Abstract
Official abstract text for this publication.
Disclosed herein are some embodiments for safely charging a mobile system battery pack, even when the power source (e.g., adapter) voltage is at a relatively high level that would otherwise result in excessive charge current.
First claim
Opening claim text (preview).
What is claimed is: 1. An apparatus, comprising circuitry to: couple a power source to a battery of a system to pulse charge the battery; monitor the power source to decrease charge current to the battery if an input current is exceeded; and variably control a pulse duty cycle to charge the battery based on a level of the output voltage of the power source and information received from the battery, wherein the pulse duty cycle dynamically adjusts the average charge current to…
