TPS2105MDBVREP

Overview

The TPS2105MDBVREP is an OR controller and source selector switch manufactured by Texas Instruments. It supports N-channel and P-channel FETs in a 2:1 input-to-output configuration. The device operates within a supply voltage range of 2.7 V to 5.5 V and functions reliably across temperatures from -55°C to 125°C. Key electrical specifications include a maximum output current of 500 mA, with individual inputs rated at 100 mA each. The unit consumes 18 µA of supply current and is housed in a SOT-23-5 package.

Feature Summary

• Integrates control logic for both N-channel and P-channel field-effect transistors
• Provides automatic source selection between two power inputs
• Supports high-temperature operation up to 125°C

Applications

• Handheld devices
• Mobile equipment
• Systems requiring redundant power sources

Procurement Notes

Verify the specific suffix MDBVREP against official Texas Instruments documentation to confirm the exact tape-and-reel quantity and packaging format. Ensure the component meets RoHS3 compliance requirements for your assembly process. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when designing circuits that require seamless power path management using discrete MOSFETs. It is suitable for applications needing dual-input redundancy with low quiescent current consumption. Consider the SOT-23-5 footprint constraints and the thermal performance limits defined by the 125°C maximum junction temperature rating during layout planning.

Part Context

This part belongs to the TPS2105 series of power switches and OR controllers. It serves as a specialized integrated circuit for managing power distribution in portable electronics. The device simplifies the design of backup power systems by handling the switching logic externally connected to N or P channel FETs.
