1. General description
2. Features and benefits
2.1 General
2.2 Low-power management
2.3 Protection
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.
The TJA1049 belongs to the third generation of high-speed CAN transceivers from NXP
Semiconductors, offering significant improvements over first- and second-generation
devices such as the TJA1040. It offers improved ElectroMagnetic Compatibility (EMC)
and ElectroStatic Discharge (ESD) performance, and also features:
These features make the TJA1049 an excellent choice for all types of HS-CAN networks,
in nodes that require a low-power mode with wake-up capability via the CAN bus.
TJA1049
High-speed CAN transceiver with Standby mode
Rev. 2 — 23 March 2011
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
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)
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 V
Thermally protected
Ideal passive behavior to the CAN bus when the supply voltage is off
A very low-current Standby mode with bus wake-up capability
