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

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.
