概览

TPS2398 和 TPS2399 集成电路是热插拔电源管理器，适用于标称 −48 V 系统。它们的断路器响应有所改进，可快速提供针对短路的保护，同时插件还能够承受突然切换到更高电压电源时可能产生的大瞬变。它们的设计电源电压范围可达 −80 V，额定承受峰值达 - 100v。它们与外部 N 沟道 FET 和感应电阻相结合，可以用于实现在加电系统中实时插入插卡和模块。这两种器件都提供负载电流摆率和峰值幅度限制，易于通过感应电阻器值和单个外部电容器进行编程。 它们还提供单线故障报告、故障卡电气隔离和防止滋扰过电流跳闸。TPS2398 会响应电流故障关断锁存，而 TPS2399 会在发生故障时周期性地重试负载。
