The basic setup of the TCAN1046A/V EVM uses at most two power supply outputs required to evaluate a standard 5-V supply transceiver with the possibility of 3.3-V IO level device performance. For VCC the power supplied should meet 5-V and at least 100-mA. For the TCAN1046A footprint connect the 5-V supply to the J6. For the TCAN1046AV footprint connect the 5-V supply to the J21.
