LTC2964IUDC#PBF

Supervisors Overview

The LTC2964IUDC#PBF is a quad configurable voltage supervisor manufactured by Analog Devices Inc. It provides four independent monitoring channels with adjustable thresholds and 0.5% accuracy. The device operates within a supply voltage range of 2.25 V to 5.5 V and features open-drain or push-pull outputs. It includes manual reset functionality and a 200 ms reset delay timer. Designed for industrial applications, it functions reliably between -40°C and +85°C in a compact 20-lead QFN package.

Supervisors Feature Summary

• Quad configurable supervision with adjustable threshold voltages
• High precision monitoring with 0.5% accuracy specification
• Flexible output configuration supporting open-drain or push-pull modes
• Integrated manual reset capability with defined delay timing

Supervisors Applications

• Multi-rail power system monitoring
• Industrial control board supervision
• Embedded system voltage integrity verification

Supervisors Procurement Notes

Verify the specific suffix IUDC against official datasheets to confirm pinout and thermal pad requirements. Ensure compatibility with existing PCB footprints before procurement. Confirm RoHS compliance status through manufacturer documentation. Validate operating temperature ranges match application environmental constraints. Cross-reference ordering information with authorized distributors to ensure authenticity.

Supervisors Selection Notes

Select this component when multiple independent voltage rails require simultaneous supervision with high accuracy. The adjustable thresholds allow customization for various logic levels without external resistors. Consider the QFN package size for space-constrained designs. Evaluate the need for manual reset functionality versus automatic recovery based on system safety requirements.

Supervisors Part Context

This part belongs to the LTC2962/LTC2964 family of supervisory circuits from Analog Devices. It shares architectural similarities with the LTC2962 but offers four channels instead of two. The IUDC designation indicates a specific lead-free tape and reel packaging variant within the broader product line.

Supervisors Replacement Considerations

LTC2962IUD#PBF serves as a dual-channel alternative if only two monitored rails are required. Verify pin compatibility and channel count differences before substitution.
