TPS2110PWRG4

Overview

The TPS2110PWRG4 is an autoswitching power multiplexer manufactured by Texas Instruments, designed to manage power selection between two input sources. It operates within an input voltage range of 2.8V to 5.5V and supports a maximum output current of 0.75A per channel. The device features a typical on-resistance (rDS(on)) of 120mΩ for both inputs. It is housed in an 8-pin TSSOP package and functions reliably across an operating temperature range of -40°C to +85°C.

Feature Summary

• Autoswitching capability allows seamless transition between two power sources without manual intervention
• Integrated low on-resistance switches minimize power loss during conduction
• Compact surface-mount packaging facilitates integration into space-constrained designs

Applications

• Portable electronic devices requiring dual power source management
• Battery backup systems with primary power switching
• Embedded systems needing redundant power input handling

Procurement Notes

Verify the specific suffix 'G4' indicates lead-free compliance and RoHS status as per Texas Instruments documentation. Confirm the package type matches the required PCB footprint. Ensure the operating environment stays within the specified -40°C to +85°C range. Cross-reference the datasheet for exact pinout configurations before finalizing procurement.

Selection Notes

Select this component when a low-cost, single-slot power mux is needed for inputs up to 5.5V. Consider the 120mΩ on-resistance impact on efficiency. Evaluate if the 0.75A current limit meets load requirements. Compare against TPS2111A if higher current or lower resistance is necessary.

Part Context

This part belongs to the TPS211x family of autoswitching power multiplexers from Texas Instruments. These devices are engineered for applications requiring automatic power source selection. The TPS2110 variant specifically targets lower current applications compared to other members like the TPS2111.

Replacement Considerations

TPS2111A is a documented alternative within the same family, offering different electrical characteristics such as lower on-resistance and higher current capacity.
