ADI公司的ADM1266是具有具裕量控制和故障记录功能的可级联超级时序控制器,适用于多达 17个电源的完整监控和排序解决方案,通过专用的二线接口,多达16个ADM1266 IC可以扩展到 257个电源,具有完全可编程的排序引擎,可实现电源的实时监控, 可兼容行业标准 PMBus 接口.主要用在通信基础设备和工业测试与测量.本文介绍了ADM1266主要特性,功能框图和详细框图,以及评估板ADM1266-EVALZ主要特性,主要元件分布和电路图,材料清单和PCB丝印图.

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 (DAC..
