3 Description

The TCAN1476-Q1 is a dual, high speed Controller

Area Network (CAN) SIC transceiver that meets the

physical layer requirements of the ISO 11898-2:2024

Annex A Signal Improvement (SIC) specification.

The device reduces signal ringing at dominant-torecessive

edge and enables higher throughput in

complex network topologies. Signal improvement

capability allows the applications to extract real

benefit of CAN FD (flexible data rate) by being able

to operate at 2Mbps, 5Mbps or even beyond in large

networks with multiple unterminated stubs.

The device meets the timing specifications mandated

by ISO 11898-2:2024 Annex A SIC mode

specifications; thus, has much tighter bit timing

symmetry compared to regular CAN FD transceivers.

This provides 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.

This device is pin-compatible to 14-pin dual

CAN FD transceivers, such as TCAN1046A-Q1 or

TCAN1046AV-Q1.

The TCAN1476-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 two CAN channels support

independent mode control through the standby pins.

Therefore, each transceiver can be placed into a

low-power state, standby mode, without impacting

the state of the other CAN channel. The low power

standby mode allows remote wake-up via CAN

bus compliant with ISO 11898-2:2024 defined wakeup

pattern (WUP). The device also includes many

protection features such as undervoltage detection,

thermal shutdown (TSD), driver dominant timeout

(TXD DTO), and ±58V bus fault protection.
