TJA1466CHG/0J

Drivers, Receivers, Transceivers Overview

The TJA1466CHG/0J is a high-speed CAN transceiver implementing the ISO 11898-2:2024 physical layer with CAN Signal Improvement Capability (SIC). It supports data rates up to 8 Mbit/s and features partial networking via selective wake-up. The device includes two configurable GPIO pins, an SPI interface for configuration, and a Q&A watchdog. It achieves ASIL B compliance per ISO 26262. The 'C' suffix indicates support for a 5 V VIO supply. It operates within a battery voltage range of 4.75 V to 40 V and a junction temperature range of -40 °C to +150 °C.

Drivers, Receivers, Transceivers Feature Summary

• Implements CAN signal improvement capability (SIC) to reduce signal ringing in complex topologies.
• Supports partial networking through selective wake-up functionality for low-power management.
• Includes advanced system monitoring with undervoltage detection and overtemperature protection.
• Features configurable general-purpose I/O pins and an SPI interface for diagnostics.

Drivers, Receivers, Transceivers Applications

• Automotive networks requiring ISO 26262 ASIL B compliance
• High-speed CAN FD communication systems operating at bit rates up to 8 Mbit/s
• Complex network topologies where signal integrity enhancement is required

Drivers, Receivers, Transceivers Procurement Notes

Verify that the ordering suffix matches the required VIO supply level; the 'C' variant specifically supports 5 V logic levels. Confirm package type DHVQFN18 availability and ensure the specific revision aligns with design requirements. Cross-reference the manufacturer's latest documentation for any updates to the RoHS status or pin configurations before finalizing procurement.

Drivers, Receivers, Transceivers Selection Notes

Select this component when ASIL B functional safety certification is mandatory for the CAN interface. Ensure the host microcontroller operates at 5 V logic levels to match the TJA1466C specification. Verify that the application requires SIC features for high-speed stability or partial networking capabilities for power optimization. Check compatibility with existing SPI diagnostic implementations.

Drivers, Receivers, Transceivers Part Context

This part belongs to the TJA1466x family of CAN SIC transceivers. It is designed as a pin-compatible replacement for conventional HS-CAN transceivers, facilitating upgrades to higher speeds and improved signal integrity without major PCB redesigns. It complements other NXP automotive interface solutions like the TJA1465 series.

Drivers, Receivers, Transceivers Replacement Considerations

Publicly confirmed substitutes include TJA1465BHG/0J and TJA1466AHG/0J. Note that TJA1465 variants lack the advanced system monitoring features present in the TJA1466. TJA1466A offers identical functionality but requires a 1.8 V VIO supply instead of 5 V.
