LTC2962CUD#TRPBF

Supervisors Overview

The LTC2962CUD#TRPBF is a quad configurable supervisor circuit manufactured by Analog Devices Inc. It provides voltage supervision for four independent inputs with an accuracy of 0.5%. The device operates within a supply voltage range of 2.25 V to 5.5 V and draws a typical operating current of 140 uA. It features adjustable threshold voltages, open drain and push-pull output types, and a manual reset capability. The reset delay time is specified at 200 ms. The component is housed in a QFN-16 package and functions without a watchdog timer or battery backup switch.

Supervisors Feature Summary

• Supports monitoring of four independent input channels simultaneously
• Offers configurable threshold settings for flexible voltage supervision
• Provides both open drain and push-pull output configurations
• Includes manual reset functionality for system control

Supervisors Applications

• Multi-rail power supply monitoring in embedded systems
• Voltage supervision for complex digital logic circuits
• System integrity monitoring in industrial control units
• Power management oversight in communication equipment

Supervisors Procurement Notes

Verify the specific suffix #TRPBF indicates tape and reel packaging when sourcing. Confirm the C grade temperature range meets operational requirements. Ensure compatibility with the target board's QFN-16 footprint. Check for RoHS compliance documentation. Validate that the adjusted thresholds align with the monitored rail specifications.

Supervisors Selection Notes

Select this component when multiple voltage rails require simultaneous supervision with high accuracy. The quad configuration reduces board space compared to individual supervisors. Consider the 140 uA quiescent current for power-sensitive designs. The adjustable thresholds allow adaptation to various standard voltage levels. Verify the output drive capability matches the downstream logic requirements.
