Abstract: An electronic device may include a battery charger and a controller. The battery charger may receive a voltage from an energy source, and may provide an output power. The controller may receive a voltage value of the energy source, may receive a current value from the battery charger or the energy source, may determine a power value based on the received voltage value and the received current value, and may provide at least one control signal to the battery charger to change the output power of the charger.

Abstract: A system for increasing the life of a battery cell by limiting the charging of the battery to less than full charge in response to a predicted electricity draw of a connected device being less than the full capacity of the battery before a predicted recharge will occur. The current draw of the connected device may be affected by the amount of time before a next recharge and environmental factors. The system may further comprise one or more sensors to gather data pertaining to environmental conditions that may be used in the calculation of a charge termination value. The charge termination value is an amount of charge to power the device for a duration of time at least until a predicted recharge begins.

Abstract: Methods and apparatus relating to controlling the supply of power to computing devices with dynamically variable energy capacity are described. In one embodiment, logic causes modification to supply of power from a power source to one or more loads in response to a comparison of an output of the power source and a threshold value. The output of the power source may vary over a time period (e.g., oscillating) that causes the one or more loads to become inoperational. Other embodiments are also disclosed and claimed.

Abstract: Methods and apparatus relating to low cost and/or low overhead serial interface for power management and other IC (Integrated Circuit) devices are described. In an embodiment, a unique address is assigned to each of a plurality of slave devices. The plurality of slave devices are coupled in a daisy chain configuration. And, any access directed at a first slave device from the plurality of slave devices is allowed based at least in part on comparison of an address of the first slave device and an address associated with the access. Other embodiments are also disclosed and claimed.

Abstract: Generally, this disclosure describes an apparatus. The apparatus includes switch controller circuitry and zero crossing logic circuitry. The switch controller circuitry is to control a conduction state of a high side switch and a low side switch in a DC to DC converter. The zero crossing logic circuitry includes phase comparator circuitry, a first clocking circuitry and a second clocking circuitry. Each clocking circuitry includes one or more delay elements. The zero crossing logic circuitry is to monitor a switch node voltage, Vsw, and to determine whether Vsw is greater than a reference, Vref. The switch controller circuitry is to turn off a low side switch if Vsw is greater than Vref while the low side switch is turned on, Vsw greater than Vref corresponding to a negative inductor current.
