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

●Provide programmable time delays between enable signals

●Can be cascadedwith power modules for multiple supply sequencing

●Power supply monitoring from 0.6 V Output stages:

●   High voltage (up to 22 V) open-drain output (ADM1085/ADM1087)

●   Push-pull output (ADM1086/ADM1088)

●Capacitor-adjustable time delays

●High voltage (up to 22 V) Enable and VINinputs
