LTC2962IUD#PBF

Supervisors Overview

The LTC2962IUD#PBF is a quad configurable voltage supervisor manufactured by Analog Devices Inc. It features four independent 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 consumes 140 uA of quiescent current. It provides open-drain and push-pull outputs, includes manual reset functionality, and has a fixed reset delay of 200 ms. The component is housed in a QFN-16 package and supports an operating temperature range from -40°C to +85°C.

Supervisors Feature Summary

• Quad configurable voltage supervision with adjustable thresholds for multiple power rails
• High accuracy performance specified at 0.5% threshold tolerance
• Flexible output configuration supporting both open-drain and push-pull modes
• Integrated manual reset input for system control

Supervisors Applications

• Multi-rail power supply monitoring in embedded systems
• Voltage supervision for complex digital logic circuits
• Industrial control unit power integrity verification

Supervisors Procurement Notes

Verify the specific suffix PBF confirms lead-free compliance and RoHS status before procurement. Confirm the QFN-16 package dimensions match your PCB footprint requirements. Ensure the 2.25 V minimum supply voltage aligns with your system's lowest operating rail. Validate that the 200 ms reset delay meets your system startup timing constraints. Check availability status as distribution may vary by region.

Supervisors Selection Notes

Select this component when precise monitoring of four distinct voltage levels is required. The adjustable thresholds allow customization for various standard voltage rails without external resistors. The low quiescent current makes it suitable for battery-powered applications where efficiency is critical. Consider the manual reset feature if deterministic system recovery is necessary during fault conditions.
