NAME
FUNCTION
1—
—
Push-Pull (MAX6841) or Open-Drain (MAX6842) Active-Low Reset Output.
RESET
changes from high to low when VCC drops below the selected reset threshold or
MR is pulled low. RESET remains low for the reset timeout period after VCC
exceeds the device reset threshold and
MR is released high.

RESET
Push-Pull (MAX6843) or Open-Drain (MAX6845) Active-Low Reset Output.
RESET
changes from high to low when RESET IN drops below the 187.4mV reset
threshold (referenced to VCC) or MR is pulled low. RESET remains low for the
reset timeout period after RESET IN exceeds the reset threshold and
MR is
released high.

Push-Pull Active-High Reset Output. RESET changes from low to high when VCC
input drops below the selected reset threshold or
MR is pulled low. RESET
remains high for the reset timeout period after VCC exceeds the device reset
threshold and
MR is released high.

RESET
Push-Pull Active-High Reset Output. RESET changes from low to high when the
RESET IN input drops below the 187.4mV reset threshold (referenced to VCC).
RESET remains high for the reset timeout period after RESET IN exceeds the reset
threshold.

RESET IN
Adjustable Reset 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 187.4mV (referenced to VCC). The MAX6843/MAX6844/
MAX6845 assert a reset signal when the VCC to RESET IN differential falls below
its threshold voltage.

MR
Active-Low Manual Reset Input. Internal 20k
pullup to VCC. 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 VCC if unused.
55
5
VCC
Supply Voltage. Monitored supply for the MAX6841/MAX6842.
