In the Cypress 45W Car Charger reference design, U4-16 (DP0) is tied to C-D- and U4-17 (DM0) to C-D+.  These look reversed.  Please advise.

Thanks,

Byron

Hi,

It's not reversed. Pin 17 of CCG3PA should be DP/P3.0. Pin 16 should be DM0/P3.1(See datasheet). The label of the component used in this schematic is not correct.

Regards,

Eddie
