... Industrial temperature range -40°C to +85°C 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 V protection. When the sense input detects an out-of-tolerance condition a non-maskable interrupt is generated ...
