POWER MANAGEMENT CIRCUIT TO MANAGE DISTRIBUTION OF RECEIVED POWER AND A PORTABLE APPARATUS HAVING THE SAME
摘要：
A portable apparatus includes a system configured to receive a system current and perform a function, a charging battery configured to be charged with a charging battery current and supply power to the system, and a power management circuit configured to receive an externally supplied power, supply the system current to the system, and supply the charging battery current to the charging battery based on a sensed level of the system current, wherein the charging battery current decreases in proportion to the system current.
摘要（中）：

一种便携式设备包括：被配置为接收系统电流并执行功能的系统;配置为对所述系统充电电池电流并向其供电的充电电池;以及电源管理电路，其被配置为接收外部供应的电力， 系统电流到系统，并且基于感测到的系统电流电平将充电电池电流提供给充电电池，其中充电电池电流与系统电流成比例地减小。
