Supervisors Procurement Notes

Verify the exact part number suffix against official Analog Devices documentation to confirm package type and temperature grade. Confirm availability status as distributor listings may indicate obsolete or limited stock conditions. Ensure compatibility with existing board layout and thermal requirements before procurement.

Supervisors Selection Notes

Select this component when a simple voltage supervisor with manual reset is required without watchdog features. Consider the SOT-23-5 package size and operating temperature range for environmental suitability. Verify that the 3.08 V threshold aligns with the monitored rail voltage specifications.

Supervisors Part Context

This component belongs to the ADM825 series of supervisory circuits from Analog Devices. It is categorized under PMIC - Supervisors. Similar parts in the series may include variants with different thresholds or additional features like watchdog timers, but this specific model focuses on basic voltage monitoring and manual reset capabilities.

Supervisors Replacement Considerations

Check for direct substitutes within the ADM825 family or other Analog Devices supervisors with matching threshold voltages and package types. Ensure functional equivalence regarding reset delay and output configuration.
