Our design looks to use USB power adapter for charging a single cell lithium ion battery. Is it necessary to route the differential pair at a controlled impedance to the D+/D- pins if only used for power delivery? We do not intend to have a microprocessor connected to the D+/D- lines.
I believe the answer is no it is not necessary, and these signals could be routed as 'static' signals, but I would like to confirm.
Thanks,
Daniel
