TPS2110APW

Overview

The TPS2110APW is an autoswitching power multiplexer from Texas Instruments designed for dual-input, single-output applications. It operates within a voltage range of 2.8 V to 5.5 V and supports a maximum output current of 0.75 A. The device features a typical on-resistance (rDS(on)) of 120 mΩ. It includes user-programmable current limiting, thermal shutdown, and surge current control. The component is housed in an 8-pin TSSOP package and functions across an operating temperature range of -40°C to +85°C.

Feature Summary

• Enables seamless switching between two power sources such as batteries and wall adapters
• Provides reverse conduction and cross-conduction blocking protection
• Supports both manual and automatic switching modes via control inputs
• Includes adjustable current limiting and thermal shutdown capabilities

Applications

• Personal computers
• Portable digital cameras
• Mobile phones
• Modems
• MP3 players

Procurement Notes

Verify the specific suffix 'PW' confirms the TSSOP-8 package variant. Confirm the 'A' designation aligns with the standard catalog rating. Ensure the datasheet matches the required 120 mΩ on-resistance specification. Check RoHS compliance status if environmental regulations apply. Validate the operating temperature range against system requirements.

Selection Notes

Select this component when a low-profile 8-pin surface-mount solution is required for portable electronics. Choose the TPS2110APW for applications needing 0.75 A continuous current capability. Consider the 120 mΩ on-resistance for efficiency calculations. Verify that the 2.8 V to 5.5 V input range matches available power rails. Evaluate the need for programmable current limiting features.

Part Context

This part belongs to the TPS211xA series of power multiplexers. It shares functional similarities with the TPS2111A but differs in on-resistance and current ratings. The series is designed for battery-powered devices requiring redundant power sources. It integrates protection circuits to simplify system design compared to discrete solutions.

Replacement Considerations

The TPS2111A is a documented alternative within the same family. Note that the TPS2111A offers lower on-resistance and higher current capacity. Verify pin compatibility and electrical specifications before substitution.
