NotesThe polarity signs shown in the output terminal names indicate the polarities when corresponding

input pins are set to (+).

On the power supply terminals of the output H bridge, PVcc2 is set for the focus and tracking

drivers, PVcc1ｋ for loading, and Vcc for feed motor.

The power supply systems of the pre part are all set to Vcc.

Make sure that this device must be used under the following condition: VCC

≥ PVcc.
