Description

The ADM1266 Super Sequencer? is a configurable supervisory/sequencing device that offers a single-chip solution for supply monitoring and sequencing in systems with up to 17 supplies.?For systems with more supplies (up to 257), the operation of up?to 16 ADM1266 devices can be synchronized through a proprietary?2-wire interface (interdevice bus). The sequencing engine (SE) monitors the supply fault detectors?(SFDs), programmable driver input/outputs (PDIOs), general-purpose?inputs/outputs (GPIOs), and timers, and controls the?PDIOs and GPIOs to sequence the supplies up and down as?required. The logical core of the device is an ARM? Cortex-M3?microcontroller. The firmware is supplied by Analog Devices,?Inc., and all configuration is performed through an intuitive?graphic user interface (GUI). Additionally, the ADM1266 integrates an analog-to-digital?converter (ADC) and voltage output digital-to-analog converters?(DACs) that can be used to adjust either the feedback node or?reference of a dc-to-dc converter to implement a closed-loop,?autonomous, margining system.A block of nonvolatile EEPROM is available to record voltage,?time, and fault information when instructed to by the sequencing?engine configuration.APPLICATIONS Communications infrastructure Industrial test and measurement
