SC4250数据手册集成电路（IC）的热插拔控制器规格书PDF

特性 Features

·Allows insertion of line cards into a live backplane
·Programmable slew of the inrush current when used for hot insertion in the negative 24 V and 48 V backplane
·Closed-loop operation limits the maximum current even in short-circuit condition
·Built-in timer prevents false shutdown when the closed-loop operation limits the current
·Sensing the drain voltage allows for immediate shutdown in short-circuit conditions where current spikes and noise are ignored
·Power-good signal
·Input UVLO and OVLO sensing
·Circuit breaker and retry
·SO-8 package

应用 Application

·Central office switching
·Negative 48 V distributed power systems
·Power supply hot-swap & inrush control

简介

SC4250属于集成电路（IC）的热插拔控制器。由制造生产的SC4250热插拔控制器PMIC - 热插拔控制器是能提供电路内保护和控制功能的半导体，可允许带电情况下在电路中插入或拔除其他组件。热插拔控制器可用于计算机网络和通用电源系统，主要根据输出电流、受控通道数量等特性，以及自动重试、故障超时和保护等特殊功能进行区分。
