Supervisors Procurement Notes

Verify the exact suffix and revision level when ordering, as availability may vary. Confirm that the 8-SOIC package matches your PCB footprint requirements. Ensure the selected voltage threshold aligns with your system's operating rails. Check for RoHS compliance status if required by your manufacturing standards. Validate lead times due to potential limited supply conditions for this specific part number.

Supervisors Selection Notes

Select this component when a single-channel voltage supervisor with integrated watchdog functionality is required. It is suitable for applications needing a 1-second reset delay and manual reset capability. Consider the -55°C to +125°C industrial temperature range for harsh environments. Verify that the open-drain output interface is compatible with your microprocessor's reset pin logic levels.
