GENERAL DESCRIPTION  
The ADM1085/ADM1086/ADM1087/ADM1088 are simple  
sequencing circuits that provide a time delay between the  
enabling of voltage regulators and/or dc-dc converters at power-  
up in multiple supply systems. When the output voltage of the  
first power module reaches a preset threshold, a time delay is  
initiated before an enable signal allows subsequent regulators to  
power up. Any number of these devices can be cascaded with  
regulators to allow sequencing of multiple power supplies.  
All four models have a dedicated enable input pin that allows  
the output signal to the regulator to be controlled externally.  
This is an active high input (ENIN) for the ADM1085 and  
ADM1086, and an active low input (  
) for the ADM1087  
ENIN  
and ADM1088.  
The Simple Sequencers are specified over the extended  
−40°C to +125°C temperature range. With low current  
consumption of 15 μA (typical) and 6-lead SC70 packaging,  
the parts are suitable for low-power portable applications.  
Threshold levels can be set with a pair of external resistors in a  
voltage divider configuration. With appropriate resistor values,  
the threshold can be adjusted to monitor voltages as low as 0.6 V.

different regulators and converters.
