TJA1043T,118

TJA1043 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:

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

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

• 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.
