LTC4364 - 具理想二极管的浪涌抑制器
LTC®4364 浪涌抑制器具有理想二极管控制器，可保护负载免遭高电压瞬变的损坏。通过控制一个外部 N 沟道 MOSFET 传输器件两端的电压降，该器件可在过压过程 (例如：汽车中的负载突降) 中限制和调节输出。另外，LTC4364 还包括一个定时的电流限制电路断路器。在故障情况下，一个可调故障定时器必须在传输器件关断之前结束。LTC4364-1 将锁断传输器件，而 LTC4364-2 则在一个延迟之后自动重新起动。LTC4364 可精确地监视输入电源的过压 (OV) 和欠压 (UV) 情况。外部 MOSFET 在欠压状况下保持关断，自动重试在过压状态下停用。
一个集成型理想二极管控制器负责驱动第二个 MOSFET，以替代一个用于实现反向输出保护和输出电压保持的肖特基二极管。LTC4364 可控制 MOSFET 两端的正向电压降，并最大限度地抑制电源故障、欠压或输入短路时的反向电流瞬变。
