20120253714 | BATTERY VOLTAGE MEASUREMENT - An apparatus is provided that includes a first circuit to determine when a battery current falls below a threshold, a second circuit to measure a battery voltage and current in response to the first circuit determining that the battery current falls below the threshold, and a third circuit to store the measured battery voltage and current. | 10-04-2012 |
20120254633 | POWER CONTROL MANAGER AND METHOD - A power control manager includes a processor to compute available power from a power source and a comparator to compare the available power to an amount of power to concurrently operate a plurality of sub-systems of an electronic device at full or a predetermined power. The processor generates one or more control signals in response to a decision signal output from the comparator. The control signals may indicate that a maximum power setting is to be set for a first sub-system and a reduced non-zero power setting is to be set for a second sub-system of the plurality of sub-systems. The sub-systems may be different sub-systems of a smartphone or another electronic device. | 10-04-2012 |
20130283083 | MAINTAINING OPERATIONAL STABILITY ON A SYSTEM ON A CHIP - Various embodiments are directed to maintaining operational stability for a system on a chip (SOC). A power management integrated circuit (PMIC) includes comparator circuits operative to monitor a current level on a power supply rail of the SOC. An interrupt management component may create an interrupt when the monitored current level crosses the threshold setting. The interrupt may indicate whether the current level has crossed the threshold setting into or out of excessive current levels. A microcontroller on the SOC coupled with the PMIC via a low latency interrupt channel over a communication interface may receive and interpret the interrupt. The microcontroller may be operative to change an operating point of one or more components on the SOC in response to the interrupt to alleviate an overcurrent situation. | 10-24-2013 |
20140189387 | STAGED POWER DISTRIBUTION CONTROL - Various embodiments are directed to restrictions in portable computing device electric power to accommodate reductions in the voltage level of a power source. An apparatus comprises a controller caused to receive configuration data from a main processor circuit specifying a voltage level threshold and selected action to take to reduce electric power to a first component in response to the voltage level falling below the first voltage level threshold, recurringly monitor the voltage level; based on the voltage level falling below the first voltage level threshold, take the first selected action and transmit a signal to the main processor circuit indicating that the voltage level has fallen below the first voltage level threshold and that the first selected action has been taken; transmit the voltage level to the main processor circuit; receive a signal from the main processor circuit to undo the first selected action; and so undo. | 07-03-2014 |
