TPS2114PWR

Overview

The TPS2114PWR is a power multiplexer from Texas Instruments designed for dual-input, single-output power distribution. It operates within a supply voltage range of 2.8 V to 5.5 V and supports an output current of 0.75 A. The device features a maximum on-resistance of 120 mΩ. It provides manual, automatic, and slow switchover capabilities along with a status output. The component functions reliably across a temperature range of -40°C to +85°C and is housed in an 8-pin TSSOP package.

Feature Summary

• Supports manual, automatic, and slow switchover modes for flexible power path management
• Integrates a status output pin for monitoring active input source selection
• Provides low on-resistance switching for efficient power distribution

Applications

• Portable computing devices requiring seamless battery-to-adapter switching
• Embedded systems needing redundant power input handling
• Consumer electronics utilizing multiple power sources

Procurement Notes

Verify the specific ordering suffix to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status through official documentation. Check for obsolete status or lifecycle notices as this part may be discontinued. Ensure the selected variant matches the required thermal and electrical ratings for the target application environment.

Selection Notes

Select this component when a dual-input power mux with 0.75 A capacity is required. Consider the 120 mΩ on-resistance for power loss calculations. Evaluate the need for automatic versus manual switching based on system control logic. Verify that the 2.8 V minimum operating voltage aligns with the lowest expected supply rail.

Part Context

This part belongs to the TPS2114 series of autoswitching power multiplexers. It is distinct from higher-current variants like the TPS2116. The PWR suffix indicates an 8-pin TSSOP package with tape-and-reel packaging. This series focuses on portable applications where space and efficiency are critical constraints.
