3 Description

The TCAN1043A-Q1 is a high-speed Controller Area

Network (CAN) transceiver that meets the physical

layer requirements of the ISO 11898-2:2016 highspeed

CAN specification. The device supports both

classical CAN and CAN FD data rates up to 8

megabits per second (Mbps) (TCAN1043A-Q1) or 5

Mbps (TCAN1043AT-Q1).

The TCAN1043A-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 low-current sleep state in which

power is gated to all system components except for

the TCAN1043A-Q1, while monitoring the CAN bus.

When a wake-up event is detected, the TCAN1043AQ1

initiates system start-up by driving INH high.

The TCAN1043A-Q1 features an SWE timer that

enables a safe transition to Sleep mode after 4

minutes (tINACTIVE) of inactivity in Standby mode. This

makes sure the device is transitioned to low-power

Sleep mode if the MCU fails to transition the device to

Normal mode.
