TJA1057GTJ-TD

TAJ1057 belongs to the Mantis series of high-speed CAN transceivers. It provides an interface between the controller area network 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 capabilities for CAN protocol controllers. TAJ1057 offers a feature set optimized for 12 V automotive applications with significant improvements. When the supply voltage is switched off, TAJ1057 also exhibits ideal passive behavior on the CAN bus. Versions with a VIO pin can interface directly with microcontrollers operating at supply voltages from 3.3 V to 5 V. TAJ1057 implements the CAN physical layer as defined in ISO 11898-2:2024 Edition 3 and SAE J2284-1 through SAE J2284-5. The TAJ1057T specification supports data rates up to 1 Mbit/s. Additional timing parameters defining loop delay symmetry are specified for other variants. This implementation supports reliable communication at data rates up to 5 Mbit/s in the CAN FD fast phase. These features make TAJ1057 an excellent choice for high-speed CAN networks requiring only basic CAN functionality.

Key features

• Fully compliant with ISO 11898-2:2024, SAE J2284-1 to SAE J2284-5, and SAE J1939-14
• Optimized for 12 V automotive system applications
• Low EMI and high electromagnetic immunity per EMC standards IEC TS62228 and SAE J2962-2:2019
• Deep green product (halogen-free and RoHS compliant)
• Models with VIO pin allow direct interface with 3.3 V to 5 V microcontrollers. Models without VIO pin are compatible with 3.3 V and 5 V microcontrollers, provided the microcontroller I/O is 5 V tolerant
• Predictable functional behavior under all supply conditions
• Transceiver disconnected from bus (high impedance) when supply voltage falls below undervoltage threshold
• TXD dominant timeout function
• Internally biased TXD and S input pins
• High ESD handling capability on bus pins (8 kV IEC and HBM)
• Bus pins protected against transients in automotive environments
• Undervoltage detection on VCC and VIO pins
• Thermal protection
