TAS6424E-Q1: audio not working after load dump (40V / 300ms)

Part Number: TAS6424E-Q1

Tool/software:

Hello TI Team,

During KL30 battery load dump (40V / 300ms) customer in their automotive head unit application lost audio signal.

After battery voltage return to to 16V audio still did not work.

 

Will TAS6424E-Q1 auto recovers after overvoltage conditions automatically?

Inside datasheet I have not found any "latch" function that would put device into any safe-mode... please help to understand this scenario.
