LTC2919IDDB-2.5#TRPBF

Supervisors Overview

The LTC2919IDDB-2.5#TRPBF is a precision triple/dual input voltage monitor manufactured by Analog Devices Inc. It features an open-drain output and supports negative voltage monitoring. The device operates within a supply voltage range of 1V to 6V, with a maximum reset delay time of 200ms. It offers high accuracy of 1.5% and consumes only 50uA of operating current. The component is housed in a 10-WFDFN package with exposed pad, suitable for surface mount installation across industrial temperature ranges.

Supervisors Feature Summary

• Provides precise supervision for up to three independent input voltages including negative rails
• Features adjustable threshold detection capabilities for flexible system configuration
• Delivers active-low open-drain reset signal with programmable timeout delays

Supervisors Applications

• Industrial control systems requiring multi-rail power supervision
• Automotive electronics monitoring critical voltage levels
• Telecommunications infrastructure power management units

Supervisors Procurement Notes

Verify the specific suffix designations against official Analog Devices documentation to ensure correct temperature grade and packaging specifications. Confirm RoHS compliance status and material declarations prior to integration. Cross-reference the exact part number with manufacturer datasheets to validate pinout compatibility and electrical characteristics for your specific application requirements.

Supervisors Selection Notes

Select this component when designing systems requiring simultaneous monitoring of multiple voltage rails with high precision. Consider the 10-WFDFN package constraints for PCB layout optimization. Evaluate the 50uA quiescent current against total system power budgets. Ensure the open-drain output interface aligns with the downstream logic or microcontroller reset input requirements.

Supervisors Part Context

This part belongs to the LTC2919 family of precision voltage monitors from Analog Devices. It shares functional similarities with other members like the LTC2919CDDB variants but differs in specified temperature ranges and factory packaging formats. The IDDB suffix typically denotes industrial grade performance within the broader supervisory circuit portfolio designed for robust power management applications.

Supervisors Replacement Considerations

LTC2919CDDB-2.5#TRPBF serves as a potential alternative with commercial temperature range specifications. Verify thermal performance limits and threshold accuracy tolerances before substitution. Ensure package dimensions and pin configurations remain compatible with existing board layouts.
