1. Conditions for specified current consumption:

•

VLIN > (VSREG - 1.5 V)

•

(CAN_H - CAN_L) < 0.4 V or (CAN_H - CAN_L) > 1.2 V

•

VWU < 1 V or VWU > (VSREG - 1.5 V)

•

LIN wake-up is possible, CAN wake up disabled, WUx_EN register set to 0

2. In SPSB081Cx it is mandatory to keep wake-up source capability (CANFD or wake-up pin) and in that case an additional

contribution of IV(VBAT_WU,x) or IV(CANWU,x) has to be considered.

3. Guaranteed by design.

4. Current consumption adders of features defined for SBC V1 stby mode or for SBC VBAT stby mode (unless otherwise

specified).

5. Current consumption adder while only one HS is turned on with no load.

5.1

Oscillator

The voltages are referred to ground and currents are assumed positive, when the current flows into the pin.

6 V ≤ VS ≤ 28 V; 6 V ≤ VSREG ≤ 28 V; TJ = -40 °C... 150 °C, unless otherwise specified.
