Hello,
As commented on THIS post i got a product that currently is isolated with a push pull transformer, but i am planning to change my design. I am planing to use MSP430F5508 and expose USB pins with GND and a PIN used for charging a battery (and also power the board while the battery is being charged). I considering using tpd4s014 to protect USB and VCC lines. I got a question. Is there any problem if USB lines get short circuited to GND, with each other, or with a line that power a battery charger? That probably is going to happen daily and continuously as the pads are going to be exposed and used during shower bath and inside swiming pool. The circuit i am planning to use is the same used at MSP-EXP430F5529 as it already proved to be reliable on other projects.
What else can i add to my circuit to protect USB lines?
Regards,
LR
