1-2 phase.
„ Built in exclusive control mode: CH13/23 Æ the
combination control mode of 5CH is set.
„ Built in exclusive control mode: CH3/4(for DCM)
Æ the combination control mode of 6CH is set.
„ Power save mode corresponds by serial control
setup.
„ PI (photo interrupter drive) 3 channel built-in.
„ Small 20TQFN (3×3mm) is adopted.
Applications
„ Stepping motor driver/ DC motor driver for DSC
General Description
G2009 is a 4+2-channel H-Bridge motor drivers IC for the
digital camera and so on. It has three full-swing/constant
voltage drivers and one full-swing/constant current drivers.
G2009 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.
