DESCRIPTION
The DS1814 5-Volt MicroMonitor and the DS1819 3.3V MicroMonitor monitor three vital conditions for
a microprocessor: power supply, software execution, and external override. First, a precision temperature-
compensated reference and comparator circuit monitor the status of V CC . When an out-of-tolerance
condition occurs, an internal power-fail signal is generated which forces the reset(s) to an active state.
When V CC returns to an in-tolerance condition, the reset signal is kept in the active state for a minimum of
140ms to allow the power supply and processor to stabilize.
