  • Publication number: 20170351322
    Abstract: An apparatus may include first circuitry coupled to one or more platform components, the first circuitry operative to receive an unfiltered input voltage signal, compare a first voltage level of the unfiltered input voltage signal to a first reference voltage level, and generate a control signal operative to lower operation power of one or more of the one or more platform components when the first voltage level is less than the first reference voltage level.

  • Patent number: 9345104
    Abstract: Systems and methods may provide for a power management apparatus including a first path to be coupled to an output of a narrow voltage direct current (NVDC) charger and an input of a backlight voltage regulator (VR). The apparatus may also include a second path to be coupled to an input of the NVDC charger and the input of the backlight voltage regulator, wherein the second path is to bypass current around the NVDC charger and to the input of the backlight VR if a voltage supplied by a first power source to the NVDC charger exceeds a voltage of a second power source coupled to the output of the NVDC. In one example, the first path includes a first diode and the second path includes a second diode, wherein the first and second diodes form an OR configuration for the apparatus between the first and second paths.

  • Publication number: 20140181546
    Abstract: An apparatus may comprise a platform power protection circuit to monitor an electric current over a platform input line, the electric current received on the platform input line from a current source, and output an alert signal from a comparator when current output is determined to exceed a current threshold. The apparatus may further include logic to assert a control signal to reduce power consumption in one or more platform components coupled to the platform input line when the alert signal is received. Other embodiments are disclosed and claimed.
