Part Number: TPA3138D2

Hi,

I want to use TPA3138,

I find in datasheet,

Why in BD mode, UV is 7.5V?

While in 1SPW mode , UV is 3.5V?

Is there any bug in BD mode when PVCC is low?

Thanks!

Hi Jiciwi,

1SPW is designed for low-power consumption application, which ask it to support lower PVDD voltage. Hence we design UV to be 3.5V. While BD mode, it is commomly designed as 7.5V UV. There is no bug for this feature.

If you have any concerns about this feature, please clarify with more details based on your application. We will support to explain more.

Regards,
Alix Wan.

I think in BD mode, it also can work in low PVCC. I just want to know Why design this? For example, TPA3118, it support two mode in low PVCC.
