1. Describe

TJA1043T/1J high-speed CAN transceiver provides an interface between controllers Area network (CAN) protocol controller and physical two-wire CAN bus. of The transceiver is designed for high-speed CAN applications in the automotive industry,Provides differential transmit and receive functions for microcontrollers with CAN Protocol controller. TJA1043 belongs to NXP's third-generation high-speed CAN transceiver Semiconductor, a significant improvement compared to the first and second generation Equipment, such as TJA1041A. It provides improved electromagnetic compatibility (EMC) And electrostatic discharge (ESD) performance, extremely low power consumption and It is passive when the power supply voltage is off. Advanced features include:

    1. Low-power management controls the power of the entire node, while Support local and remote wakeup by wakeup source identification

    2. Multiple protection and diagnostic functions, including bus short-circuit detection And battery connection detection

    3. Can be directly connected to a microcontroller with a supply voltage of 3 V to 5 V TJA1043 implements ISO 11898-2: 2016 and SAE J2284-1 to SAE J2284-5. This implementation is available at CAN FD fast phase, data rate up to 5 Mbit/s.

These features make TJA1043 an ideal choice for high-speed CAN networks Contains nodes that need to be always available, even if internal VIO and VCC Supplies are turned off.

2. Features

    1. Fully ISO 11898-2 and ISO 11898-5 compliant

    2. Suitable for 12 V and 24 V systems

    3. Low ElectroMagnetic Emission (EME) and high ElectroMagnetic Immunity (EMI)

    4. VIO input allows for direct interfacing with 3 V and 5 V microcontrollers

    5. SPLIT voltage output for stabilizing the recessive bus level

    6. Listen-only mode for node diagnosis and failure containment

    7. Available in SO14 and HVSON14 packages

    8. Leadless HVSON14 package (3.0 mm × 4.5 mm) with improved Automated Optical Inspection (AOI) capability

    9. Dark green product (halogen free and Restriction of Hazardous Substances (RoHS)compliant)

3. Pin configuration

4. low power management

    1. Very low current standby and sleep modes with local and remote wake-up capabilities

    2. Ability to shut down an entire node, supporting both local, remote and host wake up

    3. Wake-up source identification

    4. Transceiver disconnects from bus when VBAT is not present (zero load)

    5. Predictable functional behavior under all supply conditions

5. Protection and Diagnosis

    1. High ESD handling capability on bus pins

    2. Bus pins and VBAT protect against transients in automotive environments

    3. Transmit Data (TXD) Dominant Timeout with Diagnostics

    4. TXD to RXD short circuit handler with diagnostics

    5. Thermal protection with diagnostics

    6. Brown-out detection and recovery on VCC, VIO and VBAT pins

    7. Busbar short circuit diagnosis

    8. Bus dominant diagnosis

    9. Cold boot diagnostics (connecting the battery for the first time)
