Notes
15.
All parameters in spec (ex: VDD regulator tolerance).
16.
Device functional, some parameters could be out of spec. VDD is active, device is not in Reset mode if the lowest VDD undervoltage reset
threshold is selected (approx. 3.4 V). CAN and I/Os are not operational.
17.
In Run mode, CAN interface in Sleep mode, 5 V-CAN and VAUX turned OFF. IOUT at VDD < 50 mA. Ballast: turned OFF or not connected.
18.
VSUP1 and VSUP2 supplies are internally connected on part number MC33903BDEK and MC33903BSEK. Therefore, ISUP1 and ISUP2
cannot be measured individually.
