TPS2114PW

Overview

The TPS2114PW is a source selector switch manufactured by Texas Instruments, designed for power distribution applications. It features an N-channel internal switch with a 2:1 input-to-output ratio and supports a supply voltage range of 2.8V to 5.5V. The device delivers a maximum output current of 750mA and operates within a temperature range of -40°C to +85°C. Packaged in an 8-TSSOP surface-mount format, it includes specific timing characteristics such as a 500µs turn-on delay and a 3ms turn-off delay.

Feature Summary

• Functions as a source selector switch for managing multiple power inputs
• Integrates an N-channel internal switch for efficient power routing
• Supports dual-input selection with a defined 2:1 input-to-output ratio

Applications

• Power distribution in handheld devices
• Power distribution in mobile equipment
• Source selection circuits in portable electronics

Procurement Notes

Verify the component status carefully before procurement. Official records indicate that the TPS2114PWG4 variant has been discontinued by DigiKey, with the standard TPS2114PW listed as the available alternative. Confirm current availability directly with the manufacturer or authorized distributors, as stock levels may vary. Ensure the selected package matches the design requirements for the 8-TSSOP form factor.

Selection Notes

Select this component when designing systems requiring automatic source selection between two power rails. It is suitable for applications needing a compact solution with low quiescent current of 55µA. Consider the 750mA output limit and the specific turn-on/turn-off delays when evaluating system startup behavior. The 8-TSSOP package is appropriate for space-constrained printed circuit board layouts.

Part Context

This part belongs to the TPS211x series of OR controllers and source selector switches from Texas Instruments. These components are engineered to manage power sources in portable electronics, ensuring seamless transitions between primary and backup power supplies. The series typically integrates protection features and low-power operation modes suitable for battery-powered devices.

Replacement Considerations

TPS2114PW is identified as a substitute for the discontinued TPS2114PWG4.
