TCAN1043DMTRQ1

The TCAN1043xx-Q1 meets the physical layer
requirements of the ISO 11898–2 (2016) High
Speed Controller Area Network (CAN) specification
providing an interface between the CAN bus and
the CAN protocol controller. These devices support
both classical CAN and CAN FD up to 2 megabits
per second (Mbps). Devices with part numbers
that include the suffix “G” are designed for CAN
FD data rates up to 5Mbps. The TCAN1043xx-Q1
allows for system-level reductions in battery current
consumption by selectively enabling (via the INH
output pin) the various power supplies that can be
present on a node. This allows an ultra-low-current
sleep state in which power is gated to all system
components except for the TCAN1043xx-Q1, which
remains in a low-power state monitoring the CAN bus.
When a wake-up pattern is detected on the bus or
when a local wake-up is requested via the WAKE
input, the TCAN1043xx-Q1 initiates node start-up
by driving INH high. The TCAN1043xx-Q1 includes
internal logic level translation via the VIO terminal to
allow for interfacing directly to 3.3 V or 5 V controllers.
The device includes many protection and diagnostic
features including CAN bus line short-circuit detection
and battery connection detection. The TCAN1043xxQ1 meets the ESD and EMC requirements of IEC
62228-3 and J2962-2 without the need for additional
protection components.
