DESCRIPTION
The DS1817 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.
