Product details

3.075V threshold supervisor for industrial rails

Rated for -40°C to 125°C operation, this part is suited for industrial and automotive-temperature environments where the power rail must be held in reset until the supply stabilizes. The reset timeout is Adjustable/Selectable via an external capacitor, giving the designer control over the delay before the part releases the reset signal after the supply rises above the threshold.

Active High reset — confirm polarity before the board spins

The Push-Pull output eliminates the need for an external pull-up resistor, simplifying the BOM and saving board area in dense designs.

RoHS non-compliant — plan for the exemption

The MAX6422US31-T is listed as RoHS non-compliant. This is a sourcing gate for any design targeting full RoHS conformance — the part is suited for legacy production, repair, or applications with a valid RoHS exemption for lead content.

SOT-23-4 footprint — what to expect on the layout

The part is supplied in a SOT-23-4 package (also referenced as TO-253-4), a 4-lead surface-mount package.

Frequently asked questions

Is MAX6422US31-T ROHS compliant?

No, the part is listed as RoHS non-compliant. It is intended for designs with a RoHS exemption or for legacy/repair applications where lead content is permitted.

Can MAX6422US31-T replace MAX6422US31+?

The MAX6422US31+ is the lead-free (RoHS-compliant) variant of the same supervisor. The MAX6422US31-T is functionally identical but RoHS non-compliant. Check your assembly house's material declaration requirements before substituting one for the other.
