TPS2114APW

Overview

The TPS2114APW is a source selector switch manufactured by Texas Instruments, housed in an 8-TSSOP surface-mount package. It operates as a 2:1 power multiplexer with N-channel internal switches. The device supports input voltages from 2.8 V to 5.5 V and delivers a maximum output current of 750 mA. Key electrical parameters include a maximum on-resistance of 140 mΩ, a turn-on delay of up to 500 µs, and a turn-off delay of up to 3 ms. It functions within a temperature range of -40°C to +85°C.

Feature Summary

• Integrates two N-channel MOSFETs for 2:1 source selection
• Provides automatic priority-based switching between inputs
• Includes built-in protection against reverse current flow
• Features thermal shutdown and under-voltage lockout mechanisms

Applications

• Handheld mobile devices
• Portable consumer electronics
• Battery-powered systems requiring redundant power sources

Procurement Notes

Verify the specific ordering suffix 'PW' corresponds to the 8-TSSOP package configuration when sourcing components. Confirm that the device meets the required industrial operating temperature range of -40°C to +85°C for your specific application environment. Ensure compatibility with the 2.8 V to 5.5 V supply voltage constraints during system design validation.

Selection Notes

Select this component for applications requiring seamless power path management between two distinct voltage sources. The TPS2114APW is suitable where low quiescent current and compact surface-mount packaging are critical. Consider the 750 mA output limit and 140 mΩ on-resistance to ensure efficient power delivery without excessive heat generation in space-constrained designs.

Part Context

This part belongs to the TPS211x series of power muxes designed for portable electronics. It serves as an OR controller or source selector, allowing systems to switch between primary and backup power supplies automatically. The family focuses on minimizing board space while maintaining reliable power distribution in battery-operated devices.

Replacement Considerations

The TPS2110APW is a documented substitute within the same product family, offering similar source selection functionality in an 8-TSSOP package. Verify pin-to-pin compatibility and electrical parameter alignment before implementation.
