Product details

3.08V threshold supervisor in an SC-70-3

The MAX6327XR31 from Maxim Integrated is a single-channel voltage supervisor that asserts an active-high reset when the monitored supply drops below 3.08V. It holds the reset output high for a minimum of 100ms after the supply recovers above the threshold. The push-pull, totem-pole output eliminates the need for an external pull-up resistor, simplifying the interface to the target processor's reset input — provided that processor expects an active-high reset signal. The SC-70-3 package occupies minimal board area, suited for space-constrained designs in industrial control, telecom line cards, and portable instrumentation where a 3.3V rail needs clean power-on reset behavior.

Active production — no LTB pressure on this line item

The MAX6327XR31 carries an active lifecycle status. There is no last-time-buy notice, no NRND flag, and no announced discontinuation. For a procurement review, this part is a safe BOM commitment for current and next-year production runs.

Temperature grade and environment

Rated for -40°C to 85°C ambient operation. The SC-70-3 surface-mount package reflows with standard lead-free profiles.

Frequently asked questions

Does MAX6327XR31 have an active high or active low reset?

The MAX6327XR31 has an active-high reset output. The output goes high when the supply drops below the 3.08V threshold and remains high for the 100ms minimum reset timeout after recovery.

Is MAX6327XR31 equivalent to MAX6326?

The MAX6326 series typically provides an active-low reset output, while the MAX6327XR31 provides an active-high reset. They are complementary in function but not pin-for-pin drop-in equivalents due to the reset polarity difference. Verify your processor's reset input polarity before substituting one for the other.
