LTC2954IDDB-1#TRMPBF

Power Supply Controllers, Monitors Overview

The LTC2954IDDB-1#TRMPBF 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 with a typical supply current of 6µA. It is housed in an 8-DFN (3x2) package and supports an industrial temperature range of -40°C to +85°C.

Power Supply Controllers, Monitors Feature Summary

• Manages system power via a simple button interface
• Provides debounced button status through an interrupt output
• Enables control of system power states through the enable output

Power Supply Controllers, Monitors Applications

• Menu-driven applications requiring system shutdown requests
• Portable electronic devices needing power management
• Embedded systems utilizing push-button interfaces

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix TRMPBF indicates tape and reel packaging when ordering. Confirm the DDB variant corresponds to the 8-DFN (3x2) package type. Ensure the IDDB designation matches the required industrial temperature range specifications for your application environment before finalizing procurement.

Power Supply Controllers, Monitors Selection Notes

Select this component when a low-power solution for button-controlled power sequencing is required. The 6µA supply current makes it suitable for battery-operated devices. The interrupt output facilitates integration with microcontrollers for complex power state management without continuous polling.

Power Supply Controllers, Monitors Part Context

This part belongs to the LTC2954 family of push-button controllers. It shares functional similarities with variants like the LTC2954ITS8-1 but differs in package style and temperature rating. The DDB package offers a compact footprint compared to TSOT-23 options, fitting space-constrained designs.

Power Supply Controllers, Monitors Replacement Considerations

LTC2954CDDB-1#PBF is a pin-compatible alternative in a similar DFN package, though it may differ in temperature grade or packaging format.
