Abstract: A method for detecting removal of a battery from a battery charger includes 1) incrementing an event counter and resetting an interval counter each time the voltage present at the output node exceeds a predetermined voltage; 2) resetting the event counter each time the interval counter exceeds a predetermined maximum time between events; and 3) asserting a signal indicating the absence of a battery connected between the positive and negative output nodes each time event counter exceeds a predetermined number of events.

Abstract: Charge storage devices (e.g., batteries or supercapacitors) need to be charged from time to time. In an apparatus, to protect a charge storage device as well as the supply used to charge it, the apparatus typically includes power loop control circuitry. One approach to implementing the power loop control employs a temperature sensor in combination with soft start circuitry in order to protect the circuitry from a rapidly increasing temperature when charge current increases. The soft start circuitry allows for controlled step-wise increase and regulation of the current. The approach preferably allows for selecting the number and resolution of such incremental steps. Various embodiments of the invention include devices and methods for controlling power and may take into account temperature in step-wise regulation of the charge current.

Abstract: A battery charger for a portable electronic device includes a linear charger to generate a substantially constant current for charging the battery and a switching voltage regulator to convert power supplied by an external adapter to a supply voltage for the linear charger. A feedback circuit controls operation of the switching voltage regulator so that the voltage supplied to the linear charger is substantially equal to the combination of the battery voltage and the drain-to-source voltage of the linear charger. In this way, power dissipation by the linear charger is minimized without requiring the use of a high accuracy current limited adapter.
