Hello ,
I have a big problem. Just for seeing signals and pin conditions , i did not connect resistor loads to tas5630 board and start looking with scope. I saw triangle signal on osc pins ,and also saw square signal on BST pins , sd otw ready pins conditions are same as in pdf normal operation chart , everythings are right as i expect , but just 30 or 40 seconds later chip is dead , i did not explain this and i changed the tas5630 and looked same pins again ,and all pins signals are same as before ,but after 30 or 40 seconds later tas5630 was also dead , SD pin is low and i reset chip or power off the board wait 3-5 minutes but no signal from chip. All clock, bst signals are off. I dont use heatsink , because i need to see pins on scope screen , because of this i dont connect loads. I only change the value of ınductors in my design ,others are same in application. In Texas application inductor value is 7uH , i change it to 10uH. What will be the problem? I use TAS5630BPHDR .
