Camera module driving apparatus and device including camera module

A camera module driving apparatus, comprising:

• a camera module driving integrated circuit (IC) including a communication port and a driving port, wherein the camera module driving IC comprises a power port configured to receive IC power;
• an interface configured to receive a communication signal through the communication port in the camera module driving IC;
• and
• a driver configured to output a driving current through the driving port in the camera module driving IC and including driving semiconductor circuit elements coupled in a bridge structure,
• wherein the interface comprises:
• an inverter including a high-voltage terminal, a low-voltage terminal, and an input terminal and configured to operate based on a voltage difference between the high-voltage terminal and the low-voltage terminal, and to invert at least a portion of the communication signal input from the input terminal, wherein the voltage difference between the high-voltage terminal and the low-voltage terminal is lower than a voltage difference between a voltage of the IC power of the power port and a ground;
• and
• an input semiconductor circuit element configured to pass current from the input terminal of the inverter to the high-voltage terminal and to cut off the current from the high-voltage terminal to the input terminal,
• wherein the high-voltage terminal and the low-voltage terminal of the inverter are electrically connected to both ends of a capacitor, respectively.
