TPS2068D series. Cross-reference the datasheet for exact pinout compatibility if substituting into existing layouts.

Power Distribution Switches, Load Drivers Selection Notes

Select this part when a single channel with strict 5 V USB compliance is required. The 98 mΩ on-resistance offers lower conduction loss compared to higher-resistance alternatives. Consider the TPS2068D series if a wider input voltage range starting at 2.7 V is necessary, or the TPS2069C if identical electrical characteristics are needed but different packaging or availability is preferred.

Power Distribution Switches, Load Drivers Part Context

This component belongs to the TPS206x family of USB power switches designed for portable applications. It complements other variants such as the dual-channel TPS2066 and the wider-voltage TPS2068D. The family shares common protection features while offering variations in channel count, voltage range, and package options to suit diverse system requirements.

Power Distribution Switches, Load Drivers Replacement Considerations

The TPS2068DGN serves as a direct functional substitute with a wider voltage range (2.7 V–5.5 V). The TPS2069CDGN offers identical electrical specifications and may be used interchangeably depending on inventory availability.
