ADM1070集成电路（IC）的热插拔控制器规格书PDF中文资料

ADM1070属于集成电路（IC）的热插拔控制器。由亚德诺半导体技术有限公司制造生产的ADM1070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。

GENERAL DESCRIPTION

The ADM1070 is a negative voltage hot swap controller that allows a board to be safely inserted and removed from a live –48 V backplane. The part achieves this by providing robust current limiting, protection against transient and nontransient short circuits and overvoltage and undervoltage conditions. The ADM1070 typically operates from a negative voltage of up to –80 V and can tolerate transient voltages of up to –200 V.
