Applications

„ Stepping motor driver/ DC motor driver motor driver for DSC General Description G2022 is a 8i+1-channel H-Bridge motor drivers IC for the digital camera and so on. It has eight full-swing/constant voltage drivers and one full- swing/constant current/constant voltage drivers. G2022 can be operated in serial control mode or partial exterior control mode. When operating in partial exterior control mode, the mode of each CH is fixed by initial serial control setting. When operating in serial control mode, the mode of each driver can be setting by serial control. The serial interface ( I2C) that operates at clock rates up to 400 KHz.
