• Manufacturer Part Number: adm1069ast-reel
• Description: Super Sequencer With Margining Control
• Manufacturer: Analog Devices, Inc.

GENERAL DESCRIPTION
(continued from Page 1)
Supply margining can be performed with a minimum of
external components. The margining loop can be used for in-
circuit testing of a board during production (for example, to
verify the board’s functionality at −5% of nominal supplies),
or can be used dynamically to accurately control the output
voltage of a dc-to-dc converter.
The device also provides up to eight programmable inputs for
monitoring under, over, or out-of-window faults up to eight
supplies. In addition, eight programmable outputs can be used
as logic enables. Six of them can also provide up to a 12 V
output for driving the gate of an N-channel FET, which can be
placed in the path of a supply.

The logical core of the device is a sequencing engine. This state-
machine-based construction provides up to 63 different states.
This design enables very flexible sequencing of the outputs,
based on the condition of the inputs.
The ADM1069 is controlled via configuration data that can be
programmed into an EEPROM. The whole configuration can
be programmed using an intuitive GUI-based software package
provided by Analog Devices, Inc.
