General Description
G2018 is a 5+1-channel H-Bridge motor drivers IC for
the digital camera and so on. It has one micro-stepping
driver, two full-swing/constant voltage drivers and one
full-swing/constant current drivers. G2018 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.
