LTC2954IDDB-2#TRPBF

Power Supply Controllers, Monitors Overview

The LTC2954IDDB-2#TRPBF is a push-button on/off controller manufactured by Analog Devices Inc. It manages system power through a button interface, featuring an enable output to switch system power and an interrupt output for debounced button status. The device operates within a supply voltage range of 2.7V to 26.4V and draws a typical supply current of 6µA. It is housed in an 8-DFN (3x2) package with exposed pad, suitable for surface mount installation.

Power Supply Controllers, Monitors Feature Summary

• Manages system power via a single push-button interface
• Provides debounced button status through an interrupt output
• Controls system power state using a dedicated enable output

Power Supply Controllers, Monitors Applications

• Menu-driven applications requiring shutdown requests
• Portable electronic devices with power management needs
• Systems utilizing push-button user interfaces

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the IDDB variant meets industrial temperature requirements if applicable. Ensure the DFN-8 footprint matches the design layout. Check for RoHS compliance documentation as required by project specifications.

Power Supply Controllers, Monitors Selection Notes

Select this component for designs requiring low quiescent current and simple button control. Compare against the ITS8 package option if smaller form factor is needed. Verify input voltage compatibility with the 2.7V to 26.4V range. Consider the interrupt output functionality for complex state machines.

Power Supply Controllers, Monitors Part Context

This part belongs to the LTC2950/LTC2954 family of push-button controllers. It shares functional similarities with the LTC2950 but offers specific package and pinout variations. The series is designed for efficient power management in battery-operated systems.

Power Supply Controllers, Monitors Replacement Considerations

The LTC2954CDDB-1#PBF is a documented alternative within the same family. Verify package compatibility between DFN-8 variants. Check if the -1 suffix configuration matches the circuit requirements.
