Battery switch driving circuit

A battery switch driving circuit comprising:

• a first battery input terminal and a second battery input terminal;
• a converter positioned between the first battery input terminal and the second battery input terminal;
• a fourth switch and a fifth switch positioned between the second battery input terminal and the converter, and configured to block power input in opposite directions when turned off;
• and
• a switch driving unit configured to turn on the fourth switch and the fifth switch,
• wherein the switch driving unit comprises:
• a first capacitor charged and discharged according to on/off of a second switch operated by a PWM signal;
• and
• a second capacitor charged according to on/off of the second switch by voltage charged in the first capacitor, and configured to turn on the fourth switch or the fifth switch, and
• wherein one end of the first capacitor is connected to one end of the second capacitor and an other end of the first capacitor is connected to an other end of the second capacitor.
