SLLSFL8A July 2021 – December 2021 TCAN1046AV-Q1 , TCAN1048AV-Q1
PRODUCTION DATA
The TCAN1046AV-Q1 and TCAN1048AV-Q1 (TCAN104xAV-Q1) are dual, high-speed controller area network (CAN) transceivers that meet the physical layer requirements of the ISO 11898-2:2016 high-speed CAN specification.
The TCAN104xAV-Q1 transceivers support both classical CAN and CAN FD networks up to 8 megabits per second (Mbps). The device includes internal logic level translation via the VIO terminal to allow for interfacing the transceiver I/O's directly to 1.8-V, 2.5-V, 3.3-V, or 5-V logic levels.
The two CAN channels support independent mode control through the standby pins. Therefore, each transceiver can be placed into a low-power state, standby mode, without impacting the state of the other CAN channel. While in standby mode, the device supports remote wake-up pattern via the CAN bus which is compliant to the ISO 11898-2:2016 defined wake-up pattern (WUP).

The transceivers also include many protection and diagnostic features including thermal-shutdown (TSD), TXD-dominant time-out (DTO), supply undervoltage detection, and bus fault protection up to ±58 V. The devices have defined failsafe behavior in supply undervoltage or floating pin scenarios.
