3 Description

The TCAN1472-Q1 and TCAN1472V-Q1 are

high speed Controller Area Network (CAN)

SIC transceivers that meet the physical layer

requirements of the ISO 11898-2:2024 Annex A

Signal Improvement Capability (SIC) specifications.

The devices reduce signal ringing at dominant-torecessive

edge and enable higher throughput in

complex network topologies. Signal improvement

capability allows the applications to extract real

benefit of CAN FD (flexible data rate) by operating

at 2Mbps, or operating at 5Mbps or higher in large

networks with multiple unterminated stubs.

The devices meet the timing specifications mandated

by Annex A SIC part of ISO11898-2:2024; thus, have

much tighter bit timing symmetry compared to a

regular CAN FD transceivers. Providing larger timing

window to sample the correct bit, and enabling errorfree

communication in large complex star networks

where ringing and bit distortion are inherent.

These devices are pin-compatible to 8-pin CAN FD

transceivers, such as TCAN1044A-Q1 or TCAN1042-

Q1.

The TCAN1472-Q1 devices with suffix 'V' include

internal logic level translation via the VIO logic supply

terminal to allow for interfacing directly to 1.8V,

2.5V, or 3.3V controllers. The transceivers support

low power standby mode which allows remote wakeup

via CAN bus compliant with ISO 11898-2:2024

defined wake-up pattern (WUP). The device family

also includes many protection features such as

undervoltage detection, thermal shutdown (TSD),

driver dominant timeout (TXD DTO), and ±58V bus

fault protection.
