G2002 /G2002b 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) G2002rv1u 2002 -20 c to +85 c tqfn4x4-28 G2002brv1u 2002b -20 c to +85 c tqfn4x4-28 note: rv: tqfn4x4-28 1: bonding code u: tape & reel pin configurations ch12:micro_stepping ch3 :cv/fs ch4 :cv/fs ch5 :cc only G2002/G2002b tqfn4x4-28 rnf5 out5b vm45 out4a p13 out4b out1a out1b vm12 out2a out2b out3a 1 2 3 4 5 6 16 17 18 19 20 21 in5 oscin in4 gnd ext out5a 27 22 23 24 26 25 sld vm3 vcc 8 9 10 11 12 sclk sdat thermal pad (pgnd12,pgnd3) 7 pi2 13 14 mob/sdo p11 15 in3 28 out3b note: recommend connecting the thermal pad to the ground for excellent power dissipation.
