DESCRIPTION

The DS1814 5-Volt MicroMonitor and the DS1819 3.3-Volt 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_CCreturns to an in-tolerance condition, the reset signal is kept in the active state for a

minimum of 140 ms to allow the power supply and processor to stabilize.
