GENERAL DESCRIPTION  
The parts are highly reliable with accurate voltage references  
and immunity to fast, negative-going transients on VCC. Low  
current consumption and space-efficient 4-lead SC70 packaging  
make the ADM6711/ADM6713 ideal for use in low power  
portable applications.  
The ADM6711/ADM6713 are reset generator circuits suitable  
for use in microprocessor based systems. They provide a reset  
signal on power-up, power-down, and whenever the supply volt-  
age falls below a preset threshold. In addition, both parts have a  
debounced manual reset input so that a reset signal can also be  
initiated with an external switch or logic signal.

CC  
With six different reset threshold options available ranging from  
2.32 V to 4.63 V, the ADM6711/ADM6713 are suitable for  
monitoring 2.5 V, 3 V, 3.3 V, and 5 V supplies. A reset timeout  
of at least 140 ms occurs when VCC rises above the threshold.  
This gives the supply voltage time to stabilize before the micro-  
processor starts up.

The ADM6711 has a push-pull output, so no additional external  
components are needed. The ADM6713’s open-drain output  
requires an external pull-up resistor, which can be connected to a  
voltage higher than VCC, if desired.
