Abstract: Faster charging of a battery, including: opening a first switch disposed between an input node of the battery and an input node of a load to decouple the input node of the battery from the input node of the load; and charging the battery using a first charging source coupled to the input node of the battery while the load is being powered through the input node of the load via a second charging source having a charge rate slower than the first charging source.

Abstract: Systems and methods for reuse of battery pack-side current and voltage sensing are disclosed. By reusing elements within a battery pack, a battery field effect transistor (FET) within a power management integrated circuit (PMIC) may be eliminated or at least bypassed. In a first aspect, a current mirror is coupled to a charge protection circuit in the battery pack to capture a sensed current. Likewise, a voltage sensor captures a voltage level for a charging path. Current and voltage are output to the PMIC for use in regulating a buck charger. In a second aspect, current data and voltage data are collected and digitized before being sent to the PMIC for use in regulating the buck charger.

Abstract: Particular embodiments include logic that can reduce an voltage output of a regulator to multiple subsystems in response to detecting high power conditions in an electronic device. When the power being monitored goes up, the logic detects the increase in power. Then, the logic can compare the power to a plurality of thresholds. The plurality of thresholds may be set below an absolute limit threshold in which the electronic device may not operate properly if the absolute limit is met. When a first threshold is met, the output voltage of the regulator may be decreased until a minimum voltage level is reached. When a second threshold is met, the output voltage may be increased until a maximum voltage level is reached. The minimum and maximum voltage levels may be based on voltage levels requested from a set of subsystems and also priority levels associated with those subsystems.

Abstract: An apparatus and method for to incrementally reduce (e.g., de-rate) a power supply voltage output (VOUT) of a regulator to multiple subsystems in response to detecting high power conditions in a client device is described. In one instance, multiple low power client devices and a high power consumption client device are coupled to a power grid of the power management system with a power management integrated circuit (PMIC) supplying power to the power grid. The PMIC includes a buck-or-boost switching regulator including a load current adjustment device to de-rate the high power consumption device when a sum of the current consumed by the high power consumption device and the low power client devices is above a predetermined threshold.
