State of I2C interface on STUSB4500L when in dead-battery mode

Hi,I would like to use the STUSB4500L to power a battery powered application as well as talk to it over I2C, however since I'm running low on I2C buses I want to share the I2C bus with it and my other battery management ICs. From reading the datashee...

BlueNRG2 - New project questions

I'm starting a new SW project for a BlueNRG2 module and it's not clear what the currently preferred development toolchain is. I want to make sure I'm not using deprecated tools.The BlueNRG2 will be used as an application processor (i.e. not connected...

This question refers to the STUSB4500 reference schematic on page 26 (fig 10) of the datasheet. Will this design prevent current flowing from a secondary power source on Vsnk back to the USB connector if the secondary source's voltage is slightly higher?

In the case where USB power is first applied and a 20V contract established, the STUSB4500 would enable the power path to Vsnk as per usual. Then assume a 20.9V (for example) secondary power source is applied to the Vsnk output (say from a wall adapt...
