  • ADM12914- ±0.8%精度、四通道UV/OV正/负电压监控器
    ADM12914: ±0.8%精度、四通道UV/OV正/负电压监控器

    ADM12914是一款四通道电压监控器IC，提供业界领先的±0.8%阈值精度，非常适合监控各种应用中的多个供电轨。每个受监控的供电轨均有两个专用输入引脚VHx和VLx，利用这些引脚可以监控每个供电轨是否发生过压(OV)及欠压(UV)状况。所有受监控的供电轨均共用一个通用欠压(/UV)输出引脚和一个通用过压(/OV)输出引脚。

    ADM12914含有一路1 V缓冲基准电压输出REF；当监控负电压时，它可充当偏置电压。三态SEL引脚决定第三路和第四路输入的极性，即通过引脚配置该器件来监控正电源或负电源。

    该器件内置分流稳压器，因而可以用于电压较高的系统。此特性要求在主供电轨与VCC引脚之间放置一个电阻，用来限制流入VCC引脚的电流，使之不超过10 mA。ADM12914使用内部分流稳压器来调节VCC， MoreRead more
