It monitors a single voltage with a threshold of 4.37V and provides both active-high and active-low reset outputs in a push-pull, totem-pole configuration — covering both reset polarities without needing an external pull-up resistor. ## Lifecycle and compliance status The part is listed as RoHS non-compliant, so it does not meet the EU RoHS directive for lead-free assembly; verify your board's regulatory requirements before specifying.","metaTitle":"MAX820MCSE Power Supply Monitor, 4.37V Threshold, 16-SOIC","metaDescription":"MAX820MCSE from Analog Devices — active Power Supply Monitor IC with push-pull reset outputs, 4.37V threshold, 140ms timeout. 16-SOIC.
