DESCRIPTION

The DS1818 EconoReset uses a precision temperature-compensated 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_CCreturns 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 DS1818 also monitors a pushbutton on the reset output. If the reset line is pulled low, a reset is

generated upon release and the DS1818 output will be held in reset output low for typically 150 ms.
