0.5V 以上的电源电压监控器可在纤巧型封装内集成多达 6 个电源监视器。许多器件具有一种用户可选门限功能。
按钮控制器:按钮控制器提供了用于 DC/DC 转换器、处理器中断逻辑电路和可调接通/关断定时器的启用控制。这种器件轻松地解决了所有机械触点固有的反跳问题,同时还可在电源完全上电的情况下启用电源转换器并释放一个处理器。与分立型解决方案相比,这些器件提供了宽电源电压范围、小外形尺寸、低静态电流和设计的简易性。(5)型号 | Supply Voltage Range | Features | Isupply | Comments | Extended Temp | Packages | 数据手册DataSheet下载 |
