Typical Operating Characteristics (continued)
Push-Pull (MAX6841) or Open-Drain (MAX6842) Active-Low Reset Output. RESET
changes from high to low when V
MR is pulled low. RESET remains low for the reset timeout period after V
exceeds the device reset threshold and MR is released high.
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 V
reset timeout period after RESET IN exceeds the reset threshold and MR is
released high.
Ground
Push-Pull Active-High Reset Output. RESET changes from low to high when V
input drops below the selected reset threshold or MR is pulled low. RESET
remains high for the reset timeout period after V
threshold and MR is released high.
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 V
RESET remains high for the reset timeout period after RESET IN exceeds the reset
threshold.
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 V
MAX6845 assert a reset signal when the V

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