Abstract

A low voltage charging control and protection circuit for an electronic cigarette is provided. The circuit includes an extended charging circuit configured to charge a battery of the electronic cigarette at a first voltage. The circuit also includes a charging integrated circuit configured to charge the battery of the electronic cigarette at a second voltage. The first voltage is lower than the second voltage. The circuit further includes a microcontroller configured to control the extended charging circuit and the charging integrated circuit to alternately charge the battery of the electronic cigarette based on a high or low level of a voltage of the battery.
