LTC2919CMS-5#PBF

Supervisors Overview

The LTC2919CMS-5#PBF is a precision voltage monitor manufactured by Analog Devices Inc., designed for supervising multiple power rails. It features three monitored inputs with an open-drain output type and supports threshold voltages of 5 V or adjustable settings. The device operates within a supply voltage range up to 6 V and maintains an accuracy of 1.5%. It consumes a typical operating current of 50 uA and includes a reset delay time of 200 ms. The component is housed in a 10-MSOP package, suitable for surface mount installation, and functions reliably across a temperature range from 0°C to +70°C.

Supervisors Feature Summary

• Provides precise supervision for up to three independent input voltage rails simultaneously
• Features low quiescent current consumption suitable for battery-powered applications
• Delivers open-drain reset output for flexible logic interface compatibility

Supervisors Applications

• Portable electronic devices requiring multi-rail power monitoring
• Industrial control systems needing reliable voltage supervision
• Communication equipment utilizing multiple power domains

Supervisors Procurement Notes

Verify the specific suffix designation to confirm the exact threshold voltage configuration, as variations exist within the family. Ensure the MSOP-10 package dimensions align with your PCB footprint requirements. Confirm RoHS compliance status through official manufacturer documentation before finalizing procurement decisions.

Supervisors Selection Notes

Select this component when simultaneous monitoring of three distinct voltage lines is required without manual reset functionality. Consider the 1.5% accuracy specification against system tolerance requirements. Evaluate the 50 uA operating current impact on overall system power budget compared to higher-performance alternatives.

Supervisors Part Context

This part belongs to the LTC2919 series of precision voltage monitors from Analog Devices. The series offers various configurations for different input counts and threshold options. The CMS-5 variant specifically denotes the MSOP-10 package with a fixed 5 V threshold option, distinguishing it from adjustable or other package variants in the same product line.

Supervisors Replacement Considerations

LTC2919CMS-3.3#PBF serves as a functional substitute with identical package and pinout but utilizes a 3.3 V threshold instead of 5 V. Verify that the system design accommodates the different trip point voltage before implementing any cross-threshold replacement.
