DS1831/A/B  
3.3V reset or for all reset outputs by the master pushbutton. The DS1831A replaces one reference  
comparator and the master pushbutton with watchdog and the DS1831B replaces the 3.3V PBRST with a  
last reset status output.  
TOL and TD inputs allow user configuration of the DS1831 for multiple applications. The TOL inputs  
configure the tolerance for the specified output and the TD inputs configure the reset time delays.
