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.
Note: Some revisions of this device may incorporate deviations from published specifications known as errata. Multiple revisions of any
device may be simultaneously available through various sales channels. For information about device errata, click here: http://dbserv.maxim-
