The output is Active Low, Open Drain — it pulls the reset line low when the monitored voltage crosses the threshold. ## Industrial temperature range and SOT-23-3 package The SOT-23-3 package (also listed as TO-236-3 or SC-59) is a three-pin surface-mount footprint with 0.95mm pitch, fitting a standard supervisor layout without requiring a dedicated power-good pin. The single-channel monitoring (Number of Voltages Monitored: 1) means this part watches one rail. For multi-rail systems (core + I/O + memory), you would stack multiple DS1818 devices or move to a multi-voltage supervisor. The EconoReset family is positioned as a cost-optimised line — no manual reset input, no watchdog timer, just the basic reset function. ## Active lifecycle and compliance documentation The SOT-23-3 package is MSL1 (moisture sensitivity level 1, per JEDEC standard for the package type), meaning no bake-out required before reflow.","metaTitle":"DS1818R-5+T&R Analog Devices EconoReset Supervisor, 3.06V","metaDescription":"Analog Devices DS1818R-5+T&R Simple Reset/Power-On Reset IC, Active Low, Open Drain, 3.06V threshold, SOT-23-3.
