ABB of AM5728

Other Parts Discussed in Thread: AM5728, TPS659037

Hi,

I have one question regarding ABB (Adaptive Body Biasing) of AM5728.

Now my customer uses TPS659037 as a PMIC with AM5728.

And VDD_DSPEVE, VDD_GPU and VDD_IVAHD are connected to same SMPS output(SMPS45).

For AVS, customer uses the same setting for three VDD(DSPEVE, GPU, IVAHD). It is for VDD_GPU.

Customer does not use DSP and IVAHD.

And then, now customer does not set ABB for these three vdd. Now only VDD_MPU is set for ABB.

However, according to the data manual of AM572x,  AVS and ABB are required.

How should customer set the ABB for VDD_DSPEVE, VDD_GPU and VDD_IVAHD?

Please advise me .

I appreciate your quick reply.

Best regards,

Michi
