3.4. Average Supply Current at Presence of a Short-Circuit of one Bus Wire
The maximum Vcc supply current occurs with a bus wire short-circuit between CANH and GND. In this
case the CANH outputs a maximum short circuit current in dominant state (see data sheets). For
thermal considerations the average supply current is relevant. For buffering considerations the
maximum dominant supply current is relevant.

The 6-bit time limitation is caused by a supposed Error Flag to be sent by the CAN Controller.

3.4.3. Thermal considerations (with CANH shorted to GND)
For thermal considerations the average supply current at pin Vcc is relevant considering the transmit
duty cycle. With a transmit duty cycle of 50% on pin TxD, the maximum average supply current at
CANH to GND short-circuit is:
I
cc_sc1_avg
= 0.5 * (I

:
I
cc_sc1_avg 1053
= 0.5 * (10mA + 139mA) =
74.5 mA max.
(Ex 5.2)
TJA1054
:
I
cc_sc1_avg 1054
= 0.5 * (11mA + 141mA) =
76 mA max.
