5+1CH serial input motor driverIC for DSC

General Description
G2028 is a 5+1-channel H-Bridge motor drivers IC for the digital  camera  and  so  on.  It  has  four  full-swing/constant  voltage  drivers  and  two  full-swing/constant  current  drivers.  G2028  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.

Features „
Built-in 4 full-swing/constant voltage drivers switched by serial control with brake function „   
Built-in  2  constant  current  drivers  for  shutter  or  IRIS „  
Low  on-resistance  (1.2Ω,  sum  of  on-resistance  of  up side and bottom side) „  
Output  current：IOUT<=0.8A(max.) for each channel„  Built-in thermal shutdown (TSD, 150°C) „  
Built-in CC mode weak excitation „  CH1/2 corresponds to STM control of 2-2 phase or 1-2 phase „  
Built-in exclusive control mode: CH13/23 Æ the combination control mode of 6CH is set „  
All  power  supply  systems  (VCC,  VM12,  VM3,VM45)  can  be  set  up  with  an  independent  power  supply „  
Power save mode corresponds by serial control setup „  PI (photo interrupter drive) 3 channel built-in.   „  
Small 32TQFN (4×4mm) is adopted

Applications   
Stepping motor driver/ DC motor driver for DSC
