• Features low power consumption suitable for battery-operated applications
• Includes a fixed internal reset timeout to ensure stable power-up sequences

Supervisors Applications

• Microprocessor power supply supervision
• Digital controller reset generation
• Battery-powered system monitoring

Supervisors Procurement Notes

Verify the exact suffix configuration against official Analog Devices documentation, as variations exist between tape-and-reel and tube packaging formats. Confirm RoHS compliance status and lead-free specifications directly from the manufacturer's datasheet prior to procurement. Ensure the selected variant matches the required operating temperature range and package dimensions for your specific PCB layout constraints.

Supervisors Selection Notes

Select this component when a simple, low-cost supervisory solution is required for systems operating between 2.25 V and 5.5 V. Consider the fixed 140 ms timeout duration to ensure it aligns with your system's power-up requirements. Evaluate the 600 µA quiescent current against total system power budgets. Verify that the open-drain output interface is compatible with the downstream logic levels used in your design.

Supervisors Part Context

This part belongs to the LTC699 family of supervisory circuits designed for basic voltage monitoring tasks. It serves as a fundamental building block for ensuring system stability during power transitions. The series offers various pinout and threshold options to accommodate different standard voltage rails commonly found in embedded electronics and industrial control equipment.

Supervisors Replacement Considerations

Consult Analog Devices documentation for direct cross-reference alternatives within the same product family. Verify functional compatibility regarding reset thresholds and timeout durations before substituting with other manufacturers' parts.
