Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix TRPBF indicates tape and reel packaging when ordering. Confirm the -2 variant designation matches the required threshold settings for your application. Check current availability status as distribution may be limited or restricted in certain regions. Ensure compatibility with your PCB footprint for the 8-DFN package type before finalizing procurement decisions.

Power Supply Controllers, Monitors Selection Notes

Select this component when a low-power push-button interface is required for system power control. Consider the 2.7V to 26.4V input range suitability for your supply rails. Evaluate the 6uA standby current against battery life requirements. Compare the 8-DFN package size against available board space constraints relative to alternative supervisory ICs.

Power Supply Controllers, Monitors Part Context

This part belongs to the LTC2950/LTC2951 family of supervisory circuits from Analog Devices. It shares functional similarities with the LTC2950 but offers specific threshold configurations. The series is designed for applications requiring robust power management with minimal external components. It complements other PMIC solutions by providing dedicated on/off control logic.

Power Supply Controllers, Monitors Replacement Considerations

Direct substitutes include the LTC2951CDDB-2#PBF for tray packaging or the LTC2951CDDB-2#TRMPBF for tube packaging. Verify pinout compatibility and electrical specifications match exactly before substitution.
