Texas Instruments TCAN1463-Q1 High-Speed CAN FD Transceiver
Texas Instruments TCAN1463-Q1 High-Speed Controller Area Network (CAN) FD Transceiver meets the physical layer requirements of the ISO 11898-2:2016 high-speed CAN specification and the CiA 601-4 SIC specification. The device supports classical CAN and CAN FD (flexible data rate) data rates up to 8Megabits per second (Mbps). The TCAN1463-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, 5Mbps, 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 the INH_MASK feature is not used (INH_MASK pin is left floating or connected to GND).
The Texas Instruments TCAN1463-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 feature allows a low-current sleep state in which power is gated to all system components except for the TCAN1463-Q1 while monitoring the CAN bus. When a wake-up event is detected, the TCAN1463-Q1 initiates system start-up by driving INH high. The TCAN1463-Q1 features an SWE timer that enables a safe transition to Sleep mode after 4 minutes (tINACTIVE) of inactivity in Standby mode. This feature ensures that the device is transitioned to low-power Sleep mode if the MCU fails to transition the device to Normal mode.
