TPS2114PWRG4

Overview

The TPS2114PWRG4 is a source selector switch IC manufactured by Texas Instruments, designed for ORing controller applications. It operates within a supply voltage range of 2.8V to 5.5V and features an internal N-channel FET with a maximum output current of 750mA. The device supports a 2:1 input-to-output ratio and includes built-in delay mechanisms, specifically a 500µs turn-on delay and a 3ms turn-off delay. It is housed in an 8-TSSOP package (0.173" width) and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Integrates an internal N-channel FET for efficient power path management
• Provides configurable turn-on and turn-off delays to control switching timing
• Supports 2:1 source selection architecture for redundant power inputs

Applications

• Handheld devices requiring seamless power source transition
• Mobile equipment utilizing multiple battery or charger inputs
• Portable electronics needing low-power ORing solutions

Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's latest documentation to confirm RoHS compliance status and lead time availability. Ensure the TSSOP-8 footprint matches your PCB design constraints. Confirm that the 750mA current rating meets your system's peak load requirements without exceeding thermal limits.

Selection Notes

Select this component when a fixed 2:1 source selection topology is required for portable systems. It is suitable for applications where precise turn-on/off sequencing is necessary to prevent backflow or inrush issues. Consider the 8-TSSOP package size if board space is limited compared to larger QFN options.

Part Context

This part belongs to the TPS2114/TPS2115 family of OR controllers and source selector switches from Texas Instruments. These devices are engineered to manage power distribution between two sources, such as a battery and an adapter, ensuring continuous operation during source transitions in mobile and handheld form factors.

Replacement Considerations

The TPS2115APWRG4 is a documented variant within the same family offering similar functionality but potentially different current ratings or delay characteristics. Verify pin compatibility and electrical specifications before substitution.
