Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging configuration. Confirm the IDDB variant corresponds to the industrial temperature range (-40°C to +85°C). Ensure the DFN-8 footprint matches the target PCB layout requirements. Cross-reference the manufacturer part number with official Analog Devices documentation to validate pinout and electrical characteristics against design specifications.

Power Supply Controllers, Monitors Selection Notes

Select this component when a micro-power solution is required for managing system power states via a mechanical switch. The 6 µA supply current makes it suitable for battery-operated applications where standby consumption must be minimized. The wide input voltage range accommodates various single-cell or multi-cell battery configurations without external level shifting.

Power Supply Controllers, Monitors Part Context

This part belongs to the LTC2950 series of push-button controllers. It shares functional similarities with the LTC2951 and LTC2954, differing primarily in package type and specific output configurations. The IDDB-1 designation specifies the industrial temperature grade and the DFN-8 package style, distinguishing it from other variants in the family.

Power Supply Controllers, Monitors Replacement Considerations

LTC2950IDDB-2#TRPBF: Different output configuration (open-drain vs. push-pull/enables different FET topologies). LTC2951IDDB-1#TRPBF: Similar function but may have different timing or output drive characteristics; verify datasheet compatibility.
