DESCRIPTION
The DS1813 EconoReset uses a precision temperature reference and comparator circuit to monitor the
status of the power supply (V
CC
). When an out-of-tolerance condition is detected, an internal power-fail
signal is generated which forces reset to the active state. When V
CC
returns to an in-tolerance condition,
the reset signal is kept in the active state for approximately 150 ms 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 150 ms.
