CAN FD transceivers

With data rates up to 5 Mbit/s

Texas Instruments' (TI) CAN transceivers solve specialized networking requirements for various applications and power supply systems. They provide solutions for 5-V and 3,3-V operation, as well as CAN FD.

The portfolio of CAN transceivers includes for example devices with multiple operating voltages, automotive and industrial grades, multiple power modes, optimized loop times, or integrated galvanic isolation. Additionally, a 3,3 V CAN transceiver, an isolated transceiver, and CAN FD-capable ones are available.

The TCAN33x family is compatible with the ISO 11898 CAN physical layer standard. The TCAN330, TCAN332, TCAN334, and TCAN337 are specified for data rates up to 1 Mbit/s. For the TCAN330G, TCAN332G, TCAN334G, and TCAN337G devices, data rates up to 5 Mbit/s are available since they support CAN FD. Additionally, timing parameters defining loop delay symmetry are specified. This series includes protection features such as driver and receiver Dominant Time Out (DTO) providing CAN network robustness. An integrated 12-kV IEC-61000-4-2 ESD Contact Discharge protection eliminates the need of additional components.

The use of the single 3,3-V supply enables the transceivers to directly interface with 3,3-V CAN controllers/MCUs. In addition, these devices are fully compatible with other 5-V CAN transceivers on the same bus. These devices come with matched Dominant and Recessive common modes for EMC performance. The Shutdown and Standby modes make these devices attractive for battery powered applications. This transceiver series is available in 8-pin SOIC packages for drop-in compatibility and in SOT-23 packages for space-constrained applications. CANopen, Devicenet, NMEA 2000, Arinc 825, Isobus, and CANaerospace are supported.

Another added product is the TCAN1042x transceiver family which also meets the ISO1189-2 physical layer standard. All of the devices are designed for use in CAN FD networks up to 2 Mbit/s. Devices with part numbers that include the “G” suffix are designed for data rates up to 5 Mbit/s, and versions with the “V” have a secondary power supply input for I/O level shifting the input pin thresholds and RXD output level. This family has a low power standby mode with remote wake request feature. Additionally, all devices include protection features to enhance device and CAN network robustness. The transceivers have an operating temperature of -55 °C to +125 °C and support the same protocols as mentioned above.
