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 130ms to allow the power supply and processor to stabilize.

Key Features
  • Holds microprocessor in check during power transients
  • Automatically restarts microprocessor after power failure
  • Monitors pushbutton for external override
  • Accurate 5%, 10% or 20% resets for 3.3V systems and 5% or 10% resets for 5.0V systems
  • Eliminates the need for discrete components
  • 20% tolerance compatible with 3.0V systems
  • Pin compatible with the MAXIM MAX707/MAX708 in 8-pin DIP, 8-pin SO packages
  • 8-pin DIP, 8-pin and µSOP SO and 8-pin µSOP packages available
  • Industrial temperature range -40°C to +85°C
