只需用极少的外部元件便可执行电源余量微调。余量微调环路可以用于生产期间的电路板在线测试(例如,验证电路板在电源电压比标称电压低5%时的功能),也可以动态使用,以便精确控制DC-DC转换器的输出电压。
该器件还提供多达10路可编程输入,最多可监控10个电源的欠压故障、过压故障或窗口外故障。此外,10路可编程输出可用作逻辑使能。其中6路可编程输出也可以提供最高12 V输出,用于驱动可置于电源路径的N-FET栅极。
利用ADM1062可以进行温度测量。它含有一个内部温度传感器,还有一路差分输入用于远程热敏二极管,二者均通过12位ADC进行测量。
该器件的逻辑内核是一个时序控制引擎。它采用状态机结构,可提供多达63种不同状态。这种设计可以根据输入状况,对输出进行灵活的时序控制。
ADM1062通过编程写入EEPROM中的配置数据进行控制。全部配置可以利用ADI公司具有直观图形用户界面(GUI)的软件包进行编程。
