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.
