LTC2900-1IMS#PBF

Supervisors Overview

The LTC2900-1IMS#PBF is a programmable supply monitor designed for systems requiring supervision of up to four distinct power rails. It integrates sixteen preset or adjustable voltage monitoring combinations within a single component, enabling concurrent tracking of multiple supply voltages. The device features an active-low or open-drain reset output with an adjustable timer, ensuring reliable system recovery during fault conditions. Packaged in a compact 10-pin MSOP format, it supports automotive applications and operates across a specified temperature range.

Supervisors Feature Summary

• Monitors up to four independent supply voltages simultaneously
• Configurable via sixteen preset or user-adjustable voltage thresholds
• Provides active-low or open-drain reset signal with adjustable delay timer

Supervisors Applications

• Automotive electronic control units requiring multi-rail supervision
• Industrial systems managing multiple power distribution networks
• Embedded platforms needing precise voltage threshold detection

Supervisors Procurement Notes

Verify the specific suffix #PBF indicates tube packaging when reviewing distributor listings. Confirm that the -1 variant aligns with required automotive qualification standards if applicable. Cross-reference the manufacturer datasheet to ensure the selected package matches PCB footprint requirements. Validate availability status as supply constraints may affect immediate procurement timelines.

Supervisors Selection Notes

Select this component when designing circuits necessitating simultaneous oversight of four separate power lines. Evaluate the sixteen available monitoring configurations to determine if preset thresholds meet design specifications or if adjustable settings are required. Ensure the MSOP-10 package dimensions fit within the constrained board space allocated for supervisory logic.

Supervisors Part Context

This part belongs to Analog Devices' family of programmable supply monitors. It complements other supervisory ICs by offering multi-channel capability without requiring external comparators. The series focuses on providing flexible voltage threshold selection and reset timing control for complex power architectures.

Supervisors Replacement Considerations

Direct substitutes include other multi-channel supervisors from Analog Devices such as the LTC2908 or LTC2903 series, provided they support the required number of channels and package compatibility.
