LTC2963CUDC-1#TRPBF

Supervisors Overview

The LTC2963CUDC-1#TRPBF 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 operates within a supply voltage range of 2.25 V to 5.5 V and draws 140 uA of quiescent current. It provides open drain and push-pull outputs, includes a manual reset input, and integrates a watchdog timer. The reset delay time is fixed at 200 ms. It is housed in a QFN-20 package and supports surface mount installation.

Supervisors Feature Summary

• Quad configurable voltage supervision with high precision
• Integrated watchdog timer for system reliability
• Flexible output configuration with open drain and push-pull options

Supervisors Applications

• Multi-rail power supply monitoring in industrial systems
• Embedded controller supervision in communication equipment

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the manufacturer part number matches exactly to ensure correct pinout and electrical characteristics. Check for RoHS compliance documentation as required by project specifications. Validate availability status through authorized distributors due to potential supply constraints.

Supervisors Selection Notes

Select this component when multiple independent voltage rails require precise monitoring within a compact footprint. The low quiescent current makes it suitable for power-sensitive applications. Ensure the operating temperature range meets environmental requirements. Verify that the adjustable threshold capabilities align with the specific voltage levels being monitored in the design.

Supervisors Part Context

This part belongs to the LTC2963 series of supervisory circuits from Analog Devices. It is designed for applications requiring multiple voltage monitors in a single package. The series offers configurable thresholds and various output types to accommodate different system architectures. It falls under the PMIC category for power management integrated circuits.

Supervisors Replacement Considerations

Check for direct substitutes within the LTC2963 family with compatible packages. Verify equivalent electrical parameters such as accuracy and supply voltage range. Ensure any replacement maintains the same pinout or requires board redesign. Consult official cross-reference lists for validated alternatives.
