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.

FEATUREs
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)

Low-power management
■ Functional behavior predictable under all supply conditions
■ Transceiver disengages from the bus when not powered up (zero load)

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 VCC and VIO
■ Thermally protected
