3 Description

The TCAN1044AEV-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 transceiver has a certified electromagnetic compatibility (EMC) operation making it a suitable choice for classical CAN and CAN FD networks up to 5 megabits per second (Mbps). Up to 8 Mbps operation in simpler networks is possible with these devices. The device includes internal logic level translation via the VIO pin 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 transceiver supports a low-power standby mode and wake over CAN which is compliant to the ISO 11898-2:2016 defined wake-up pattern (WUP).

The transceiver also includes thermal-shutdown (TSD), TXD-dominant time-out (DTO), supply undervoltage detection, and ±58-V bus fault protection. The device has defined fail-safe behavior in supply undervoltage or floating pin scenarios.
