G2001 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) G2001rg1u 2001 -20c to +85c tqfn5x5-40 note: rg: tqfn5x5-40 1: bonding code u: tape & reel pin configurations ch12:micro_stepping ch34:micro_stepping ch5: cc/cv/fs ch6: cc/cv/fs rnf6 pi1 vcc reset out6b out6a vm6 in6 in5 oscin pi3 mob2 ext1 / st1 out2b out2a vm12 out1b pgnd12 out1a gnd ext2 / st2 out3a pgnd34 out3b vm34 out4a pgnd34 1 2 3 4 5 6 7 8 9 10 in4 sld sclk sdat vm5 out5a rnf5 out5b 11 12 13 14 15 16 17 18 19 20 G2001 tqfn5x5-40 thermal pad 30 29 28 27 26 25 24 23 22 21 40 39 38 37 36 35 34 33 32 31 pi2 out4b pgnd12 in3 note: thermal pad must connect to the ground for excellent power dissipation. mob1 / sdo rnf6 pi1 vcc reset out6b out6a vm6 in6 in5 oscin pi3 mob2 ext1 / st1 out2b out2a vm12 out1b pgnd12 out1a gnd ext2 / st2 out3a pgnd34 out3b vm34 out4a pgnd34 1 2 3 4 5 6 7 8 9 10 in4 sld sclk sdat vm5 out5a rnf5 out5b 11 12 13 14 15 16 17 18 19 20 G2001 tqfn5x5-40 thermal pad 30 29 28 27 26 25 24 23 22 21 40 39 38 37 36 35 34 33 32 31 pi2 out4b pgnd12 in3 note: thermal pad must connect to the ground for excellent power dissipation. mob1 / sdo
