    I need a high side current limited switch for about 6A. I need it to work from 5 (or 4.5) volts to 9v or so. I need this for a 6 volt version of an existing 12 volt controller. I now use the IR331* drivers but they don't work below 7 v. I found a few devices, but they're way proud of them. I'm not sure the project can support an extra twenty + dollars for a 6v version. Since I can't find any high side drivers, is there a power supply IC with a built in mosfet that would work, or some power supply switch or sequencer you think would work? Space is a premium. I don't have much more room than the IR331* use so I'm looking for an integrated solution.

    Thanks
