Title
(ZH) 一种隔离电路系统及其进行信号隔离的方法
Abstract
(ZH)
本发明公开了一种隔离电路系统及其进行信号隔离的方法,该电路系统包括:电源管理器,用于监测到第一电路区域掉电时输出第一信号到数字逻辑电路,未监测到第一电路区域出现掉电时输出第二信号到数字逻辑电路;数字逻辑电路,用于将从电源管理器接收的第一信号经逻辑处理后输出隔离信号到隔离电路,将从电源管理器接收的第二信号经逻辑处理后输出连通信号到隔离电路;隔离电路,用于将所述交互信号进行阻断,或者,将所述交互信号经稳压处理后输出到第二电路区域。本发明有效地解决了在低功耗技术领域中,现有的隔离电路在突发掉电时,不能及时将输入到常开电压域的信号维持在固定的状态的问题,提升了隔离电路系统的稳定性。
