Product details

What this supervisor does and where it fits

This is the kind of part you find on boards with dual low-voltage core supplies — think FPGAs with separate VCCINT and VCCAUX rails, or a DSP core plus its I/O voltage. 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.

Frequently asked questions

What is the typical reset timeout for MAX6721UTVHD3-T?

The reset timeout is a minimum of 140ms. The output stays low for at least that long after all monitored voltages rise above their thresholds.

Can MAX6721UTVHD3-T be used to replace MAX6720?

The MAX6720 is a different variant in the same family with different voltage thresholds. The MAX6721UTVHD3-T monitors 1.313V and 1.575V; check the MAX6720 datasheet to see if those thresholds match your rails. Pin compatibility depends on the specific variant — verify the pinout before substituting.
