TCAN1472-Q1

The TCAN1472-Q1 and TCAN1472V-Q1 are high speed Controller Area Network (CAN) SIC transceivers that meet the physical layer requirements of the ISO 11898-2:2024 Annex A Signal Improvement Capability (SIC) specifications. The devices reduce signal ringing at dominant-to-recessive edge and enable higher throughput in complex network topologies. Signal improvement capability allows the applications to extract real benefit of CAN FD (flexible data rate) by operating at 2Mbps, or operating at 5Mbps or higher in large networks with multiple unterminated stubs.

The devices meet the timing specifications mandated by Annex A SIC part of ISO11898-2:2024; thus, have much tighter bit timing symmetry compared to a regular CAN FD transceivers. Providing larger timing window to sample the correct bit, and enabling error-free communication in large complex star networks where ringing and bit distortion are inherent.

These devices are pin-compatible to 8-pin CAN FD transceivers, such as TCAN1044A-Q1 or TCAN1042-Q1.

The TCAN1472-Q1 devices with suffix ’V’ include internal logic level translation via the VIO logic supply terminal to allow for interfacing directly to 1.8V, 2.5V, or 3.3V controllers. The transceivers support low power standby mode which allows remote wake-up via CAN bus compliant with ISO 11898-2:2024 defined wake-up pattern (WUP). The device family also includes many protection features such as undervoltage detection, thermal shutdown (TSD), driver dominant timeout (TXD DTO), and ±58V bus fault protection.
