3.4.5. Vcc extra supply current in single fault condition
Compared to the quiescent current in recessive state the maximum
extra
supply current when the
CANH driver is turned on with CANH shorted to GND is needed to calculate the required worst case
Vcc buffer capacitance. This extra supply current has to be buffered for up to 6 bit times, depending
on the applications voltage regulator.
