TPA3116D2-Q1: TPA3116D2-Q1 design issue

Part Number: TPA3116D2-Q1


Dear TI,

I use powerIC to design the circuit,there is one issue need your support.

due to the powerIC fully controlled by hardware, there is a big pop(about 500uV) happen when the power supply is directly powered down.

I pull up mute pin(mute powerIC) when power supply down to 8V to avoid the pop happen, yet it doesn't work.

could you tell me how to reduce the pop(or the sequence how to avoid the pop) when the power supply is directly powered down?


Best Regards
