company blog about Long-term Stock Supply Of NXP (TJA1055T) Enhanced Fault-Tolerant CAN Transceiver Compliant with ISO 11898-2 Standard

Mingjiada Electronics offers long-term stock availability of the NXP TJA1055T—an enhanced fault-tolerant CAN transceiver fully compliant with the ISO 11898-2 standard, specifically designed for low-speed fault-tolerant communication in automotive and industrial networks.

Product Description Of TJA1055T

The TJA1055T is an upgraded version of NXP's classic TJA1054 series, pin-compatible with the TJA1054/TJA1054A, yet offering improved ESD performance, lower sleep current, and enhanced fault management. The TJA1055T operates at a maximum data rate of 125 kbps and automatically switches between single-wire and differential modes to ensure continuous bus availability. The TJA1055T is housed in a lead-free SO14 (SOT108-1) package, meets AEC-Q100 automotive certification standards, and operates within a long-term temperature range of −40 °C to +125 °C, making it an ideal choice for automotive networks and industrial fieldbus applications.

Key Parameters Of TJA1055T
• Supply voltage: 4.75 V – 5.25 V
• Bus rate: Up to 125 kbps (compliant with ISO 11898-3 low-speed fault-tolerant specification)
• Node capacity: A single bus can support up to 32 TJA1055T nodes
• Sleep current: Typical value < 10 µA, supports bus wake-up
• ESD Protection: HBM ±8 kV, IEC 61000-4-2 ±6 kV
• Package: SO14 (3.9 mm wide), compatible with reflow soldering/wave soldering
• Fault Tolerance: Can withstand CANH/L short circuits to battery or ground, supports 1.5 V ground offset

Features Of TJA1055T
• High reliability design: The TJA1055T features bus pin short-circuit protection, thermal shutdown protection, and power supply voltage undervoltage detection, ensuring stable operation in harsh environments. The TJA1055T's ESD protection capability of up to ±8 kV significantly improves system reliability.
• Fault tolerance: The TJA1055T supports fault-tolerant CAN communication rates up to 58 kbps. When a bus fault occurs, it automatically switches to single-wire mode to ensure uninterrupted communication. This feature makes the TJA1055T particularly suitable for critical applications.
• Low-power mode: The TJA1055T offers a standby mode with extremely low current consumption (typical value of 5μA), making it ideal for battery-powered devices. The TJA1055T can recover from low-power mode via local or remote wake-up.
• Electromagnetic compatibility: The TJA1055T features excellent EMC performance, meeting the most stringent testing requirements for automotive electronics. The TJA1055T's symmetrical output signals significantly reduce electromagnetic radiation.

Typical Applications Of TJA1055T
• Body Control Module (BCM): The TJA1055T provides fault-tolerant communication for low-speed CAN networks in applications such as doors, seats, and headlights.
• Heating, Ventilation, and Air Conditioning (HVAC): In HVAC systems, the TJA1055T ensures degraded operation even if the sensor and actuator bus is disconnected.
• Industrial Equipment: The TJA1055T is suitable for 24 V fieldbus applications, replacing traditional RS-485 to achieve a highly reliable multi-point network.
• Battery Management System (BMS): The TJA1055T's single-wire mode maintains communication even if the high-voltage sampling line is disconnected, enhancing system safety.
• Smart Lighting: The fault-tolerant CAN bus built using the TJA1055T ensures that even if a wiring harness short circuit occurs in a lighting fixture, it will not cause the entire network to fail.
