Charger system with dual-level current regulation and dual-level thermal regulation |
摘要 |
A charging system that concurrently charges a main system and a battery for powering the main system when the charging system is connected to an adapter. The charging system includes a current sensing resistor, a first current control circuit for regulating the current in a linear battery charger and a second current control circuit for controlling the maximum adapter current. The charging system further includes a first temperature control circuit for regulating the current in the battery charger and a second temperature control circuit for controlling the maximum power dissipation of the charging system. The charging system further includes a linear regulator for providing power to the main system from the adapter and a main system voltage control circuit and a battery voltage control circuit. The charging system apportions the adapter current between the main system and the battery charger giving priority to the main system.
