GENERAL DESCRIPTION
The DS1813 EconoReset uses a precision
temperature reference and comparator circuit to
monitor the status of the power supply (V
When an out-of-tolerance condition is detected,
an internal power-fail signal is generated which
forces reset to the active state. When V
to an in-tolerance condition, the reset signal is
kept in the active state for approximately 150ms
to allow the power supply and processor to
stabilize.
The DS1813 also monitors a pushbutton on the
reset output. If the reset line is pulled low, a reset
is generated upon release and will be held in reset
output low for typically 150ms.
