Hi,
Is there any information regarding whether there are internal clamping diodes to VDD and GND on the open-drain outputs (RP_1A5, RP_3A, ATTACH, ALERT, A_B_SIDE, GPIO) of the STUSB4500L device?
If these outputs have external pull-up resistors that connect to a separate 3.3V supply that is always ON, and the STUSB4500L is off when the USB is disconnected (the device is powered by USB VBUS), what leakage currents can we expect to flow into the device?
