TPS2111APWRG4

Overview

The TPS2111APWRG4 is an autoswitching power multiplexer manufactured by Texas Instruments. It features a single input and one output, housed in an 8-TSSOP package. The device operates within a supply voltage range of 2.8V to 5.5V and supports an operating temperature range from -40°C to +85°C. It includes internal N-channel switches with a typical on-resistance of 120 milliohms per channel. The component is RoHS compliant and designed for source selection applications.

Feature Summary

• Autoswitching functionality enables automatic transition between power sources without external control logic
• Integrated N-channel power switches provide low on-resistance for efficient power delivery
• Compact surface-mount packaging facilitates integration into space-constrained portable designs

Applications

• Handheld and mobile devices requiring redundant power inputs
• Battery backup systems utilizing primary and secondary power sources
• Portable electronics needing seamless power source switching

Procurement Notes

Verify the specific suffix G4 indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm the TSSOP-8 package dimensions match your PCB footprint requirements. Ensure the operating voltage range aligns with your system's power rails. Check for any recent product level notifications or design changes that may affect long-term availability or specifications.

Selection Notes

Select this component when a single-input, single-output autoswitching solution is required. Consider the 120 milliohm on-resistance for power loss calculations. Evaluate the 8-TSSOP package size against available board space. Compare performance metrics against similar models like the TPS2112A if multiple inputs are needed. Verify thermal dissipation capabilities within the specified temperature range.

Part Context

This part belongs to the TPS211x family of autoswitching power muxes from Texas Instruments. These devices are designed for managing power sources in portable applications. The series offers various configurations including single and dual input options. They integrate protection features and low-loss switches to ensure reliable power path management in compact form factors.

Replacement Considerations

Public confirmed substitutes include TPS2111APW and TPS2111PWR. Verify pinout compatibility and electrical parameters before substitution. Ensure the replacement part meets the same RoHS and environmental standards.
