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.
