G2012 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) G2012rz1u 2012 -20 c to +85 c tqfn3x3-20 note: rz: tqfn3x3-20 1: bonding code u: tape & reel pin configurations ch1~3 : cv/fs ch4 : cc/fs ch5 : cv/fs note: thermal pad must connect to ground. tqfn3x3-20 1 2 3 4 511 12 13 14 15 16 17 18 20 19 8 7 9 10 thermal pad 6 out2a out1b out2b vm out3a out3b out5a out4a out4b rnf4 pi1 in1 in2 in3 in4 vcc sdat sclk sld out1a 21 gnd note: thermal pad must connect to ground. tqfn3x3-20 1 2 3 4 511 12 13 14 15 16 17 18 20 19 8 7 9 10 thermal pad 6 out2a out1b out2b vm out3a out3b out5a out4a out4b rnf4 pi1 in1 in2 in3 in4 vcc sdat sclk sld out1a 21 gnd
