    LTC®4231 是一款微功率热插拔 (Hot Swap) 控制器,其允许在工作中的电源上安全地进行电路板的插拔操作。一个内部高压侧开关驱动器负责控制一个外部 N 沟道 MOSFET。背对背 MOSFET 可用于提供低至–40V 的反向电源保护。

    LTC4231 可提供一个防反跳延迟并允许 GATE 以一种可调速率斜坡上升。在启动之后,LTC4231 的静态电流在正常操作期间 (输出处于运行状态) 下降至 4μA。UVL、UVH、OV 和 GNDSW 周期性地监察过压和欠压情况,并将总静态电流保持在低水平。把 SHDN 拉至低电平可关断 LTC4231,此时静态电流减小至 0.3μA。

    在过流故障期间,LTC4231 在运行一个可调定时器的同时主动地限制电流。LTC4231-1 在电流故障之后保持关断状态,而 LTC4231-2 则在一个冷却周期之后自动重新施加电源。



    应用
