DESCRIPTION  
The DS1232LP/LPS Low Power MicroMonitor Chip monitors three vital conditions for a  
microprocessor: power supply, software execution, and external over-ride. 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.
