Product Description

Overview
The TJA1046 is a dual high-speed CAN transceiver that provides two interfaces between a Controller Area Network (CAN) protocol controller and the physical two-wire CAN-bus. It is composed of two fully independent TJA1044GT transceivers. The transceivers are designed for high-speed CAN applications in the automotive industry, providing the differential transmit and receive capability to (a microcontroller with) a CAN protocol controller. The TJA1046 guarantees robust communication at data rates up to 5 Mbit/s as used in, for example, CAN FD networks.
The TJA1046 offers a feature set optimized for 12 V automotive applications and excellent ElectroMagnetic Compatibility (EMC) performance.
Additionally, the TJA1046 features:
* Ideal passive behavior to the CAN-bus when the supply voltage is off
* A very low-current Standby mode with bus wake-up capability
* Excellent EMC performance at speeds up to 500 kbit/s, even without a common mode choke
The HVSON package allows for more than 70 % PCB space saving compared with traditional SO packages. These features make the TJA1046 an excellent choice for networks containing more than one HS-CAN interface requiring a low-power mode with wake-up capability via the CAN-bus, especially for body and gateway control units.
The TJA1046 implements the CAN physical layer as defined in the current ISO11898 standard (ISO11898-2: 2003, ISO11898-5: 2007 and the pending updated version of ISO 11898-2:2016). 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.

## Features
### General
* Two fully independent TJA1044GT HS-CAN transceivers combined in a single package
* Fully ISO 11898-2:2003 and ISO 11898-5:2007 compliant
* Timing guaranteed for data rates up to 5 Mbit/s
* Improved TXD to RXD propagation delay of 210 ns
* Very low-current Standby mode with host and bus wake-up capability
* Optimized for use in 12 V automotive systems
* EMC performance satisfies "Hardware Requirements for LIN, CAN and FlexRay Interfaces in Automotive Applications’, Version 1.3, May 2012.
* Leadless HVSON14 package (3.0 mm × 4.5 mm) with improved Automated Optical Inspection (AOI) capability
* Can interface with 3.3 V and 5 V-supplied microcontrollers, provided the microcontroller I/Os are 5 V tolerant
