I would like to know absolute maximum voltage of ADP3625's OTWb terminal.
Could I have your help?
The OTW pin is usually tied to a digital line, typically 3.3V logic, with a pull-up resistor connected to it to limit the current and to absorb some voltage from the pull-up voltage. Having a pull-up voltage larger than your logic voltage could damage your microcontroller. I would like to know where you plan to use the OTW pin, this would help me understand your application and give a better answer.
