RESET

Active-Low Push-Pull Reset Output. RESET changes from high to

low when V

drops below the detector threshold (V

) or MR is

pulled low. RESET remains low for the reset timeout period after V

exceeds V

and MR is high. When MR is low, RESET is low.

Active-High Push-Pull Reset Output. RESET changes from low to

high when V

drops below the detector threshold (V

) or MR is

pulled low. RESET remains high for the reset timeout period after V

exceeds V

and MR is high. When MR is low, RESET is high.

RESET

Active-Low Open-Drain Reset Output. RESET changes from high-

impedance to active-low when V

drops below the detector thresh-

old (V

) or MR is pulled low. RESET remains low for the reset timeout

period after V

exceeds the reset threshold and MR is high. When

MR is low, RESET is low.

Active-Low Manual-Reset Input. Drive low to force a reset. Reset

remains active as long as MR is low and for the reset timeout period (if

applicable) after MR is driven high. MR has an internal pullup resistor

connected to V

CC,

and may be left unconnected if not used.
