System, method and semiconductor device for charging a secondary battery

摘要

A system comprises a rechargeable battery 214 that is coupled to a semiconductor device 200. The rechargeable battery receives a charging current during a charging cycle. The charging cycle also includes a plurality of intermittent no-charge time intervals where the battery receives a significantly reduced charging current from the semiconductor device. The system may also comprise a housing for the rechargeable battery and semiconductor device, an adjustable current source 204 and a feedback control module 212.
