TPS2115ADRBR

Overview

The TPS2115ADRBR is an OR controller and source selector switch manufactured by Texas Instruments. It features a 2:1 input-to-output ratio with internal N-channel FETs housed in an 8-SON (3x3) package. The device supports a supply voltage range of 2.8V to 5.5V and delivers a maximum output current of 2A. Key timing parameters include a turn-on delay of 1 ms and a turn-off delay of 5 ms. It operates within a temperature range of -40°C to 85°C and consumes 55 µA of supply current.

Feature Summary

• Integrates dual N-channel FETs for seamless power path selection between two sources.
• Provides automatic source selection logic to maintain continuous power delivery.
• Features low quiescent current consumption for efficient battery-powered operation.

Applications

• Handheld mobile devices
• Portable consumer electronics
• Battery backup systems

Procurement Notes

Verify the specific suffix ADRBR corresponds to the 8-SON package and tape-and-reel packaging configuration. Confirm RoHS compliance status and moisture sensitivity level requirements against project specifications. Ensure the ordering number matches the exact pinout and thermal pad design required for the PCB layout.

Selection Notes

Select this component when designing circuits requiring automatic switchover between two power rails with minimal interruption. Consider the 2A current limit and 110 mΩ on-resistance characteristics for load requirements. Evaluate the 1 ms turn-on time against system startup constraints and verify compatibility with the available input voltage ranges.

Part Context

This part belongs to the TPS2115A series of power multiplexers and OR controllers. It is functionally related to the TPS2113A, which offers similar architecture but with a lower 1.25A current rating. The series is designed for compact portable applications where space efficiency and reliable power management are critical priorities.

Replacement Considerations

TPS2113ADRBR serves as a verified substitute within the same family, though it has a reduced 1.25A output current rating compared to the 2A capability of the TPS2115ADRBR. Ensure the application load does not exceed the lower threshold of the replacement part.
