1.function featuresAN8481SQ is supposed to convert the spindle servo error control signals into 3-phase drive voltages to drive the motor, whose internal circuit is shown is Figure 1. 2.pin functions and dataAN8481SQ has a function of overheat protection, which is in flat 28-lead package with cooling fins. It is used in GD2O0l DVD player of Hitachi, whose pin functions and data are listed in Table 1. In the table, the pins of (21), (23) and (24) are empty, (14) and (16) are earth terminals, (28) is the earth terminal of the drive circuit.
