G2005 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. ordering information order number marking temp. range package (green) G2005k11u 2005 -20 c to +85 c tqfn4x4-32 note: k1: tqfn4x4-32 1: bonding code u: tape & reel pin configurations ch1~3: cv/fs ch4 :cc/cv/fs ch5 :cc/fs out1a in1a in1b in2b note: recommend connecting the thermal pad to the ground for excellent power dissipation.
