TPS65987D: Cannot negotiate with Samsung travel adapter (EP-TA845)

Part Number: TPS65987D
Other Parts Discussed in Thread: TPS65988EVM, , TPS65987EVM

Hi, everyone,

Now we noticed this problem, when we use "Samsung Travel adapter (EP-TA845)."

Its PDOs are:
(PPS) 3.3-11.0V==4.05A
(PPS) 3.3-16.0V==2.8A
(PPS) 3.3-21.0V==2.1A

As our products (PCs) are designed so that they don't support PPS,
when we attached its adapter,
TPS65987DDH should request 20V==2.25A (i.e. ask for max).

But when Samsung adaptor send SouceCap, TPS65987DDH do soft reset...

Why is it ?

We'll attach PD analyzer data caption
and send data to your colleague Yone-san.

And our base FW ver. is F707.10.05 & F707.10.06.

Best Regards,
