Characteristics noted under conditions 5.5 V

≤ VSUP ≤ 28 V, -40 °C ≤ TA ≤ 125 °C, unless otherwise noted. Typical values

noted reflect the approximate parameter means at TA = 25 °C under nominal conditions, unless otherwise noted.

Notes

All parameters in spec (ex: VDD regulator tolerance).

10.

Device functional, some parameters could be out of spec. VDD is active, device is not in Reset Mode if the lowest VDD under-voltage

reset threshold is selected (approx. 3.4 V). CAN and I/Os are not operational.

11.

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.

12.

VSUP1 and VSUP2 supplies are internally connected on part number MC33903BDEK and MC33903BSEK. Therefore, ISUP1 and ISUP2

cannot be measured individually.
