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.
