Power Supply Controllers, Monitors Procurement Notes

Verify the specific suffix #PBF indicates lead-free compliance and tube packaging when sourcing. Confirm the IMS variant corresponds to the MSOP-12 package dimensions. Cross-reference the -2 suffix against official Analog Devices documentation to ensure the correct threshold voltage configuration is selected for your design requirements.

Power Supply Controllers, Monitors Selection Notes

Select this component when a wide input voltage range up to 36V is required alongside a fixed 900mV threshold. Consider the manual reset feature if external system control over the reset state is necessary. Ensure the MSOP-12 footprint aligns with available PCB space and thermal management capabilities.

Power Supply Controllers, Monitors Part Context

This part belongs to the LTC2956 series of supervisory circuits from Analog Devices. It shares functional similarities with other parts in the family but differs in package type and specific electrical parameters. The IMS-2 designation distinguishes it from other variants like the LTC2956IMS-1#PBF which may have different threshold settings or pin configurations.

Power Supply Controllers, Monitors Replacement Considerations

Direct substitutes include other Analog Devices supervisory circuits with compatible voltage ranges and thresholds. Verify pin-to-pin compatibility and electrical specifications before replacing. Consult the manufacturer's cross-reference guide for approved alternative part numbers.
