BA6849 is a intergrated circuit diven by the BA6849 three-phase spindle motor, which can translate the defult control signal of the spindle into three-phase drive voltage and therefore drives the three-phase spindle motor. This circuit is used in the cores of DVD players. As shown in figure 1 is the internal circuit of BA6849 chips, it is pinned in flat type 28 with cooling ribs, the pin functions and data are listed in figure 1 in which the pinnings ①、③、⑤、⑥、(16)、(19) are listed at the foot of the page.
