TPS2105DBVT

Overview

The TPS2105DBVT is a dual-input single-output power multiplexer IC manufactured by Texas Instruments. It operates within a supply voltage range of 2.7 V to 5.5 V and supports an output current of 500 mA. The device features a maximum on-resistance of 2.4 Ohms, with a maximum turn-on time of 340 us and a maximum turn-off time of 6 us. It is housed in a SOT-23-5 surface-mount package and functions across a temperature range of -40°C to +85°C.

Feature Summary

Integrates N-channel and P-channel MOSFETs for bidirectional source selection
Provides low on-resistance for efficient power distribution
Features fast switching times for rapid input transitions

Applications

Handheld devices requiring multiple power sources
Mobile equipment needing seamless power path management
Battery-powered systems utilizing redundant power inputs

Procurement Notes

Verify the specific suffix 'VT' against the manufacturer's official datasheet to confirm the tape-and-reel packaging configuration and quantity. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the ordering information with the latest Texas Instruments documentation to avoid discrepancies in package type or marking codes.

Selection Notes

Select this component when a compact solution for dual-input power routing is required. The SOT-23-5 package offers space efficiency for portable designs. Consider the 500 mA output limit and 2.4 Ohm resistance for thermal and voltage drop calculations. Verify that the 2.7 V minimum operating voltage aligns with the system's power rail specifications.

Part Context

This part belongs to the TPS2105 series of OR controllers and source selector switches. It serves as a power distribution switch for managing two input sources into a single output. The device is designed for applications requiring automatic switchover between power sources without interruption.
