µP Reset Circuits with Long Manual Reset  
Setup Period  
General Description  
Features  
The MAX6443–MAX6452 low-current microprocessor  
reset circuits feature single or dual manual reset inputs  
with an extended 6.72s setup period. Because of the  
extended setup period, short switch closures (nuisance  
resets) are ignored.  
Single- or Dual-Supply Voltage Monitors  
Precision Factory-Set Reset Thresholds from  
1.6V to 4.6V  
Adjustable Threshold to Monitor Voltages Down  
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 of 6.72s.  
These devices ignore manual reset transitions of less  
than 6.72s (typ).  
to 0.63V (MAX6449–MAX6452)  
Single or Dual Manual Reset Inputs with Extended  
6.72s Setup Period  
Optional Short Setup Time Manual Reset Input  
(MAX6447/MAX6448 and MAX6451/MAX6452)  
Immune to Short Voltage Transients  
Low 6µA Supply Current  
Guaranteed Valid Reset Down to V  
= 1.0V  
CC  
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.  
Active-Low RESET (Push-Pull or Open-Drain)  
Outputs  
140ms (min) Reset Timeout Period  
Small SOT143 and SOT23 Packages  
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.

The MAX6443–MAX6452 have an active-low RESET  
with push-pull or open-drain output logic options. These  
devices, offered in small SOT packages, are fully guar-  
anteed over the extended temperature range (-40°C to  
+85°C).  
Note: The “_ _ ” is a placeholder for the threshold voltage level  
of the devices. A desired threshold level is set by the two-num-  
ber suffix found in Table 1. All devices are available in tape-  
and-reel only. There is a 2500-piece minimum order increment  
for standard versions (Table 2). Sample stock is typically held  
on standard versions only. Nonstandard versions require a  
minimum order increment of 10,000 pieces. Contact factory for  
availability.  
Applications

DVD Players  
Devices are available in both leaded and lead-free packaging.  
Specify lead-free by replacing “-T” with “+T” when ordering.
