Texas Instruments TCAN1046-Q1 Fault-Protected CAN FD Transceiver

Texas Instruments TCAN1046-Q1 Fault-Protected CAN FD Transceiver 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 TCAN1046 supports classical CAN and CAN FD networks up to 8megabits per second (Mbps). The TCAN1046 has two CAN FD channels with independent supply, VCC1 and VCC2, and mode control, STB1 and STB2, pins allowing for true independent operation of each CAN channel. Operating each channel independently of one another is important in applications requiring redundancy or additional CAN FD channels to act as a backup in the event of a system failure. The Texas Instruments TCAN1046-Q1 includes many protection and diagnostic features, including thermal shutdown (TSD), TXD-dominant time-out (DTO), and bus fault protection up to ±58V.
