DESCRIPTION  
The DS1232 MicroMonitor Chip monitors three vital conditions for a microprocessor: power supply,  
software execution, and external override. First, a precision temperature-compensated reference and  
comparator circuit monitors the status of VCC. When an out-of-tolerance condition occurs, an internal  
power fail signal is generated which forces reset to the active state. When VCC returns to an in-tolerance  
condition, the reset signals are kept in the active state for a minimum of 250 ms to allow the power supply  
and processor to stabilize.
