TPS2104D

Overview

The TPS2104D is a power multiplexer IC from Texas Instruments featuring dual inputs and a single output. It utilizes an internal N-channel MOSFET with a maximum on-resistance of 2.4 ohms to manage power distribution. The device supports a supply voltage range of 2.7 V to 5.5 V and delivers a continuous output current of 500 mA. Key timing specifications include a maximum turn-on time of 340 µs and a maximum turn-off time of 6 µs. It operates within a temperature range of -40°C to +85°C and is available in surface-mount packages such as SOT-23-5.

Feature Summary

Dual input selection for flexible power source management
Integrated N-channel MOSFET for low-loss power switching
Built-in protection against reverse current flow

Applications

Portable electronic devices requiring redundant power sources
Battery-backed systems for seamless power transitions
Power distribution networks in consumer electronics

Procurement Notes

Verify the specific suffix (e.g., DBVT, DBVR) to confirm package type and reel configuration. Ensure the selected variant matches the required thermal performance and PCB footprint. Cross-reference the datasheet for exact pinout compatibility and electrical limits before integration into the design.

Selection Notes

Select this component when a compact solution for dual-input power switching is required. Consider the 2.4-ohm on-resistance for voltage drop calculations under full load. Verify that the 500 mA current rating meets the system's peak demand requirements and that the operating voltage aligns with the available power rails.

Part Context

The TPS2104 belongs to a family of power mux ICs designed for efficient power routing. It serves as a critical interface between multiple power sources and the load, ensuring uninterrupted operation. The series offers various package options to suit different space constraints and thermal management needs in portable applications.
