General Description  
Features  
♦ Precision Factory-Set Reset Thresholds From  
The MAX6453–MAX6456 are low-power, dual-voltage  
µP supervisors featuring separate V  
reset and manu-

1.6V to 4.6V  
al reset outputs. The dual outputs support both soft-  
system reset (interrupt) and hard-system reset (reboot)  
functions. The reset output asserts when any of the  
monitored voltages falls below its specified threshold  
and remains asserted for the reset timeout (140ms min)  
after all voltages exceed their respective reset thresh-  
olds. All devices are offered with nine factory-fixed  
reset thresholds for monitoring primary system voltages  
♦ Adjustable Threshold to Monitor Voltages Down  
to 0.63V  
♦ Manual Reset Input with Extended 3.36s Setup  
Period  
♦ Immune to Short Voltage Transients  
♦ Low 6µA Supply Current  
(V ) from 1.8V to 5V and an adjustable reset input for  
CC  
monitoring a secondary system voltage down to 0.63V.  
♦ Guaranteed Valid Reset Down to V  
= 1.0V

Each device has a manual reset input, a V  
reset out-

♦ Active-Low RESET (Push-Pull or Open-Drain)  
put, and a manual reset output. The MAX6453/  
MAX6454 manual reset output asserts when the manual  
reset input is low. It remains asserted for the manual  
reset timeout period (140ms min) after the manual reset  
input transitions high. The MAX6453/MAX6354 manual  
reset input controls only the manual reset output and

the manual reset input is low for less than 3.3s (typ), only  
the manual reset output asserts and remains asserted for  
the manual reset timeout period (140ms min) after the  
manual reset input transitions high. If the manual reset  
input is low for at least 3.3s (typ), the reset output also  
asserts and remains asserted for the reset timeout peri-  
od (140ms min) after the manual reset input transitions  
high. This enhanced feature allows the implementation of  
a soft/hard-system reset combination.  
Note: The “_” is a placeholder for the threshold voltage level of  
the devices. A desired threshold level is set by the part 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.  
The MAX6453/MAX6455 have active-low push-pull  
reset and manual reset outputs, and the MAX6454/  
MAX6456 have active-low open-drain reset and manual  
reset outputs. All devices are available in small SOT23-  
6 packages and are fully specified over the extended  
temperature range (-40°C to +85°C).  
Devices are available in both leaded and lead-free packaging.  
Specify lead-free by replacing “-T” with “+T” when ordering.
