具有限流指示功能的双通道电源开关

EUP3546是一种双通道的电源开关芯片，内部集成了两个95mΩ 的P型MOSFET功率管，每个通道各有一个逻辑使能控制信号。\n当负载超出限制范围或者有短路情况发生的时候，芯片会进入限流模式，把负载电流控制在安全区域内，同时拉低限流指示信号OCB(s)，EUP3546的每个通道的限流电流设置典型值均在1A，并且具有fold back功能；如果持续存在超重负载或者短路情况，芯片内部温度和功耗将迅速上升，芯片将检测到过温状况，并自动进入保护状态，切断功率通道以防止芯片损毁；另外，EUP3546还具有检测输入电源的功能，功率管会维持关断直到电源电压超过欠压阈值范围。\nOCB(s)是具有开漏输出的 •双通道95 mΩ High-Side MOSFET\n•1A限流电流，且具有fold-back功能\n•工作电压范围:2.7V to 5.5V\n•300µs 输出电压上升时间\n•欠压保护功能\n•15µA 静态电流\n•1µA 关断电流\n•低电平逻辑使能控制\n•芯片关断后没有反向电流\n•具有延时功能的开漏输出限流指示信号\n•SOP-8,SOP-8(EP)封装\n•符合RoHS规范及Pb-Free;
