Applications
Stepping motor driver/ DC motor driver motor d r i v e r f o r D S C General Description G2012 is a 4+2-channel H-Bridge motor drivers IC for the digital camera and so on. It has four full-swing/constant voltage drivers and one full-swing/constant current drivers. G2012 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.
