  "textContent": "A charge and power supply circuit includes: a first switch coupled between a first node and a positive terminal of a battery; a second switch coupled between a USB connector and one of the first node and a second node; a third switch coupled to a load in series between the first and second nodes; and a control unit controlling the switches. In a USB charge mode, an input voltage from the USB connector is permitted to charge the battery via the conducting first and second switches. In a battery supply mode, the battery is permitted to supply a battery voltage to the load via the conducting first and third switches. In a USB supply mode, the input voltage is permitted to be supplied to the load via the conducting second and third switches.",
