TPS2102D

Overview

The TPS2102D is a power-distribution switch manufactured by Texas Instruments. It operates within an input voltage range of 2.7V to 4V and supports supply currents up to 14µA. The device provides two independent channels with a 2:1 input-to-output ratio, utilizing internal N-channel and P-channel FETs for source selection switching. It features a maximum output current capacity of 500mA per channel and 100mA for specific configurations. Designed for surface-mount installation, the component is housed in an 8-SOIC package with a width of 3.90mm.

Feature Summary

• Integrates dual independent power distribution switches for flexible source management
• Utilizes internal N-channel and P-channel field-effect transistors for efficient switching
• Supports automatic source selection between multiple power inputs

Applications

• Handheld mobile devices requiring multi-source power management
• Portable electronics needing redundant power supply switching
• Battery-powered systems requiring seamless power path control

Procurement Notes

Verify the exact ordering suffix against the manufacturer's official documentation to confirm package type and tape-and-reel specifications. Confirm RoHS compliance status and environmental classification details prior to procurement. Ensure that the selected variant matches the required operating temperature range and electrical characteristics for the target application environment.

Selection Notes

Select this component when designing circuits requiring dual-input power source selection for portable applications. Evaluate the 500mA output current capability against peak load requirements. Consider the 8-SOIC package dimensions for PCB layout constraints. Verify compatibility with the 2.7V to 4V operating voltage range of the system power rails.

Part Context

The TPS2102D belongs to the VAUX power-distribution switch family from Texas Instruments. This series focuses on providing reliable power routing solutions for low-voltage digital and analog loads. The device complements other TI power management ICs by offering simple, effective source selection without complex external control circuitry.

Replacement Considerations

Consult the official datasheet for direct cross-reference part numbers. Verify pinout compatibility and electrical parameter equivalence before substituting.
