TJA1145  
High-speed CAN transceiver for partial networking  
Rev. 1 — 27 September 2013  
Product data sheet  
1. General description  
The TJA1145 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 CAN applications in the automotive industry,  
providing differential transmit and receive capability to (a microcontroller with) a CAN  
protocol controller.  
The TJA1145 features very low power consumption in Standby and Sleep modes and  
supports ISO 11898-6 compliant CAN Partial Networking by means of a selective wake-up  
function.  
A dedicated implementation of the partial networking function has been embedded into  
the TJA1145/FD variants TJA1145T/FD and TJA1145TK/FD (see Section 6.3.1 for further  
details on CAN FD). This function is called ‘FD-passive’ and is the ability to ignore CAN  
FD frames while waiting for a valid wake-up frame in Sleep/Standby mode. This additional  
feature of partial networking is the perfect fit for networks that support both CAN FD and  
standard CAN 2.0 communications. It allows normal CAN controllers that do not need to  
communicate CAN FD messages to remain in partial networking Sleep/Standby mode  
during CAN FD communication without generating bus errors.  
Advanced power management regulates the supply throughout the node and supports  
local and remote wake-up functionality. I/O levels are automatically adjusted to the I/O  
levels of the controller, allowing the TJA1145 to interface directly with 3.3 V to 5 V  
microcontrollers. An SPI interface is provided for transceiver control and for retrieving  
status information. Bus connections are truly floating when power is off.  
These features make the TJA1145 the ideal choice for high-speed CAN networks  
containing nodes that are always connected to the battery supply line but, in order to  
minimize current consumption, are only active when required by the application.  
2. Features and benefits  
2.1 General  
Fully compliant with the ISO 11898-2, ISO 11898-5 and ISO 11898-6 standards  
Autonomous bus biasing according to ISO 11898-6  
Optimized for in-vehicle high-speed CAN communication  
No ‘false’ wake-ups due to CAN FD frame detection in TJA1145/FD variants  
2.2 Designed for automotive applications  
8 kV ElectroStatic Discharge (ESD) protection, according to the Human Body Model  
(HBM) on the CAN bus pins
