3 Description

The TCAN1046A-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 device supports both classical CAN and CAN FD

networks up to 8 megabits per second (Mbps). The

device 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. The ability to operate each

channel independent of one another is important in

applications that require redundancy or additional

CAN FD channels to act as a back-up in the event

of a system failure.

The device includes many protection and diagnostic

features including thermal-shutdown (TSD), TXDdominant

time-out (DTO), and bus fault protection up

to ±58 V. The device has defined failsafe behavior in

supply under-voltage or floating pin scenarios.
