LTC2919CDDB-2.5#TRPBF

Supervisors Overview

The LTC2919CDDB-2.5#TRPBF is a precision supervisory circuit manufactured by Analog Devices Inc., designed for monitoring multiple voltage rails in embedded systems. It features three independent input channels capable of detecting under-voltage, over-voltage, and negative voltage conditions. The device utilizes an open-drain output configuration to signal fault states. It operates within a supply voltage range up to 6V and maintains high accuracy with a threshold tolerance of 1.5%. The component is housed in a compact 10-WFDFN package with exposed pad, suitable for surface-mount assembly.

Supervisors Feature Summary

• Supports simultaneous monitoring of three distinct voltage inputs for comprehensive power rail supervision
• Provides precise detection capabilities for under-voltage, over-voltage, and negative voltage anomalies
• Features an open-drain reset output compatible with various logic families for flexible system integration

Supervisors Applications

• Multi-rail power supply monitoring in industrial control systems
• Voltage supervision for portable electronic devices requiring low quiescent current
• Processor supervisor circuits in automotive embedded applications

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape-and-reel packaging when sourcing. Confirm the 'C' grade designation corresponds to the commercial temperature range requirements of your design. Ensure compatibility with the 10-WFDFN footprint during PCB layout finalization. Cross-reference the manufacturer's latest datasheet for any recent pinout or electrical specification updates before procurement.

Supervisors Selection Notes

Select this component when designing systems requiring triple-channel voltage supervision with high accuracy. The fixed 2.5V threshold variant simplifies external resistor network design compared to adjustable versions. Consider the 1.5% accuracy specification against system tolerance requirements. Evaluate the 50uA quiescent current impact on battery life if used in power-sensitive applications.
