DS1813

The DS1813 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.

The DS1813 also monitors a pushbutton on the reset output. If the reset line is pulled low, a reset is generated upon release and will be held in reset output low for typically 150 ms.
