RESET
Reset Output, Open-Drain or Push-Pull, Active-Low.
RESET
changes from HIGH to LOW when V
CC
drops below the
selected reset threshold or
MR
is pulled low.
RESET
remains
LOW for the reset timeout period after V
CC
exceeds the device
reset threshold and
MR
is released high.

MR
Active-Low Manual Reset Input. Internal 20k
pullup to V

.
Pull LOW to force a reset. Reset remains active as long as
MR
is
LOW and for the reset timeout period after
MR
goes HIGH.
Leave unconnected or connect to V

RESET-IN
Adjustable Reset Threshold Input. High-impedance input for reset comparator. Connect
this pin to an external resistive-divider network to set the reset threshold voltage; the
typical threshold is 444mV. Reset is asserted when RESET-IN is below the threshold (V
CC
is not monitored).
