Power management of AM572x

Other Parts Discussed in Thread: TLVH431A

We have a question about Power management of AM572x.

In datasheet p.195, Vdelta MAX = 2V.

(VDDS 18V - VDDSHVn)

(Question 1)

Please tell us the purpose of Figure 5-4. vddshv* Supplies Falling After vdds18v Supplies Delta.

Why do we have to set the Vdelta over 2V?

(Question 2)

We try to use TLVH431A to keep the voltage of Vdelta over 2.0V.

We have circuit diagram.

But we can't publish it.

Please check this circuit diagram by private e2e.

Best regards,
