NAME
FUNCTION
5———————
RST2
Active-Low Reset Output,
Open-Drain or Push-Pull.
RST2 changes from high
to low when V
CC
1 or
V
CC
2 drops below the
selected reset thresholds
or MR is pulled low. RST2
remains low for the reset
timeout period after
V
CC
1/V
CC
2 exceed the
device reset thresholds
or MR goes low to high.
Open-drain outputs
require an external pullup
resistor. Push-pull
outputs are referenced to
V
CC
2.

MR
Active-Low Manual Reset
Input. Internal 50kΩ
pullup to V
CC
1. 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
CC
1 if unused.

Secondary Supply
Voltage Input. Powers the
device when it is above
V
CC
1 and input for
secondary reset
threshold monitor.

V
CC
1
Primary Supply Voltage
Input. Powers the device
when it is above V
CC
2
and input for primary
reset threshold monitor.
