The TCAN1043A-Q1 is powered through the VSUP, VCC, and VIO supply pins via the EVM. Each supply pin must be connected to the appropriate supply voltage. VSUP can be connected to an automotive battery voltage directly with a reverse blocking diode and supports voltages from 4.5 V to 40 V. Banana jack P4 is used to connect this voltage to the EVM, use TP13 to monitor this voltage. VCC is the supply voltage and supports voltages from 4.5 V to 5.5 V. Banana jack P1 is used to connect this voltage to the EVM, monitor this voltage with TP11. VIO is the I/O supply voltage and supports voltages from 1.7 V to 5.5 V. Banana jack P2 is used to connect this voltage to the EVM, monitor this voltage with TP12.
