TAS6424E-Q1: The difference between fault pin and warn pin?

Tool/software:

Hello Team,

If the SOC dosen't  have PWM pins, which means we can't use TAS6424E warning function?

What's the difference between warn pin and fault pin?

    Ailing,

    The basic difference is that a Fault will place a channel or all channels in Hi-Z mode to protect the device from a fault.  A Warn or warning will not place a channel or all channels in Hi-Z mode but provide a warning that a fault may be imminent, and one should take action.  The only warning that is different is a POR.    See table 9-5 in the datasheet.
