TCAN1462-Q1, TCAN1462V-Q1 SLLSFF2A – FEBRUARY 2022 – REVISED JUNE 2022 TCAN1462-Q1 and TCAN1462V-Q1 Automotive Fault-Protected CAN FD Transceiver with Signal Improvement Capability (SIC) and Standby Mode 1 Features 3 Description • The TCAN1462-Q1 and TCAN1462V-Q1 are high speed Controller Area Network (CAN) transceivers that meet the physical layer requirements of the ISO 11898-2:2016 high speed CAN specification and the CiA 601-4 Signal Improvement Capability (SIC) specification. 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 2 Mbps, or operating at 5 Mbps or higher in large networks with multiple unterminated stubs. • • • • • • • • AEC Q100 (Grade 1): Qualified for automotive applications Functional Safety-Capable – Documentation available to aid functional safety system design Meets the requirements of ISO 11898-2:2016 and CiA 601-4 standards Classical CAN and CAN FD up to 8 Mbps – Actively improves the bus signal by reducing ringing effects in complex topologies – Backward compatible for use in classic CAN networks VIO level shifting supports: 1.7 V to 5.5 V Operating Modes – Normal mode – Low-power standby mode supporting remote wake-up request Passive behavior when unpowered – Bus and logic terminals are high impedance (no load to operating bus or application) – Hot plug capable: power up or down glitch free operation on bus and RXD output – Defined device behavior with floating logic pins and in undervoltage supply conditions Protection features – IEC ESD protection on bus pins – ±58 V CAN bus fault tolerant – Undervoltage protection on VCC and VIO (V variants only) supply terminals – TXD dominant state timeout (TXD DTO) – Thermal shutdown protection (TSD) Available in SOIC (8), small footprint SOT-23 (8) and leadless 3mm x 3mm VSON (8) package with wettable flanks for improved automated optical inspection (AOI) capability 2 Applications • • • • • Automotive gateway Advanced driver assistance system (ADAS) Body electronics and lighting Hybrid, electric & powertrain systems Automotive infotainment & cluster The devices meet the timing specifications mandated by CiA 601-4; thus, have much tighter bit timing symmetry compared to a regular CAN FD transceivers. This provides larger timing window to sample the correct bit and enables 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 TCAN1042Q1.

The transceivers support low power standby mode which allows remote wake-up via CAN bus compliant with ISO 11898-2:2016 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 ±58 V bus fault protection. 6 Device Comparison Table 2 Device Number Bus Fault Protection Low voltage I/O Logic Support on Pin 5 Pin 8 Mode Selection TCAN1462-Q1 ± 58 V No TCAN1462V-Q1 ± 58 V Yes Low Power Standby Mode with Remote Wake Submit Document Feedback Copyright © 2022 Texas Instruments Incorporated Product Folder Links: TCAN1462-Q1 TCAN1462V-Q1 TCAN1462-Q1, TCAN1462V-Q1 www.ti.com SLLSFF2A – FEBRUARY 2022 – REVISED JUNE 2022 7 Pin Configurations and Functions TX D 1 8 STB GND 2 7 CA NH VCC 3 6 CA NL RX D 4 5 NC, VIO TXD 1 GND 2 VCC 3 RXD 4 Thermal Pad 8 STB 7 CANH 6 CANL 5 NC,VIO No t to scale Figure 7-1.
