DESCRIPTION  
The DS1836 MicroManager performs three vital system functions. First a precision temperature-  
compensated reference and comparator circuit monitor the status of the voltage on VCC and when an out-  
of-tolerance condition is detected, an internal power-fail signal is generated which forces the reset active.  
If VCC continues to degrade it switches to the battery supply when VCC drops below 3.8 volts (2.6 volts  
for 3.3-volt versions). When VCC exceeds 3.9 volts (2.8 volts for 3.3-volt versions); VOUT will again be  
supplied from VCC. Reset will remain active for 350 ms after VCC returns to an in-tolerance condition.  
Lastly, the DS1836 supports a sense input that sends a non-maskable interrupt whenever the sense input  
drops below 1.25 volts.
