LTC2919HDDB-2.5#TRMPBF

Supervisors Overview

The LTC2919HDDB-2.5#TRMPBF is a precision triple/dual input voltage monitor manufactured by Analog Devices Inc. It operates within an industrial temperature range of -40°C to +125°C and is housed in a 10-pin DFN package. The device features a fixed 2.5V reference threshold for two channels, with the third channel offering adjustable thresholds. It provides open-drain active-low reset outputs and supports negative voltage monitoring capabilities.

Supervisors Feature Summary

• Supports simultaneous monitoring of three independent voltage rails including negative inputs
• Provides precise under-voltage and over-voltage detection with configurable thresholds
• Features open-drain active-low reset output compatible with various logic families

Supervisors Applications

• Industrial control system power supervision
• Telecommunications equipment voltage monitoring
• Automotive electronic module protection

Supervisors Procurement Notes

Verify the specific suffix #TRMPBF indicates tape and reel packaging when sourcing. Confirm the HDDB variant meets the required industrial temperature specifications for your application environment. Ensure compatibility with the 10-DFN footprint during PCB layout review.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous supervision with high accuracy. The dual fixed-threshold configuration simplifies design for standard logic levels while maintaining flexibility for custom voltages on the third channel. Consider thermal performance requirements given the dense package type.

Supervisors Part Context

This part belongs to the LTC2919 family of precision voltage monitors designed for multi-rail systems. It complements single-channel variants like the LTC2912 by offering consolidated supervision for complex power architectures without requiring multiple discrete components.

Supervisors Replacement Considerations

LTC2919CDDB-5#TRMPBF serves as a functional substitute with different threshold configurations.
