Hi Team,
A customer would like to connect a 5V supply to VCCOUT to bypass the VSUP because VSUP will require another regulator with output between 6V-24v. Using 5V will simplify the design, reduce cost and save PCB space. From the datasheet, VSUP voltage should be higher than 5.5V to prevent triggering UVLO and shutdown the CAN. Will there be other complications that could happen with this design? Please refer to the block diagram below.
Regards,
Danilo
