Camera module driving apparatus and device including camera module

Abstract

A camera module driving apparatus includes: a camera module driving IC including a communication port and a driving port; an interface to receive a communication signal through the communication port; and a driver to output a driving current through the driving port and including driving semiconductor circuit elements coupled in a bridge structure. The interface includes an inverter including a high-voltage terminal, a low-voltage terminal, and an input terminal and operating based on a voltage difference between the high-voltage terminal and the low-voltage terminal, and inverting at least a portion of the communication signal; and an input semiconductor circuit element passing current from the input terminal to the high-voltage terminal and cutting-off the current from the high-voltage terminal to the input terminal. The high-voltage terminal and the low-voltage terminal of the inverter are electrically connected to both ends of a capacitor, respectively.
