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.","metaTitle":"MAX6422US31-T Simple Reset/Power-On Reset IC","metaDescription":"MAX6422US31-T Simple Reset/Power-On Reset IC.
