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
