The ADM1260 Super Sequencer® is a configurable supervisory/sequencing device that offers a single-chip solution for supply monitoring and sequencing in multiple supply systems.
A high speed interchip bus (ICB) allows multiple devices to be easily linked together. It is possible to create a system capable of sequencing up to 40 supplies and monitoring up to 37 supplies. Using the ADI Power Studio™ software, the operation of the ICB is transparent to the user, making multiple devices appear to operate as a single virtual sequencer.
In addition to these functions, the ADM1260 integrates a 12-bit analog-to-digital converter (ADC) and six 8-bit voltage output digital-to-analog converters (DACs). Use the ADC and the DACs to implement a closed-loop margining system that enables supply adjustment by altering either the feedback node or the 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 10 programmable inputs for monitoring undervoltage faults, overvoltage faults, or out of window faults on up to 10 supplies. In addition, 10 programmable outputs can be used as logic enables. Six of these programmable outputs can also provide an output of up to 12 V 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 61 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 can also be used to hold a number of fault records that are written by the sequencing engine, as defined by the user when a particular fault or sequence occurs.
The device is controlled via configuration data that can be programmed into an EEPROM. The entire configuration can be programmed using an intuitive graphical user interface (GUI)-based software package provided by Analog Devices, Inc., the ADI Power Studio software.
