Supply and supply monitoring

The voltages are referred to ground and currents are assumed positive, when the current

flows into the pin. Tj = -40°C to 130°C, unless otherwise specified.

IV(BAT)

Current consumption in

VBat_standby mode

(1)

Conditions for specified current consumption:

VLIN >(VS -1.5 V)

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

VWU <1V or VWU > (Vs – 1.5V)

The current consumption in standby modes with cyclic sense can be calculated using the following

formulas:

IV(BAT)CS =IV(BAT) +55µA+(2 mA *(tON + 100 µs) / T)

I(V1)CS =IV1 + 55 µA + (2 mA * (tON + 100 µs) / T)

VS = 12V; both voltage

regulators deactivated;

HS/LS driver OFF; no CAN

communication
