LTC2919HDDB-2.5#TRPBF

Supervisors Overview

The LTC2919HDDB-2.5#TRPBF is a precision voltage monitor from Analog Devices, designed for supervising multiple power rails in embedded systems. It features three independent monitoring channels capable of detecting under-voltage, over-voltage, and negative voltage conditions. The device utilizes an open-drain output to signal fault states. It operates within a supply voltage range up to 6V and maintains high accuracy across industrial temperature ranges. The component is housed in a compact 10-pin DFN package with an exposed pad, facilitating efficient thermal management and space-constrained PCB layouts.

Supervisors Feature Summary

• Supports simultaneous monitoring of three distinct input voltages including negative rail detection
• Provides precise threshold comparison with adjustable or fixed reference options depending on variant
• Features active-low open-drain fault output compatible with standard logic interfaces

Supervisors Applications

• Industrial control system power supervision
• Embedded processor board voltage monitoring
• Automotive electronics power integrity verification

Supervisors Procurement Notes

Verify the specific suffix designation against official Analog Devices documentation to confirm pinout compatibility and electrical characteristics. Ensure the ordering part number matches the required package type and temperature grade. Cross-reference datasheet revisions to validate manufacturing changes such as bond wire material updates. Confirm RoHS compliance status through current manufacturer declarations before finalizing procurement specifications.

Supervisors Selection Notes

Select this component when multi-rail supervision with negative voltage capability is required. Compare channel count and threshold precision against alternative monitors in the LTC291x family. Evaluate package size constraints relative to available footprint options like MSOP or larger DFN variants. Assess operating temperature requirements to ensure the HD sub-series meets environmental specifications for the target application environment.
