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 V IO 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 TCAN1043xx-Q1 meets the ESD and EMC requirements of IEC
62228-3 and J2962-2 without the need for additional protection components.
