Battery Fail
Turn OFF
Turn OFF due to V2.
No communication

No change
VDD Over-temperature
Turn OFF
Turn OFF due to V2.
No communication
OFF
VDD Over-current
VDD regulator enters linear
mode. VDD under-voltage
reset may occurs. VDD

warning or shutdown may
occur
Turn OFF if VDD under-
voltage reset occurs
If V2 is OFF, turn OFF
and no communication
Turn OFF if VDD under-
voltage reset occurs
VDD Short-circuit

Notes
49.
Refer to descriptions of CANH and CANL short to GND, VDD, and VSUP elsewhere in table.
50.
Peak current 150 mA during TXD dominant only. Due to loss of communication, CAN controller reaches bus OFF state. Average current
out of V2 is below 10 mA.
51.
Over-current might be detected. THERM-CUR bit set in CAN register.
