G2007 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) G2007rg1u 2007 -20 c to +85 c tqfn5x5-40 note: rg: tqfn5x5-40 1: bonding code u: tape & reel pin configurations ch1~4: cv/fs ch5 : cc/cv/fs ch6 : cc/fs in2a sld reset in1a in1b in2b vcc in3a in3b pi3 pi2 out1a vm12 out2a out5a rnf5 out5b vm5 sdat sclk in5a in5b gnd in6a in6b in4a in4b 1 2 3 4 5 6 7 8 9 10 vm34 out4a out4b out6a rnf6 out6b vm6 pi1 11 12 13 14 15 16 17 18 19 20 G2007 tqfn5x5-40 thermal pad (ep) 30 29 28 27 26 25 24 23 22 21 40 39 38 37 36 35 34 33 32 31 out3a nc out2b out3b note: thermal pad must connect to the ground for excellent power dissipation. out1b top view in2a sld reset in1a in1b in2b vcc in3a in3b pi3 pi2 out1a vm12 out2a out5a rnf5 out5b vm5 sdat sclk in5a in5b gnd in6a in6b in4a in4b 1 2 3 4 5 6 7 8 9 10 vm34 out4a out4b out6a rnf6 out6b vm6 pi1 11 12 13 14 15 16 17 18 19 20 G2007 tqfn5x5-40 thermal pad (ep) 30 29 28 27 26 25 24 23 22 21 40 39 38 37 36 35 34 33 32 31 out3a nc out2b out3b note: thermal pad must connect to the ground for excellent power dissipation. out1b top view
