TJA1145ATK/0Z Electronic Components

Product Introduction

The TJA1145ATK/0Z Electronic Components 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 TJA1145A features very low power consumption in Standby and Sleep modes and supports ISO 11898-2:2016 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 FD variants TJA1145AT/FD and TJA1145ATK/FD (see Section 7.3.2 for further details on CAN FD).Advanced power management regulates the supply throughout the node and supports local and remote wake-up functionality.

The TJA1145A implements the CAN physical layer as defined in ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5.These features make the TJA1145A 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.
