TPS2113PWG4

Overview

The TPS2113PWG4 is an autoswitching power multiplexer manufactured by Texas Instruments. It functions as a source selector switch with two inputs and one output, utilizing internal N-channel FETs. The device supports input voltages from 2.8V to 5.5V and delivers a maximum output current of 1.25A. Key electrical parameters include a typical on-resistance of 84 milliohms, a supply current of 55 microamperes, a turn-on delay of 1 millisecond, and a turn-off delay of 5 milliseconds. It operates within a temperature range of -40°C to 85°C and is housed in an 8-TSSOP package.

Feature Summary

• Autoswitching logic automatically selects the optimal power source based on voltage levels without external control signals.
• Integrated N-channel field-effect transistors provide low on-resistance for efficient power distribution.
• Low quiescent supply current minimizes power consumption during standby or idle states.
• Compact surface-mount packaging facilitates integration into space-constrained portable electronic designs.

Applications

• Handheld mobile devices requiring seamless battery-to-adapter switching
• Portable electronics needing redundant power source management
• Systems requiring automatic selection between primary and backup power supplies

Procurement Notes

Verify that the specific ordering suffix matches the required tape-and-reel or tube packaging configuration. Confirm RoHS compliance status aligns with project environmental regulations. Ensure the component rating meets the thermal and electrical requirements of the target application environment before finalizing procurement orders.

Selection Notes

Select this component when an autoswitching function is required for dual-input power paths. Compare against the TPS2112A if lower current capacity is acceptable, or consider the TPS2113APWR for reel packaging options. Verify that the 1.25A output current limit satisfies the load requirements of the downstream circuitry.

Part Context

This part belongs to the TPS211x family of autoswitching power muxes from Texas Instruments. It serves as a power management integrated circuit designed to manage multiple power sources. The G4 suffix indicates lead-free manufacturing compliant with specific environmental standards, distinguishing it from earlier non-compliant variants within the same functional series.

Replacement Considerations

The TPS2113PW is a direct functional equivalent. The TPS2113APWR offers identical electrical performance but utilizes a different packaging format. Cross-reference pinouts and thermal characteristics when substituting to ensure mechanical compatibility.
