Battery charging system with trickle charging/discharging control
A circuit for charging and/or discharging a battery includes a switch coupled to a battery in series, and a driving transistor coupled to the switch and operable for sensing a voltage of the battery. The driving transistor is turned on if the voltage of the battery is less than a predetermined threshold. A driving current flowing through the driving transistor determines an on-resistance of the switch.
