TPS2114APWR

Overview

The TPS2114APWR is a source selector switch manufactured by Texas Instruments, designed for power distribution applications. It features an N-channel internal switch with a 2:1 input-to-output ratio and is housed in an 8-TSSOP package. The device operates within a supply voltage range of 2.8 V to 5.5 V and supports a maximum output current of 750 mA. Key timing parameters include a maximum turn-on delay of 500 µs and a maximum turn-off delay of 3 ms. It functions as an OR controller, ensuring reliable power selection between two sources.

Feature Summary

• Integrates an N-channel internal switch for efficient power routing
• Automatically selects the highest available voltage source from two inputs
• Provides controlled turn-on and turn-off delays to manage inrush current

Applications

• Handheld devices requiring dual-source power management
• Mobile equipment needing seamless power switching
• Battery-backed systems utilizing primary and secondary power rails

Procurement Notes

Verify that the specific part number matches the required 8-TSSOP package configuration and ensure compatibility with the target system's voltage levels. Confirm RoHS compliance status through official documentation before finalizing procurement orders. Cross-reference the manufacturer's latest datasheet to validate electrical characteristics against design specifications.

Selection Notes

Select this component when a compact solution for automatic power source selection is required. Ensure the application voltage remains within the 2.8 V to 5.5 V operating range. Consider the 750 mA output current limit and thermal dissipation capabilities in the 8-TSSOP package. Verify that the 500 µs turn-on delay aligns with system startup requirements.
