LTC4366 - 高电压浪涌抑制器
LTC®4366 浪涌抑制器可保护负载免遭高压瞬变的损坏。通过控制一个外部 N 沟道 MOSFET 的栅极，LTC4366 可在过压瞬变过程中调节输出。在 MOSFET 两端承载过压的情况下，负载可以保持运作状态。在返回线路中布设一个电阻器可隔离 LTC4366，并允许其随电源向上浮动；因此，输出电压的上限仅取决于高值电阻器的可用性和 MOSFET 的额定规格。
一个可调的过压定时器能在浪涌期间避免损坏 MOSFET，而一个附加的 9 秒定时器则为 MOSFET 提供了冷却周期。停机引脚负责在停机期间将静态电流减小至 14μA 以下。在一个故障发生之后，LTC4366-1 将锁断，而 LTC4366-2 则将执行自动重试操作。
