Package and temperature grade
The MAX813LESA+: The device monitors a single voltage input — no external divider needed for the 4.65V threshold; it is internally set. For systems running on a 5V rail with a tight tolerance, this threshold catches brownouts before the logic rails drop out of spec.
Active production and sourcing reality
Analog Devices lists this part as Active in production with ROHS3 compliance. No end-of-life notice or successor has been issued — the MAX813LESA+ remains a current catalog item for new designs and replacement builds alike. Sourced through authorized distribution channels and independent surplus inventory.
