I would use ADP5062 for several power supply configuration. In one of this it should let pass power even if battery is not connected. This don't occour with DIG_IO1=low DIG_IO2=low DIG_IO3=high (to ISO_Bx via 10k res). Am I wrong in configuration? Doing so just 1.4V appears at ISO_Sx with 5V at VINx and w/o battery connected. While connecting a battery (even for a short time) allo 5V to be present (and persist when battery is disconnected while VINx hold) at ISO_Sx.

 

Thamk you in advance
