Product data sheet
1. General description
The TJA1043 is a high-speed CAN transceiver that provides an interface between a
Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus.
The transceiver is designed for high-speed (up to 1 Mbit/s) CAN applications in the
automotive industry, providing differential transmit and receive capability to (a
microcontroller with) a CAN protocol controller.
The TJA1043 is a step up from the TJA1041A high-speed CAN transceiver. It offers
improved ElectroMagnetic Compatibility (EMC) and ElectroMagnetic Discharge (ESD)
performance, very low power consumption, and passive behavior when the supply voltage
is turned off. Advanced features include:
• Low-power management controls the power supply throughout the node while
supporting local and remote wake-up with wake-up source recognition
• Several protection and diagnostic functions including bus line short-circuit detection
and battery connection detection
• Can be interfaced directly to microcontrollers with supply voltages from 3 V to 5 V
These features make the TJA1043 the ideal choice for high speed CAN networks
containing nodes that need to be available all times, even when the internal VIO and VCC
supplies are switched off.
2. Features and benefits
2.1 General
Fully ISO 11898-2 and ISO 11898-5 compliant
Suitable for 12 V and 24 V systems
Low ElectroMagnetic Emission (EME) and high ElectroMagnetic Immunity (EMI)
VIO input allows for direct interfacing with 3 V and 5 V microcontrollers
SPLIT voltage output for stabilizing the recessive bus level
Listen-only mode for node diagnosis and failure containment
2.2 Low-power management
Very low current Standby and Sleep modes, with local and remote wake-up
Capability to power down the entire node while supporting local, remote and host
wake-up
Wake-up source recognition
Transceiver disengages from the bus (zero load) when VBAT absent
Functional behavior predictable under all supply conditions
