    I'm working on a project that will use the L293d motor driver (maybe)
    to control an electromagnetic output device drawing approximately
    300ma at 24v ie about 7.2 W Datasheet says that the L293d has a total
    power dissipation of 4w. In effect, does that mean that the power
    dissipation of my outpu device will also be limited to 4w, or does it
    mean that the driver's components can dissipate 4w through itself, but
    this is separate from the power used by output device. eg the driver
    might be using, say, 2w of power for its components to operate my
    output device, which itself is using approximately 7w power

    If so, how can I work out approximately how much power the driver
    might use to operate an output device mentioned? Thanks in advance,
    Peter
