G2008 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. applications stepping motor driver/ dc motor driver motor driver for dsc ordering information order number marking temp. range package (green) G2008rv1u 2008 -20 c to +85 c tqfn4x4-28 note: rv: tqfn4x4-28 1: bonding code u: tape & reel pin configurations ch1~3:cv//fs ch4 :cc//fs ch5 :cv//fs G2008 tqfn4x4-28 in4 in3 in2 in1 sld sclk out1b out2a out2b out3a out3b out5a 1 2 3 4 5 6 16 17 18 19 20 21 vcc p13 vm12 gnd p12 p11 27 22 23 24 26 25 sin1 rnf4 sin2 8 9 10 11 12 vm345 out4b thermal pad 7 sout2 13 14 sout1 sdat 15 out1a 28 out4a note: recommend connecting the thermal pad to the ground for excellent power dissipation.
