DESCRIPTION  
The DS1707/DS1708 3.3- or 5.0-Volt MicroMonitor monitors three vital conditions for a microprocessor:  
power supply, voltage sense, and external override. A precision temperature-compensated reference and  
comparator circuit monitor the status of VCC at the device and at an upstream point for maximum  
protection. When the sense input detects an out-of-tolerance condition a non-maskable interrupt is  
generated. As the voltage at the device degrades an internal power fail signal is generated which forces  
the reset to an active state. When VCC returns to an in-tolerance condition, the reset signal is kept in the  
active state for a minimum of 130 ms to allow the power supply and processor to stabilize.
