General description
The TJA1049 high-speed CAN transceiver 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, supplying the differential transmit and receive capability to (a microcontroller with) a CAN protocol controller.

FEATUREs and benefits
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)
◾ SPLIT voltage output for stabilizing the recessive bus level

Low-power management
◾ Very low-current Standby mode with host and bus wake-up capability
◾ Functional behavior predictable under all supply conditions
◾ Transceiver disengages from the bus when not powered up (zero load)

Protection
◾ High ESD handling capability on the bus pins
◾ Bus pins protected against transients in automotive environments
◾ Transmit Data (TXD) dominant time-out function
◾ Bus-dominant time-out function in Standby mode
◾ Undervoltage detection on pin VCC
◾ Thermally protected
