*DS1834D Active High Reset

DESCRIPTION

The DS1834 Dual EconoResets monitors three vital system conditions: 5-volt supply, 3.3-volt supply,

and an external override. First a precision temperature reference and comparator circuit monitor the status

of the 5-volt supply and the 3.3-volt supply. When an out-of-tolerance condition is detected, an internal

power-fail signal is generated which forces the reset of the affected supply to an active state.

Lastly, the DS1834 supports an external reset via an internally debounced pushbutton input. When the

pushbutton is pulled low both resets will be asserted for approximately 350 ms after the pushbutton is

released.
