TPS2111APWR

OR Controllers, Ideal Diodes Overview

The TPS2111APWR is a dual-input single-output power multiplexer from Texas Instruments designed for seamless switching between two power sources, such as a battery and an AC adapter. It operates within a voltage range of 2.8 V to 5.5 V and supports a maximum output current of 750 mA. The device features a typical on-resistance of 84 mΩ and includes user-programmable current limiting adjustable from 310 mA to 750 mA. It provides protection against reverse conduction, cross-conduction, and thermal overload, with a controlled turn-on time of up to 500 µs to manage inrush current.

OR Controllers, Ideal Diodes Feature Summary

OR Controllers, Ideal Diodes Procurement Notes

Verify the package suffix 'PWR' corresponds to the TSSOP-8 tape and reel configuration. Confirm RoHS compliance status matches the specific manufacturing lot requirements. Ensure the operating temperature range aligns with the -40°C to +85°C specification. Cross-reference the datasheet revision date to ensure compatibility with design constraints.

OR Controllers, Ideal Diodes Selection Notes

Select this component when a low-profile solution is required for portable electronics needing dual-source redundancy. The 84 mΩ on-resistance offers lower power dissipation compared to standard diode ORing solutions. The programmable current limit allows adaptation to various load profiles without changing internal components. Consider the TSSOP-8 footprint for space-constrained PCB layouts.

OR Controllers, Ideal Diodes Part Context

This part belongs to the TPS211xA series of power multiplexers. It shares architectural similarities with the TPS2110A but differs in on-resistance characteristics. The series is engineered for applications requiring high reliability and minimal voltage drop during power transitions. It complements other TI power management ICs by providing input selection logic.

OR Controllers, Ideal Diodes Replacement Considerations

The TPS2110A is a functional substitute within the same family, offering similar switching capabilities but with a higher typical on-resistance of 120 mΩ. Verify that the increased resistance does not exceed thermal limits in the target application. Both parts share identical pinouts and control logic.
