3 Description

The TCAN1472-Q1 devices are high speed Controller

Area Network (CAN) SIC transceiver 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-to-recessive 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, 5Mbps or higher in large

networks with multiple unterminated stubs.

The devices meet the timing specifications mandated

by ISO 11898-2:2024 Annex A SIC specifications, and

thus have much tighter bit timing symmetry compared

to a regular CAN FD transceivers. This provides a

larger timing window to sample the correct bit, and

enables error-free 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.
