Supervisors Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status and lead-free certification prior to procurement. Check for end-of-life notices as this specific variant may be obsolete. Ensure storage conditions meet moisture sensitivity level requirements to prevent package damage during assembly.

Supervisors Selection Notes

Select this component when a fixed 4.39V threshold is required for system supervision. Consider the 20ms reset timeout duration against system startup requirements. Evaluate the open-drain output configuration for compatibility with downstream logic levels. Verify that the SOT-143-4 package fits the available PCB footprint constraints.

Supervisors Part Context

This part belongs to the MAX6315 series of microprocessor supervisory circuits from Analog Devices/Maxim Integrated. The series offers various threshold voltages and timeout periods to suit different application needs.
