NAME

FUNCTION

1—

Active-Low Push-Pull or Open-Drain Output. RESET changes from high to low when

140ms (min) reset timeout period after all monitored power-supply inputs exceed their

selected reset thresholds. MR does not affect RESET output. For open-drain outputs,

connect to an external pullup resistor.

RESET

Active-Low Push-Pull or Open-Drain Output. RESET changes from high to low when

140ms (min) reset timeout period after all monitored power-supply inputs exceed their

selected reset thresholds. RESET changes from high to low after MR input is held low

for the extended (typ) setup timeout period and deasserts 140ms (min) after MR

deasserts. For open-drain outputs, connect to an external pullup resistor.

MROUT

Manual Reset Push-Pull or Open-Drain Output. MROUT asserts immediately after MR is

pulled low. MROUT remains low for 140ms (min) after MR is deasserted. For open-

drain outputs, connect to an external pullup resistor.

RSTIN

Reset Input. High-impedance input to the adjustable reset comparator. Connect RSTIN

to the center point of an external resistor divider to set the threshold of the externally

monitored voltage.
