3 Description

The TCAN1473A-Q1 is a high-speed Controller

Area Network (CAN) transceiver that meets the

physical layer requirements of the ISO 11898-2:2023

high-speed CAN specification including the SIC

specification. The device supports both classical CAN

and CAN FD (flexible data rate) data rates up to 8

Megabits per second (Mbps).

The TCAN1473A-Q1 reduces signal ringing at the

dominant-to-recessive edge and enables higher

throughput in complex network topologies. SIC allows

the applications to extract the real benefit of CAN FD

by operating at 2Mbps, 5 Mbps, or beyond in large

networks with multiple unterminated stubs. The device

is pin compatible with classical CAN FD transceivers,

such as TCAN1043A-Q1 or TCAN1043-Q1 when

INH_MASK feature is not used (INH_MASK pin is left

floating or connected to GND).

The TCAN1473A-Q1 allows for system-level

reductions in battery current consumption by

selectively enabling the various power supplies that

can be present on a system via the INH output

pin. This allows a low-current sleep state in which

power is gated to all system components except for

the TCAN1473A-Q1, while monitoring the CAN bus.

When a wake-up event is detected, the TCAN1473AQ1

initiates system start-up by driving INH high.
