    Hi Red,

    Sorry for the confusion. The 7V rating is not for OUT pin. OUT pin should be the same as the VCC pin because VCC supplies the driver. The reason it is not shown in the table is because OUT pin is considered an output pin, and the customer is not supposed to supply a signal to an output pin. Ony the negative rating of the OUT pin is specified because it is externally forced on the pin.

    So, your OUT pin is safe for 7.2V.

    Thanks,
    Youhao
