The is an EconoReset Supervisory Circuit with pushbutton. The DS1818 EconoReset uses a precision temperature-compensated reference and comparator circuit to monitor the status of the power supply VCC. When an out-of-tolerance condition is detected, an internal power-fail signal is generated which forces reset to the active state. When VCC 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 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 150ms.
