The ADM1169 Super Sequencer® 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 ADM1169 integrates a 12-bit ADC and four 8-bit voltage output DACs. These circuits can be used to implement a closed-loop margining system that enables supply adjustment by altering either the feedback node or reference of a dc-to-dc converter using the DAC outputs.
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 board functionality at -5% of nominal supplies), or it 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 undervoltage faults, overvoltage faults, or out-ofwindow faults on up to eight supplies. In addition, there are eight programmable outputs that can be used as logic enables. Six of these programmable outputs can also provide up to a 12 V output for driving the gate of an N-FET that can be placed in the path of a supply.
The logical core of the device is a sequencing engine (SE). 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.
A block of nonvolatile EEPROM is available that can be used to store user-defined information and may also be used to hold a number of fault records that are written by the sequencing engine defined by the user when a particular fault or sequence occurs.
The ADM1169 is controlled via configuration data that can be programmed into an EEPROM. The entire configuration can be programmed using an intuitive GUI-based software package provided by Analog Devices, Inc.

Requires the ADMxxxx Common Run-time to be installed in order to provide driver support for the USB-SMBUS-CABLEZ and USB-SDP-CABLEZ interface connectors. If there are previous versions of this software (v4.0.6 or earlier), or the ADM1175-7 & ADM1191-92 software (v3.0.1 or earlier) installed they should be removed prior to installing the common run-time.
ADMxxxx Common Run-Time
This run-time installer is shared between the SuperSequencer, ADM1175-92 and ADM1293/4 and the Hot Swap and Power Monitor tools. Contains driver support for the USB-SMBUS-CABLEZ and USB-SDP-CABLEZ interface connectors.
