TJA1051 High-speed CAN transceiver Rev. 9 28 November 2017 Product data sheet 1. General description 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 CAN applications in the automotive industry, providing differential transmit and receive capability to (a microcontroller with) a CAN protocol controller. The TJA1051 belongs to the third generation of high-speed CAN transceivers from NXP Semiconductors, offering significant improvements over first- and second-generation devices such as the TJA1050. It offers improved ElectroMagnetic Compatibility (EMC) and ElectroStatic Discharge (ESD) performance, and also features: 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 3Vto5V The TJA1051 implements the CAN physical layer as defined in ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5. This implementation enables reliable communication in the CAN FD fast phase at data rates up to 5 Mbit/s. 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. 2. Features and benefits 2.1 General ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 compliant Timing guaranteed for data rates up to 5 Mbit/s in the CAN FD fast phase Suitable for 12 V and 24 V systems Low ElectroMagnetic Emission (EME) and high ElectroMagnetic Immunity (EMI) V input on TJA1051T/3 and TJA1051TK/3 allows for direct interfacing with 3 V to 5 V IO microcontrollers (available in SO8 and very small HVSON8 packages respectively) EN input on TJA1051T/E allows the microcontroller to switch the transceiver to a very low-current Off mode Available in SO8 package or leadless HVSON8 package (3.0 mm 3.0 mm) with improved Automated Optical Inspection (AOI) capability Dark green product (halogen free and Restriction of Hazardous Substances (RoHS) compliant) AEC-Q100 qualifiedTJA1051 NXP Semiconductors High-speed CAN transceiver 2.2 Low-power management Functional behavior predictable under all supply conditions Transceiver disengages from the bus when not powered up (zero load) 2.3 Protection High ElectroStatic Discharge (ESD) handling capability on the bus pins Bus pins protected against transients in automotive environments Transmit Data (TXD) dominant time-out function Undervoltage detection on pins V and V CC IO Thermally protected 3.
