3 Description

The TCAN3403-Q1 and TCAN3404-Q1 are 3.3 V

controller area network (CAN) FD transceivers that

are compatible with the physical layer requirements of

the ISO 11898-2:2016 high-speed CAN specification.

The transceivers have certified electromagnetic

compatibility (EMC) operation for use with 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 TCAN3403-Q1 includes an internal logic level

translation through the VIO pin, allowing the direct

interface of the transceiver I/Os to 1.8-V, 2.5-V, or

3.3-V logic levels. The TCAN3404-Q1 has shutdown

feature where all blocks are powered off and device

enters ultra-low power consumption mode. The

transceivers support a low-power standby mode, and

a wake over CAN which is compliant to the ISO

11898-2:2016 defined wake-up pattern (WUP).

The transceivers include thermal-shutdown (TSD),

TXD-dominant time-out (DTO) and supply

undervoltage detection. The devices have defined

fail-safe behavior in supply undervoltage or floating

pin scenarios. These devices are available in industrystandard

SOIC-8, the VSON-8, and a space-saving

small footprint SOT-23 packages.
