TPS2069DGNG4

Power Distribution Switches, Load Drivers Overview

The TPS2069DGNG4 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 delivers an output current of 1.5 A. The device features a maximum on-resistance of 115 mΩ and a fixed current limit of 2.1 A. Key timing specifications include a maximum turn-on time of 3 ms and a maximum turn-off time of 10 ms. It is housed in an 8-MSOP-PowerPAD package with surface-mount installation. The component supports operation across a temperature range from -40°C to +85°C.

Power Distribution Switches, Load Drivers Feature Summary

• Integrates fixed current limiting protection to safeguard downstream loads against overcurrent conditions.
• Includes reverse current blocking capability to prevent backflow from the load side.
• Features undervoltage lockout (UVLO) to ensure stable operation during low supply voltages.
• Provides thermal shutdown protection to maintain device integrity under excessive heat.

Power Distribution Switches, Load Drivers Applications

• USB hub power distribution circuits
• Peripheral port power switching
• Hot-swap applications requiring controlled turn-on times

Power Distribution Switches, Load Drivers Procurement Notes

Verify the complete part number including the suffix G4, which indicates RoHS compliance and green packaging status. Confirm that the MSOP-PowerPAD-8 package matches the target PCB footprint and thermal pad requirements. Ensure the operating voltage range aligns with the system's 2.7 V to 5.5 V specification. Check for any specific tape-and-reel or tube packaging preferences if applicable to the assembly line.

Power Distribution Switches, Load Drivers Selection Notes

Select this component when a single-channel solution with moderate current capacity is required. The 1.5 A output current suits standard USB peripheral loads. Consider the 115 mΩ on-resistance for efficiency calculations. The 3 ms turn-on time helps mitigate inrush currents compared to faster switches. Verify that the 2.1 A current limit provides adequate headroom for the intended load without nuisance tripping.

Power Distribution Switches, Load Drivers Part Context

This device belongs to the TPS20xx family of USB power switches designed for power distribution applications. It shares functional similarities with other members like the TPS2061 and TPS2065 but differs in channel count and current ratings. The DGNG4 variant specifically denotes the MSOP-PowerPAD package configuration.
