3 Description

The TCAN1046V-Q1 is a dual, high-speed controller area network (CAN) transceiver that meets the physical layer requirements of the ISO 11898-2:2016 high-speed CAN specification.

The TCAN1046V-Q1 transceiver supports both classical CAN and CAN FD networks up to 8 megabits per second (Mbps). The TCAN1046V-Q1 includes internal logic level translation via the VIO terminal to allow for interfacing the transceiver IOs directly to 1.8 V, 2.5 V, 3.3 V, or 5 V logic IOs. The two CAN channels support independent mode control through the standby pins. This provides the ability to place each transceiver into its low-power state, standby mode, without impacting the state of the other CAN channel. While in standby mode the TCAN1046V-Q1 supports remote wake-up via the ISO 11898-2:2016 defined wake-up pattern (WUP). The TCAN1046V-Q1 transceivers also include many protection and diagnostic features including thermal shutdown (TSD), TXD dominant timeout (DTO), supply undervoltage detection, and bus fault protection up to ±58 V.
