The open-drain output lets you connect the reset line to any pull-up voltage up to the absolute maximum of the output transistor.
For a production BOM, this part is a low-risk line item — no imminent obsolescence to plan around.
The reset output is active-low, open-drain. It requires an external pull-up resistor to the logic supply rail. When the monitored voltage falls below 4.63V, the output pulls low and holds for a minimum 150ms after the voltage returns above the threshold.
The MAX6366PKA46+T is ROHS3 compliant. For additional documentation such as REACH or conflict minerals reports, contact the distributor or manufacturer — this listing confirms ROHS3 status only.
Within the MAX6366 family, the threshold voltage is the key differentiator — variants with different thresholds (e.g., 2.63V, 3.08V, 4.38V) share the same SOT-23-8 pinout and reset timing. For a 5V rail, this 4.63V version is the standard choice; a 4.38V variant offers a slightly lower trip point if the supply has more droop.
