3 / 32 page ADM1067 Rev. B | Page 3 of 32 GENERAL DESCRIPTION (continued from Page 1) Supply margining can be performed with a minimum of external components. The margining capability can be used for in-circuit testing of a board during production (for example, to verify the board functionality at −5% of nominal supplies). It can also be used dynamically to accurately control the output voltage of a dc-to-dc converter. The device provides up to 10 programmable inputs for monitoring under, over, or out-of-window faults on up to 10 supplies. In addition, 10 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 that 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 device 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.
