TI chokeless high-speed CAN transceiver

Texas Instruments (TI) introduced two families of controller area network (CAN) transceivers that meet all industry requirements for electromagnetic compatibility (EMC) from U.S. and European automotive manufacturers. Delivering high bus-fault protection, fast CAN flexible data rate (FD) speeds and the industry’s shortest loop delay, the TCAN1042 and TCAN1051 CAN transceiver families provide the industry’s best combination of protection and high performance for a variety of automotive and industrial applications.

Key features and benefits of the new CAN transceiver families:

• Compliance with EMC standards from leading international organizations: The 16 Automotive Electronics Council (AEC) Q100-qualified devices meet EMC requirements for automobile manufacturers in the United States (Society of Automotive Engineers [SAE] J2962) and Europe (Ingenieurbüro für Industrielle Elektrotechnik [IBEE]-Zwickau). The eight industrial devices meet the requirements of the Comité International Spécial des Perturbations Radioélectriques (CISPR) 22, International Electrotechnical Commission (IEC) 61000-4-6 up to 10 V, IEC 61000-4-4 Criteria A to ±4 kV, and IEC 61000-4-3 from 80 MHz to 2.7 GHz up to 100 V/meter.
• Enables common-mode choke removal: The devices eliminate the need for an external noise-suppressant common-mode choke component, thereby reducing bill-of-materials cost and space in automotive and industrial designs.
• High bus-fault and electrostatic discharge (ESD) protection: High bus-fault protection up to 70 V exceeds 12-, 24- and 48-V battery requirements, in addition to protecting against 24-V DC industrial power supplies. This protects CAN bus pins against short-to-DC voltages. ESD protection up to ±15 kV eliminates the need for external transient voltage suppression (TVS) diodes, saving board space and cost.
• Increased bandwidth: A fast CAN FD speed of up to 5 Mbps increases the communication speed and data-transfer capability between electronic control units and nodes on the CAN network.
• Industry-leading flexibility: The industry’s shortest loop delay of 175 ns enables more margin in the system design, longer networks and more nodes on the CAN bus.

Tools and support to speed design

Engineers can quickly and easily evaluate the performance of the TCAN1042 and TCAN1051 families with an evaluation module (EVM). The TCAN1042DEVM is available today for US$49 from the TI store and authorized distributors.

Package, availability and pricing

The TCAN1042 and TCAN1051 families of 24 eight-pin CAN transceivers are available today in 1,000-unit quantities starting at US$0.48. TCAN1042 devices contain a standby mode with a bus wake-up feature and variations for fault protection, bit rate and level-shifting. TCAN1051 devices include a silent mode and variations for fault protection, bit rate and level-shifting.
