NXP Semiconductors TJA1051 High-Speed CAN Transceivers

　　NXP Semiconductors TJA1051 High-Speed CAN Transceivers offer an interface between a Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus. The TJA1051 is intended for high-speed CAN applications in the automotive industry. The device provides differential transmit and receive capability to (a microcontroller with) a CAN protocol controller.The TJA1051 Transceivers are part of the third generation of high-speed CAN transceivers from NXP Semiconductors, supplying significant improvements over first- and second-generation devices such as the TJA1050. The TJA1051 also provides improved ElectroMagnetic Compatibility (EMC) and ElectroStatic Discharge (ESD) performance with:

　　• Ideal passive behavior to the CAN bus when the supply voltage is off

　　• TJA1051T/3 and TJA1051TK/3 can be interfaced directly to microcontrollers with supply voltages from 3V to 5V

　　The TJA1051 implements the CAN physical layer defined in ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5. This implementation allows reliable communication in the CAN FD fast phase at data rates up to 5Mbit/s. These features make the TJA1051 an exceptional choice for all types of HS-CAN networks in nodes that do not require a standby mode with wake-up capability through the bus.

　　The TJA1051 is a high-speed CAN stand-alone transceiver with Silent mode and available in three versions, determined only by the function of pin 5:

　　• The TJA1051T is backward compatible with the TJA1050

　　• The TJA1051T/3 and TJA1051TK/3 allow for direct interfacing to microcontrollers with supply voltages down to 3V

　　• The TJA1051T/E allows the transceiver to be switched to a very low-current Off modeFEATURES
