LTC2963IUDC-1#PBF

Supervisors Overview

The LTC2963IUDC-1#PBF is a quad configurable supervisor circuit manufactured by Analog Devices Inc. It features four independent voltage monitoring channels with adjustable thresholds and 0.5% accuracy. The device supports manual reset, watchdog timer functionality, and offers open-drain or push-pull outputs. Operating from 2.25 V to 5.5 V, it consumes 140 uA of supply current. The component operates within a temperature range of 0°C to +70°C and is housed in a QFN-20 package.

Supervisors Feature Summary

• Provides four independently configurable voltage supervision channels for comprehensive system monitoring.
• Integrates a watchdog timer and manual reset capability for enhanced system reliability.
• Delivers high threshold accuracy of 0.5% with adjustable detection levels.

Supervisors Applications

• Multi-rail power supply monitoring in industrial systems
• Voltage supervision for embedded processor architectures
• Watchdog timer implementation in safety-critical circuits

Supervisors Procurement Notes

Verify the specific suffix 'I' indicates the industrial temperature grade (0°C to +70°C) distinct from commercial variants. Confirm the QFN-20 package footprint matches PCB design requirements. Ensure the adjustable threshold configuration aligns with target rail voltages. Check official documentation for any recent lifecycle status changes or obsolescence notices.

Supervisors Selection Notes

Select this component when multiple independent voltage rails require precise supervision within a compact form factor. The adjustable thresholds allow flexibility for various standard voltage levels. Consider the 140 uA quiescent current for power-sensitive applications. Verify that the required output drive type (open-drain vs. push-pull) meets downstream logic interface specifications.

Supervisors Part Context

This part belongs to the LTC2963 series of supervisory circuits designed for multi-channel voltage monitoring. It complements other Analog Devices PMIC solutions by providing dedicated fault detection and reset management. The QFN-20 package allows for space-constrained designs while maintaining thermal performance suitable for industrial environments.
