Product Description

Overview
The TJA1043 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 CAN applications in the automotive industry, providing differential transmit and receive capability to (a microcontroller with) a CAN protocol controller.
The TJA1043 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 TJA1041A. 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
The TJA1043 implements the CAN physical layer as defined in the current ISO11898 standard (ISO11898-2:2003, ISO11898-5:2007 and the pending updated version of ISO11898-2:2016). Pending the release of ISO11898-2:2016 including CAN FD and SAE-J2284-4/5, additional timing parameters defining loop delay symmetry are specified. This implementation enables reliable communication in the CAN FD fast phase at data rates up to 5 Mbit/s.
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.

## Features
### General
* Fully ISO 11898-2:2003 and ISO 11898-5:2007 compliant
* Loop delay symmetry timing enables reliable communication at data rates up to 5 Mbit/s in the CAN FD fast phase
* 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
* Available in SO14 and HVSON14 packages
* Leadless HVSON14 package (3.0 mm × 4.5 mm) with improved Automated Optical Inspection (AOI) capability
* AEC-Q100 qualified
* Dark green product (halogen free and Restriction of Hazardous Substances (RoHS) compliant)
### 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
### Protection and diagnosis (detection and signalling)
* High ESD handling capability on the bus pins
* Bus pins and VBAT protected against transients in automotive environments
* Transmit Data (TXD) dominant time-out function with diagnosis
* TXD-to-RXD short-circuit handler with diagnosis
* Thermal protection with diagnosis
* Undervoltage detection and recovery on pins VCC, VIO and VBAT
* Bus line short-circuit diagnosis
* Bus dominant clamping diagnosis
* Cold start diagnosis (first battery connection)
