DESCRIPTION

The DS1705/DS1706 3.3- or 5.0-Volt MicroMonitor monitors three vital conditions for a microprocessor:

power supply, software execution, and external override. A precision temperature compensated reference

and comparator circuit monitor the status of V_CCat 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
