LTC2954IDDB-2#TRMPBF

Power Supply Controllers, Monitors Overview

The LTC2954IDDB-2#TRMPBF is a push-button on/off controller manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.7V to 26.4V and draws a typical supply current of 6 µA. The device is housed in an 8-WFDFN (3x2) surface-mount package with exposed pad. It supports industrial temperature ranges from -40°C to +125°C.

Power Supply Controllers, Monitors Feature Summary

• Enables system power control via momentary push-button input
• Provides configurable output drive for high-side or low-side switching
• Includes integrated debounce circuitry to prevent false triggering

Power Supply Controllers, Monitors Applications

• Portable electronic devices requiring manual power management
• Industrial equipment with remote switch interfaces
• Battery-powered systems needing low quiescent current operation

Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix #TRMPBF indicates tape-and-reel packaging with lead-free compliance. Confirm the IDDB variant meets the required industrial temperature range specifications. Ensure the 8-WFDFN footprint matches the design layout. Check for RoHS directives compliance documentation before finalizing procurement.

Power Supply Controllers, Monitors Selection Notes

Select this component when a dedicated push-button interface is required for power sequencing. Consider the 6 µA supply current for battery life optimization. Verify that the 2.7V to 26.4V input range covers the system's operating voltage. Ensure the DFN-8 package fits the available board space constraints.

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 different pinout and configuration options. The series is designed for simple, reliable power control in compact applications without complex microcontroller involvement.

Power Supply Controllers, Monitors Replacement Considerations

LTC2954CDDB-2#PBF is a tray-packaged alternative with identical electrical characteristics. LTC2954ITS8-2#TRPBF offers the same function in a TSOT-23-8 package. Verify package compatibility and thermal performance when substituting.
