TAS6584-Q1: Output short to battery, VBAT and PVDD are risen until the TAS6584 does not work.

Part Number: TAS6584-Q1

VBAT=12V

PVDD=35V(DCDC boost)

output:1kHz/0.1W/4ohm

When speaker shorts to 12V, VBAT begins to rise, once it reaches 35V, the voltage of VBAT and PVDD will be raised together. After 165ms, the OUT_xP no outputs and the VBAT and PVDD voltages drop.

How to get the VBAT and PVDD to boost?
