The 4.4V threshold targets 5V nominal rails — the supervisor trips before the rail falls below the minimum operating voltage of 5V logic, preventing undefined states in the processor or memory during brownout or power-down. ## Package and temperature grade This limits deployment to indoor, temperature-controlled environments — not suitable for automotive or extended industrial ambient without active cooling. Listed as Active in production with ROHS3 compliance.","metaTitle":"MAX818MCSA+ Battery Backup Circuit, Active Low Reset","metaDescription":"MAX818MCSA+ from Analog Devices — Battery Backup Circuit supervisor, Active Low reset, 140ms timeout, 4.4V threshold.
