DESCRIPTION
The DS1830 Reset Sequencer monitors the power supply for an in-tolerance condition and the pushbutton
reset input for a manual reset. First a precision temperature-compensated reference and comparator circuit
monitors the status of the power supply and when an out-of-tolerance condition is detected, an internal
power fail signal is generated that forces the reset lines to go to an active state. If the power supply
returns to an in-tolerance condition,
RST1
will release followed by
RST2
and finally
RST3
. Sequencing of
resets allows for systems to power-up in an orderly manner providing superior reliability.
