ADM1066 General Description

The ADM1066 is a configurable supervisory/sequencing device that offers a single-chip solution for supply monitoring and sequencing in multiple supply systems. In addition to these functions, the ADM1066 integrates a 12-bit ADC and six 8-bit voltage output DACs. These circuits can be used to implement a
closed-loop margining system, which enables supply adjustment by altering either the feedback node or reference of a dc/dc converter using the DAC outputs.

Supply margining can be performed with a minimum of external components. The margining loop can be used for incircuit testing of a board duringproduction (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/dc converter. The device also provides up to ten programmable inputs for monitoring under, over, or out-of-window faults on up to ten supplies. In addition, ten 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 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 ADI.
