    • Systems and methods for reducing problems and disadvantages associated with traditional approaches to masking false faults generated by voltage regulators are provided. A method may include receiving, at a voltage regulator configured to be enabled by a power controller communicatively coupled to the voltage regulator via an enable line, a first indication from a device other than the power controller indicating that the voltage regulator is to be disabled, wherein the enable line is configured to communicate a second indication from the power controller to the voltage regulator indicating whether the voltage regulator is to be enabled. In response to receipt of the first signal, the voltage regulator may communicate to the power controller via the enable line, a third indication indicating that the voltage regulator has been disabled by a device other than the power controller.
    • 提供了用于减少与由电压调节器产生的伪故障的传统方法相关联的问题和缺点的系统和方法。 一种方法可包括在电压调节器处经由经由使能线通信地耦合到电压调节器的功率控制器被配置为使得能够从功率控制器之外的设备指示电压调节器被禁用的第一指示, 其中所述使能线被配置为将来自所述功率控制器的第二指示传送到所述电压调节器,以指示是否启用所述电压调节器。 响应于接收到第一信号,电压调节器可以经由使能线路与功率控制器通信,指示电压调节器已被功率控制器以外的设备禁用的第三指示。
