The TCAN1042 and TCAN1051 CAN transceiver families claim the best combination of protection and high performance for a variety of automotive and industrial applications. Features include:
- Compliance with EMC standards; the 16 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.
- Common-mode choke removal: the devices eliminate the need for an external noise-suppressing 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: protection up to 70V 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.
- Shortest loop delay of 175 nsec enables more margin in the system design, longer networks and more nodes on the CAN bus.
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.
An evaluation module (EVM), TCAN1042DEVM costs $49; the TCAN1042 and TCAN1051 families of 24 eight-pin CAN transceivers start at $0.48 (1000).
