TJA1468: Dual-Channel CAN SIC Transceiver with Standby Mode (ASIL B)
- This page contains information on a preproduction product. Specifications and information herein are subject to change without notice. For additional information please contact your sales representative.
The TJA1468 is a dual-channel controller area network signal improvement capability (CAN SIC) transceiver with standby mode, designed for high-speed automotive and industrial CAN networks. Fully compliant with ISO 11898-2:2024 and SAE J2284-1 through J2284-5, it minimizes signal ringing to ensure reliable CAN flexible data-rate (CAN FD) communication at 5 Mbit/s and supports data rates up to 8 Mbit/s in larger or more complex topologies.
Compared with two single-channel SIC transceivers, the TJA1468 reduces overall system cost and bill-of-materials (BOM) size while providing ASIL B functional safety and bus-load capability compatible with AN extra long (CAN XL). It is a direct drop-in replacement for NXP's TJA1448, enabling an easy upgrade path for existing CAN and CAN FD designs.
Product Details
Features
Core Capabilities
- Compliant with ISO 11898-2:2024, SAE J2284-1 to SAE J2284-5 and SAE J1939-14
- Supports CAN FD communication up to 8 Mbit/s
- Includes a voltage input/output (VIO) input for interfacing with 3.3 V to 5 V microcontroller (MCU) (compatible with TJA1448)
- Low electromagnetic emission (EME) and high electromagnetic immunity (EMI)
- Qualified according to AEC-Q100 Grade 1
- Available in SO14 package and leadless HVSON14 package, much smaller BOM than 2x single CAN SIC
CAN SIC/CAN XL Readiness
- Implements CAN SIC as defined in ISO 11898-2:2024, third edition, to significantly reduce signal ringing effects on a network
- Provides tighter bit timing symmetry performance, allowing more times to reduce signal ringing
- Shortens maximum wake-up-pattern time to 1.45 µs
- Extends the bus-load range from 45 Ω to 65 Ω to support both CAN SIC and CAN XL fast mode
Fail-Safe and Functional Safety
- Designed to support ASIL B according to ISO 26262, providing all required functional safety documentation, such as safety manual and failure modes, effects and diagnostic analysis (FMEDA)
- Includes undervoltage detection with defined handling on all supply pins
- Guarantees full functionality from the undervoltage detection thresholds up to the maximum limiting voltage values
- Defines behavior below the undervoltage detection thresholds
- Transceiver disengages from the bus (high-ohmic) when the supply voltage drops below the off-mode threshold
- Includes internal biasing of transmit data (TXD) and mode-selection input pins to enable defined fail-safe behavior
