TPS2113PWRG4

Overview

The TPS2113PWRG4 is an autoswitching power multiplexer manufactured by Texas Instruments, designed for seamless source selection in portable electronics. It operates within a supply voltage range of 2.8 V to 5.5 V and supports a maximum output current of 1.25 A. The device features a low on-resistance of 110 mΩ and includes configurable delay times with a maximum turn-on time of 1 ms and turn-off time of 5 ms. It is housed in an 8-TSSOP package and functions reliably across an operating temperature range of -40 °C to +85 °C.

Feature Summary

• Autoswitching capability ensures continuous power delivery by automatically selecting the optimal input source without interruption.
• Low on-resistance minimizes power loss and heat generation during conduction.
• Configurable delay times allow customization of switching behavior to prevent glitches or meet specific system timing requirements.

Applications

• Portable handheld devices requiring redundant power sources
• Battery-powered equipment needing seamless transition between AC adapter and battery
• Mobile communication systems utilizing multiple power rails

Procurement Notes

Verify the G4 suffix indicates lead-free compliance and RoHS conformity as per Texas Instruments standards. Confirm the TSSOP-8 package dimensions match your PCB footprint design. Ensure the operating temperature range aligns with your environmental specifications. Cross-reference the datasheet revision to confirm electrical characteristics remain unchanged from previous versions.

Selection Notes

Select this component when a single-channel power mux with autoswitching functionality is required. It is suitable for applications needing low standby current and high efficiency. Consider the 1.25 A current limit and 110 mΩ resistance against load requirements. Evaluate the 2.8 V to 5.5 V input range compatibility with available power sources.

Part Context

The TPS2113PWRG4 belongs to the TPS211x series of power multiplexers from Texas Instruments. This family provides integrated solutions for managing multiple power inputs in space-constrained designs. The device integrates control logic and N-channel switches into a compact package, simplifying board layout compared to discrete implementations.

Replacement Considerations

Publicly confirmed substitutes include TPS2113PW and TPS2113APWR. Verify pinout compatibility and electrical parameters before substitution. The TPS2110A may serve as a functional alternative if lower current ratings are acceptable.
