Description:

The TCAN1044-Q1 is a high-speed Controller Area Network (CAN) transceiver that meets the physical layer requirements of the ISO 11898-2:2016 high-speed CAN specification. The TCAN1044-Q1 transceiver supports both classical CAN and CAN FD networks (data rates up to 8 megabits per second (Mbps)). The TCAN1044V-Q1 includes internal logic level translation via the VIO pin, allowing the transceiver I/O to be connected directly to 1.8V, 2.5V, 3.3V, or 5V logic levels. These transceivers support a low-power standby mode and can be woken up via CAN in accordance with the wake-up pattern (WUP) defined in ISO 11898-2:2016. In addition, the TCAN1044-Q1 transceiver includes protection and diagnostic features supporting thermal shutdown (TSD), TXD dominant timeout (DTO), supply undervoltage detection, and bus fault protection up to ±58V.
