LTC2964HUDC#PBF

Supervisors Overview

The LTC2964HUDC#PBF is a quad configurable supervisor circuit manufactured by Analog Devices Inc. It provides voltage supervision for four independent inputs with 0.5% accuracy. The device operates within a supply voltage range of 2.25 V to 5.5 V and features adjustable threshold voltages. It supports manual reset functionality and offers open-drain or push-pull output types. The component is housed in a 20-lead UTQFN package (3mm x 4mm) and is rated for industrial temperatures from -40°C to +125°C.

Supervisors Feature Summary

• Quad configurable voltage supervision for multiple system rails
• High accuracy monitoring with 0.5% threshold precision
• Flexible output configuration supporting open-drain and push-pull modes
• Industrial temperature rating for robust environmental operation

Supervisors Applications

• Multi-rail power supply monitoring in embedded systems
• Voltage supervision for complex digital logic boards
• System integrity monitoring in industrial control units

Supervisors Procurement Notes

Verify the specific suffix and package variant against the official datasheet to ensure compatibility with design requirements. Confirm that the 20-lead UTQFN footprint matches the PCB layout specifications. Check for any regional distribution restrictions or availability constraints prior to finalizing procurement plans.

Supervisors Selection Notes

Select this component when multi-channel voltage supervision is required with high precision. Ensure the input voltage ranges align with the monitored rails. Consider the package size constraints and thermal performance needs for the target application environment.

Supervisors Part Context

This part belongs to the LTC2962/LTC2964 family of supervisory circuits designed for accurate voltage monitoring. It shares functional similarities with other quad supervisors but is distinguished by its specific package and extended temperature range capabilities.

Supervisors Replacement Considerations

The LTC2962 series may serve as a related alternative, though pin counts and channel configurations differ. Verify electrical parameters and package dimensions before substitution.
