TAS5630B damaged in PP, total 100 PCS of 200, fail ratio is 50%. I found abnormal waveform on RESET PIN when switch Signal source , the voltage on RESET pin usually is 3.3V, but when did fast switch signal source ,the voltage will drop to 1V or 2V, attachment is the sketch for your REF. Could you please help check if this operation can cause TAS5630B damaged ? Thanks .

Hi Haiwen,

Have you checked the FAULT pin? Did the FAULI happen?

What about the inductor spec of the output?

Can you share the schematic to us?

Derek,

Yanming:

fault pin is floating , attachments are the schematic and indicator spec for your reference . PBTL mode is much easy burning , BTL mode is less burning . Could you please help check the root cause ?Thanks .
