The SOT-23-6 package keeps the footprint small, and the industrial temperature range (-40°C to 85°C) means it can live in a motor drive enclosure or outdoor telecom cabinet without issue. ## Voltage thresholds and reset timing — the numbers that matter The reset timeout is a minimum of 140ms. That is a deliberate, relatively long delay — it gives bulk capacitors on the supply rails time to charge up before the processor's reset pin is released. ## Active production, no end-of-life concerns It is listed as RoHS non-compliant, so if your assembly line or customer requires RoHS, verify your exemption or look for a lead-free variant in the same family.","metaTitle":"MAX6721UTVHD3-T Multi-Voltage Supervisor","metaDescription":"MAX6721UTVHD3-T multi-voltage supervisor from Maxim Integrated.

The MAX6721UTVHD3-T monitors 1.313V and 1.575V; check the MAX6720 datasheet to see if those thresholds match your rails.
