This is a stress rating only and functional operation of the device at these or any other conditions above those indicated in the operation sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods of time may affect reliability.

The DS1812 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.
