LTC2963CUDC-1#PBF

Supervisors Overview

The LTC2963CUDC-1#PBF is a quad configurable supervisor circuit manufactured by Analog Devices Inc. It operates within a supply voltage range of 2.25 V to 5.5 V and consumes 140 uA of quiescent current. The device features four monitored inputs with adjustable threshold voltages and offers open drain or push-pull output types. It includes a manual reset function, a watchdog timer, and provides a fixed reset delay time of 200 ms. The accuracy is specified at 0.5%, and it functions reliably between 0°C and +70°C in a QFN-20 package.

Supervisors Feature Summary

• Provides monitoring for four independent input channels with configurable thresholds
• Integrates a watchdog timer for system fault detection
• Supports both open drain and push-pull output configurations
• Includes a manual reset capability for controlled system recovery

Supervisors Applications

• Multi-rail power supply supervision in embedded systems
• Watchdog timer implementation for microcontroller protection
• Manual reset control circuits for industrial equipment

Supervisors Procurement Notes

Verify component authenticity through authorized distributors as availability may be restricted. Confirm the specific suffix matches the required pinout and functionality. Check RoHS compliance documentation for regulatory adherence. Ensure the operating temperature range aligns with the intended application environment. Validate packaging details against procurement specifications.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous supervision within a compact footprint. Consider the 140 uA quiescent current for low-power design constraints. Evaluate the need for adjustable thresholds versus fixed options in other variants. Assess the compatibility of the QFN-20 package with available PCB real estate. Verify that the 200 ms reset delay meets system timing requirements.

Supervisors Part Context

This part belongs to the LTC2963 series of supervisory circuits designed for comprehensive power management. It complements other Analog Devices PMIC solutions by offering multi-channel monitoring capabilities. The device addresses the need for reliable system reset mechanisms in complex electronic designs requiring precise voltage tracking.

Supervisors Replacement Considerations

Consult official datasheets for cross-reference information regarding compatible alternatives. Verify pin compatibility and electrical specifications before substitution. Ensure any replacement maintains the same package type and thermal characteristics.
