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. ordering information order number marking temp. range package (green) G2009rz1u 2009 -20 c to +85 c tqfn3x3-20 note: rz: tqfn3x3-20 1: bonding code u: tape & reel pin configurations ch1~3 ? cv/fs ch4 ? 4a:cc/cv/fs 4b:cc/fs note: recommend connecting the thermal pad to the ground for excellent power dissipation.
