G2030 can be opera ted in serial control mode or partial exterior control mode. when operating in partial ex terior control mode, the mode of each ch is fixed by initial serial control setting. when operating in serial co ntrol mode, the mode of each driver can be setting by s erial control. ordering information order number marking temp. range package (green) G2030k11u 2030 -20 c to +85 c tqfn4x4-32 note: k1: tqfn4x4-32 1: bonding code u: tape & reel pin configurations out1a in1 in2 in4 note: recommend connecting the thermal pad to the ground for excellent power dissipation.
