集成PMBus接口的热插拔控制器和数字电源及电能监控器

ADM1276是一款热插拔控制器，允许将电路板插入带电背板或从带电背板移除。该器件还集成12位模数转换器(ADC)，可通过PMBus™接口进行电流和电压回读。\n\n 负载电流利用内部电流检测放大器测量，通过SENSE+引脚和SENSE-引脚测量电源路径内检测电阻两端的电压。默认限值设置为20 mV，如果需要，可通过内部基准电压源至ISET引脚的电阻分压器网络对该限值进行调整。\n\n ADM1276通过GATE引脚控制电源路径内外部N沟道FET的栅极电压，从而限制流经检测电阻的电流，检测电压（因而负载电流）维持在预设最大值以下。ADM1276通过限制FET保持开启（电流处 • 可控制2 V至20 V范围内的电源电压\n\n• 短路响应时间：370 ns \n\n• 通过电阻编程在5 mV至25 mV进行电流限制 \n\n• 精度达到±1%，支持通过12位ADC进行电流、VIN/VOUT回读\n\n• 电荷泵式栅极驱动多个外部N沟道FET\n\n• 高栅极驱动电压确保实现最低RDSON\n\n• 利用折返实现更严密的FET SOA保护\n\n• 可对电流默认值执行自动重试或锁定\n\n• 符合SOA的可编程限流定时器 \n\n• 欲了解更多特性，请参考数据手册;
