The output is open-drain or open-collector, requiring an external pull-up resistor to the logic supply. The reset timeout is 90ms minimum — the supervisor holds the reset line low for at least this duration after VCC rises above the threshold, ensuring downstream devices complete their power-up sequence before the system starts executing code. The threshold is adjustable/selectable via an external resistor divider. ## Industrial temperature range and compact footprint Housed in a 5-pin SOT-23-5 package, the footprint suits multi-rail boards where a supervisor per rail is needed. ## Active production — sourcing per RFQ Analog Devices has not announced a discontinuance or last-time-buy window for this order code. The part is ROHS3 compliant.","metaTitle":"MAX6457UKD3C+T Simple Reset/Power-On Reset Supervisor","metaDescription":"MAX6457UKD3C+T from Analog Devices — Active-low open-drain output, 90ms min reset timeout, adjustable threshold, -40°C to 125°C.
