MAX6443–MAX6452  
µP Reset Circuits with Long Manual Reset  
Setup Period  
General Description  
Features  
● Single or Dual-Supply Voltage Monitors  
The MAX6443–MAX6452 low-current microprocessor  
reset circuits feature single or dual manual reset inputs  
with an extended setup period. Because of the extended  
setup period, short switch closures (nuisance resets) are  
ignored.  
● Precision Factory-Set Reset Thresholds from  
1.6V to 4.6V  
● Adjustable Threshold to Monitor Voltages Down to  
0.63V (MAX6449–MAX6452)  
● Single or Dual Manual Reset Inputs with Extended  
Setup Period  
● Optional Short Setup Time Manual Reset Input  
(MAX6447/MAX6448 and MAX6451/MAX6452)  
● Immune to Short Voltage Transients  
● Low 6µA Supply Current  
On all devices, the reset output asserts when any of  
the monitored supply voltages drops below its specified  
threshold. The reset output remains asserted for the reset  
timeout period (210ms typ) after all monitored supplies  
exceed their reset thresholds. The reset output is one-  
shot pulse asserted for the reset timeout period (140ms  
min) when selected manual reset input(s) are held low for  
an extended setup timeout period. These devices ignore  
manual reset transitions of less than the extended setup  
timeout period.  
● Guaranteed Valid Reset Down to V  
= 1.0V  
CC  
● Active-Low RESET (Push-Pull or Open-Drain)  
Outputs  
● 140ms (min) Reset Timeout Period  
● Small SOT143 and SOT23 Packages  
● AEC-Q100 Qualified (MAX6444US16K/V+T)  
The MAX6443–MAX6448 are single fixed-voltage µP  
supervisors. The MAX6443/MAX6444 have a single  
extended manual reset input. The MAX6445/MAX6446  
have two extended manual reset inputs. The MAX6447/  
MAX6448 have one extended and one immediate manual  
reset input.  
Ordering Information at end of data sheet.  
The MAX6449–MAX6452 have one fixed-threshold µP  
supervisor and one adjustable-threshold µP supervisor.  
The MAX6449/MAX6450 have two delayed manual reset  
inputs. The MAX6451/MAX6452 have one delayed and  
one immediate manual reset input.  
Typical Operating Circuit  
+3.3V  
The MAX6443–MAX6452 have an active-low RESET with  
push-pull or open-drain output logic options. These devic-  
es, offered in small SOT packages, are fully guaranteed  
over the extended temperature range (-40°C to +85°C).
