The DS1817 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 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.
