Hello -
The datasheet says that the PDB pin has an internal pulldown, which means if PDB is not driven externally the DS90UB913Q-Q1 will be in shutdown mode. I need to know what the value of that internal pulldown is, because I need the device to be "on" by default, but do not want to tie it directly to VDDIO (it's complicated, but there are circumstances under which I still want to be able to shut down or reset the DS90UB913Q-Q1 with PDB). The DS90UB953 datasheet says 1M, but couldn't find anything for the 913. Thank you
