RESET
Reset Output, Push-Pull or Open Drain Active Low.
RESET
changes from high to low when any monitored power-supply
input (V
CC
1, V
CC
2, RSTIN) drops below its selected reset
threshold. It remains low until all monitored power-supply
inputs exceed their selected reset thresholds for the V
CC
reset timeout period.
RESET
is forced low if
MR
is low for at
least the
MR
minimum input pulse width. It remains low for
the
MR
reset timeout period after
MR
goes high. The push-
pull output is referenced to V
CC
1. The MAX6736/MAX6738
open-drain outputs require an external pullup resistor. The
MAX6740/MAX6741/MAX6742 open-drain outputs have an
internal 50k
pullup resistor to V
CC
1 and provide a manual
reset function.
Ground
Manual Reset, Active Low. Pull low for at least
MR
minimum
input pulse width to force
RESET
low. Reset remains active
as long as
MR
is low and for the
MR
reset timeout period
after
MR
goes high. There is an internal 1.5k
pullup resistor
to V
CC
1.

RSTIN
Adjustable Reset Threshold Input.
RESET
is asserted when
RSTIN is below the internal 0.488V reference level. Set the
adjustable reset threshold with an external resistor-divider
network. Connect RSTIN to V
CC
1 if unused.

PFI
Power-Fail Comparator Input.
PFO
is asserted when PFI is
below 0.488V.
PFO
is deasserted without any reset timeout
period when PFI goes above 0.488V. Connect PFI to an
external resistor network to set the desired monitor
threshold.

Power-Fail Comparator Output, Open Drain Active Low.
PFO

POK1
V
CC
1 Power-OK Output, Open Drain Active High. POK1
remains low as long as V
CC
1 is below V
TH
1.
POK1 output
goes high after V
CC
1 exceeds V
TH
1 for the POK1 timeout
period. POK1 logic is independent of the
MR
or V
CC
2 inputs.
The output can be used to control V
CC
1-to-V
CC
2 supply
sequencing.
