1. General description
2. Features and benefits
2.1 General
2.2 Low-power management
2.3 Protection
The TJA1048 is a dual 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 (up to 1 Mbit/s) CAN applications in the
automotive industry, providing the differential transmit and receive capability to (a
microcontroller with) a CAN protocol controller.
The TJA1048 is a step up from the TJA1040, PCA82C250 and PCA82C251 high-speed
CAN transceivers. It offers improved Electro Magnetic Compatibility (EMC) and
ElectroStatic Discharge (ESD) performance, and also features:
These features make the TJA1048 an excellent choice for all types of HS-CAN networks
containing more than one HS-CAN interface that require a low-power mode with wake-up
capability via the CAN bus, especially for Body Control and Gateway units.
