9.3.3 Undervoltage Lockout

The supply terminals have undervoltage detection that places the device in protected mode. This protects the bus during an undervoltage event on either the VCC or VIO supply terminals.

(1) See the VIT section of the Electrical Characteristics.
(2) Mirrors bus state: low if CAN bus is dominant, high if CAN bus is recessive.

(2) Refer to Section 9.4.3.1
Note:

After an undervoltage condition is cleared and the supplies have returned to valid levels, the device typically resumes normal operation within 50 µs.
