    Hi everybody,

    I am trying to drive an electrovalve which is open when it is supplied with +12V and closed with -12V. The open signal has to be controlled by a MSP430 which is supplied to 3V. I have in the board a 12V Dc/Dc to supply the electrovalve but cannot add more Dc/Dc converters.

    The H bridge L293D would be perfect, but it need 5V.
    I would like the same features of the L293D but supplying the IC at 3V.

    Do you know any chip is doing the work of L293D with 3V?

    Thank you very much

    Michele
