1. General description
2. Features
2.1 General
2.2 Low-power management
2.3 Protection
The TJA1051 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 (up to 1 Mbit/s) CAN applications in the
automotive industry, providing differential transmit and receive capability to (a
microcontroller with) a CAN protocol controller.
The TJA1051 is a up from the TJA1050 high-speed CAN transceiver. It offers improved
ElectroMagnetic Compatibility (EMC) and ElectroStatic Discharge (ESD) performance,
and also features:
These features make the TJA1051 an excellent choice for all types of HS-CAN networks,
in nodes that do not require a standby mode with wake-up capability via the bus.
