TPS2113ADRBT

Overview

The TPS2113ADRBT is an autoswitching power multiplexer manufactured by Texas Instruments, designed for seamless source selection in portable electronics. It features a single output with a maximum continuous current of 1.25 A and an adjustable current limit ranging from 630 mA to 2 A. The device operates within a supply voltage range of 2.8 V to 5.5 V and exhibits a maximum on-resistance of 110 mOhms. It supports input-to-output ratios of 2:1 or 4:1, ensuring reliable power distribution. The component functions within a temperature range of -40°C to +85°C and is housed in an 8-SON (3x3 mm) package.

Feature Summary

• Autoswitching logic automatically selects the highest available voltage source without external control signals
• Integrated N-channel MOSFETs provide low on-resistance for efficient power delivery
• Configurable current limit allows protection against overcurrent conditions across various loads

Applications

• Battery backup systems in handheld devices
• Power path management in mobile phones
• Source selection in portable computing equipment

Procurement Notes

Verify the specific suffix 'RBT' against the official Texas Instruments datasheet to confirm tape-and-reel packaging specifications and quantity per reel. Ensure the order matches the exact 8-SON package dimensions and pinout configuration required by the design. Cross-reference the manufacturer part number with authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component when automatic source switching between two power inputs is required without microcontroller intervention. It is suitable for applications needing a compact solution for power path management. Consider the 1.25 A output capability and 110 mOhm resistance for efficiency requirements. Verify that the 2.8 V to 5.5 V operating range aligns with the system's power rails.

Part Context

The TPS2113A series belongs to Texas Instruments' family of autoswitching power multiplexers. These devices are engineered to simplify power distribution in battery-operated products by managing multiple input sources. The series offers integrated protection features and low profile packaging, making it a standard choice for modern portable electronic designs requiring robust power management.

Replacement Considerations

Check the TPS2113APWR for leaded TSSOP-8 alternatives if surface mount constraints differ. The TPS2113ADRBR is a compatible variant in the same SON package family. Verify pin compatibility and electrical parameters before substituting.
