双/三电压、电源排序器/监控器

MAX6880–MAX6883双/三电压监控器设计用于上电时对电源进行排序。当所有电压超过各自门限后，这些器件依次接通系统电压，导通n沟道MOSFET作为开关使用。排序电压之间的时间间隔由外部电容决定，实现灵活的延时定时。MAX6880/MAX6881可排序三路电压，MAX6882/MAX6883可排序两路电压。\n启动后，这些器件监视所有电压，当所有电压达到其容限后，内部电荷泵顺序导通外部n沟道MOSFET，为系统加载电压。内部电荷泵驱动栅极电压比相应的输入电压高5V，从而可确保MOSFET完全打开导通并降低导通电阻。\nMAX6880–MAX6883具有电容可调的摆率控制功能，实现受控的接 ·电容可调的上电排序延时\n·内部电荷泵导通外部n沟道FET\n·电容可调的电源就绪输出超时周期(MAX6880/MAX6882)\n·可调欠压锁定或者逻辑使能输入\n·每通道输出部具有100Ω下拉，可对容性负载迅速放电\n·0.5V至5.5V额定IN_/OUT_范围\n·2.7V至5.5V工作电压范围\n·不受短路电压瞬变的影响\n·小型、4mm x 4mm、 24引脚或者16引脚薄型QFN封装;
