TPS65023: Low_Bat Comparator freely usable?

Hi there,

 

am I reading the '65023 datasheet right that the LOW_BAT comparator is quasi a stand alone device, powered by  the Vmax switch and simply comparing the LOWBAT_SNS pin to an internal 1V reference (powered by what?), resulting in the LOWBATn signal.

IOW: am I free to use this comparator to survey what ever (switcher-)output voltage of the chip?
Or is there some connection to the control logic in the '65023  that could provoke unplanned side effects when the comparator triggers?

    Hi Stefan,

    You posted the question on the wrong forum. I guess you need to post this on - http://e2e.ti.com/forums/100.aspx

    This forum is specific to TPS659xx devices (companions to OMAP2/3).

     

    Regards,

    Gandhar.

    Oops - seems I read "Technical discussion about power analog companion devices for the OMAP™ Applications Processor & TPS659xx family ICs" the wrong way. [:|]
    Maybe you should delete the "and" and emphasize the 659xx a little more. [;)] 

    Thanks for the hint. Let's see if I get annother 'slap' for posting about an IC with switchers in a linear regulator forum... [:D]

    Edit / Update:
    LOL! My question has been moved from the "linear regulators" to the "isolated controllers" forum. I didn't know that the TPS65032 houses such one!

    Am I the first one to use this chip?? Any alternatives?
