TJA1057GTK/3Z

TJA1057GTK/3Z is a high-speed CAN transceiver. It 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 the differential transmit and receive capability to (a microcontroller with) a CAN protocol controller. It offers a feature set optimized for 12V automotive applications, with significant improvements over first- and second-generation CAN transceivers from NXP, such as the excellent Electromagnetic Compatibility (EMC) performance. It also displays ideal passive behaviour to the CAN bus when the supply voltage is off. Variants with a VIO pin can be interfaced directly with microcontrollers with supply voltages from 3.3V to 5V. It implements the CAN physical layer as defined in ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5. Additional timing parameters defining loop delay symmetry are specified for the other variants.

• Fully ISO 11898-2:2016, SAE J2284-1 to SAE J2284-5 and SAE J1939-14 compliant
• Optimized for use in 12V automotive systems
• Functional behaviour predictable under all supply conditions
• Transceiver disengages from bus (high-ohmic) when supply voltage drops below undervoltage threshold
• Transmit Data (TXD) dominant time-out function, internal biasing of TXD and S input pins
• High ESD handling capability on the bus pins (8kV IEC and HBM)
• Bus pins protected against transients in automotive environments
• Supply voltage range from 4.5 to 5.5V (Taj = -40°C to +150°C)
• Supply current range from 0.1 to 1.2mA (Silent mode, VTXD = VIO, Taj = -40 to +150°C)
• HVSON8 package, virtual junction temperature range from -40 to +150°C
