Hi E2E,

Good day!

Is it ok to an MCU USB signal to the BQ25886 in parallel with a USB connector?

Looking forward to your response.

Thank you and best regards,

Franz

Franz,

Are you referring to the D+/D- data lines? If so, you will need to program a 1 second delay before the MCU can begin communication over D+/D-. This 1 second delay is needed to allow the D+/D- sensing to occur. After 1 second, the charger's D+/D- pins go into Hi-Z and data communication can occur on the D+/D- lines.

Thanks,

Ricardo
