description

LT^®4250L / LT4250H 是 8 引脚、负 48V 热插拔 (Hot Swap™) 控制器，允许电路板在带电的背板上安全地插入和拔出。通过控制一个外部 N 沟道通路晶体管的门极电压，浪涌电流可被限制在一个可设置的数值上。如果输入电压小于可设置的欠压门限或大于过压门限，则该通路晶体管会被关断。可设置的电流限值保护系统不受短路的破坏。在一个 500us 的限时之后，电流限值启动电子电路断路器。PWRGD(LT4250L) 或 PWRGD (LT4250H) 信号可被用于直接使能一个电源模块。LT4250L 专为具有低使能输入的模块而设计，LT4250H 则专为高使能输入的模块而设计。

LT4250L / LT4250H 采用了 8 引脚 PDIP 和 SO 封装。
