3 Description

The TCAN1473-Q1 is a Controller Area Network

(CAN) transceiver that meets the physical layer

requirements of the ISO 11898-2:2024 CAN

specification with Signal Improvement Capability (SIC)

functionality. The device reduces signal ringing at

dominant-to-recessive edges and enables higher

throughput in complex network topologies. SIC allows

applications to extract the real benefit of CAN Flexible

Datarate (CAN FD) by operating at 2Mbps, 5Mbps,

and 8Mbps, even in large networks with multiple

unterminated stubs.

The TCAN1473-Q1 allows for system-level reductions

in battery current consumption by selectively enabling

the various power supplies that may be present on

a system via the INH output pin. This allows a lowcurrent

sleep state in which power is gated to all

system components except for the TCAN1473-Q1,

while monitoring the CAN bus. When a wake-up event

is detected, the TCAN1473-Q1 initiates system startup

by driving INH high.

These devices are pin-compatible to 14-pin singlechannel

CAN FD transceivers, such as TCAN1043NQ1

or TCAN1043H-Q1.
