TPS2113APWR

Overview

The TPS2113APWR is a power multiplexer manufactured by Texas Instruments, designed for automatic switching between two input sources to a single output. It operates within a supply voltage range of 2.8V to 5.5V and supports an output current of up to 1.25A. The device features a typical on-resistance of 84mΩ and consumes 55μA of quiescent current. It is housed in an 8-pin TSSOP package with dimensions of 3.00 x 4.40mm and a height of 1.20mm. The component functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

• Automatically selects the active input source based on voltage levels without external control logic
• Provides status output indication for monitoring the selected power path
• Integrates low on-resistance N-channel switches for efficient power distribution

Applications

• Handheld and mobile devices requiring seamless power source transitions
• Systems utilizing dual battery configurations for extended operation
• Portable electronics needing redundant power supply management

Procurement Notes

Verify that the part number suffix 'PWR' corresponds to the TSSOP-8 package configuration as specified in the manufacturer datasheet. Confirm RoHS compliance status through official documentation before integration. Ensure the operating environment remains within the specified -40°C to +85°C temperature range for reliable performance. Cross-reference the specific revision level with the latest product data sheet to avoid discrepancies.

Selection Notes

Select this component when automatic source selection is required for dual-input power architectures. It is suitable for applications demanding low insertion loss and minimal standby current consumption. Consider the 1.25A output capability against the load requirements. Evaluate the TSSOP-8 footprint constraints against the PCB layout availability. This device is appropriate where manual switching or complex control logic is undesirable.

Part Context

The TPS2113A series belongs to Texas Instruments' portfolio of power multiplexers and load switches. These components are engineered to manage power routing in portable systems. The TPS2113 variant specifically offers higher current capacity compared to lower-rated siblings like the TPS2112. The family focuses on simplifying power design by automating source selection and providing status feedback.

Replacement Considerations

TPS2113PW serves as a package-compatible alternative within the same series.
