Hi Team，
The PVDD is 24V and the GVDD is 12V in my application, the attachment is my schematic.
one heat sink is attached on the TPA3255.
When the reset signal is low and the actually voltage of the 24V power rail is about 12V(the input power supply of my application is from a 12V battery package, the 24V PVDD souced from a boost power module of the battery packege, and the 12V GVDD is from a buck power supply of PVDD), the heat sink is hot. I`d like to know what the TPA3255`s status is when the RESET is low, and what is the reason of this hot phenomenon？Because the total power supply of my application is from a 12V battery package, so I`d like to avoid all of the unused power consumption, please give me some hints for the hot phenomenon. Look forward to your reply!
Br,
Shawn
