That industrial temperature grade covers most factory-floor and outdoor telecom enclosures. The SOIC-8 footprint is a standard one — no surprises for the pick-and-place, and easy to hand-rework if needed. No lab, no bench, let us go — a technician can swap this on site with basic tools. ## Lifecycle and sourcing The MAX819LESA+ carries an Active lifecycle status with ROHS3 compliance.","metaTitle":"MAX819LESA+ Battery Backup Circuit, 4.65V Threshold, 8-SOIC","metaDescription":"MAX819LESA+ is an active battery backup supervisor IC with active-low reset, 140ms min timeout, and 4.65V threshold.
