LTC2963IUDC-1#TRPBF

Supervisors Overview

The LTC2963IUDC-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, drawing 140 uA of quiescent current. It provides open-drain and push-pull outputs, includes a manual reset function, and incorporates a watchdog timer. The reset delay time is fixed at 200 ms. The component 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
• Dual output types: open-drain and push-pull

Supervisors Applications

• Multi-rail power system monitoring
• Industrial control board supervision
• Embedded system reset management

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the industrial temperature grade (I) matches your operational environment requirements. Check official Analog Devices documentation for lead times as availability may be restricted. Ensure the QFN-20 footprint aligns with your PCB design constraints before finalizing procurement.

Supervisors Selection Notes

Select this model for applications requiring simultaneous monitoring of four distinct voltage rails with tight accuracy specifications. The integrated watchdog and manual reset capabilities simplify system protection logic. Consider the 140 uA quiescent current impact on overall power budget. Verify that the 2.25 V minimum operating voltage suits your lowest rail requirement.
