GENERAL DESCRIPTION
The ADM1085/ADM1086/ADM1087/ADM1088 are simple sequencing circuits that provide a time delay between the enabling of voltage regulators and/ordc-dc converters atpower upin multiple supply systems. When the output voltage of the first power module reaches a preset threshold,atime delayis initiated before an enable signal allows subsequent regulators to power up. Any number ofthese devices can be cascaded with regulators toallow sequencing ofmultiple power supplies.
FEATURES
