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 (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 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 3 V to 5 V 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 ? Fully ISO 11898-2 compliant ? Suitable for 12 V and 24 V systems ? Low ElectroMagnetic Emission (EME) and high ElectroMagnetic Immunity (EMI) ? VIO input on TJA1051T/3 and TJA1051TK/3 allows for direct interfacing with 3 V to 5 V 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 and HVSON8 packages ? 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) 2.2 Low-power management ? Functional behavior predictable under all supply conditions ? Transceiver disengages from the bus when not powered up (zero load)
