TJA1442AT/0Z

TJA1442AT/0Z is a high-speed CAN transceiver with Standby mode. It is a member of the TJR144x family of transceivers that provide an interface between a CAN or CAN FD protocol controller and the physical two-wire CAN bus. TJR144x transceivers implement the CAN physical layer as defined in ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5, and are fully interoperable with high-speed Classical CAN and CAN FD transceivers. All TJR144x variants enable reliable communication in the CAN FD fast phase at data rates up to 5 Mbit/s and are qualified to AEC-Q100 Grade 0, supporting operation at 150°C ambient temperature. The TJR1442 is intended as a simple replacement for high-speed Classical CAN and CAN FD transceivers. It offers pin compatibility and is designed to avoid changes to hardware and software design, allowing the TJR1442 to be easily retrofitted to existing applications. An AEC-Q100 Grade 1 variant, the TJA1442, is available to support operation up to 125°C ambient temperature.

• Standard CAN and CAN FD data bit rates up to 5 Mbit/s
• Low Electromagnetic Emission (EME) and high Electromagnetic Immunity (EMI)
• Undervoltage detection with defined handling on all supply pins
• Functionality guaranteed from undervoltage detection thresholds up to max limiting voltage values
• Defined behaviour below the undervoltage detection thresholds
• Transceiver disengages from the bus when the supply voltage drops below the Off mode threshold
• Internal biasing of TXD and mode selection input pins, to enable defined fail-safe behaviour
• Very low-current standby mode with host and bus wake-up capability
• CAN wake-up receiver powered by VIO allowing VCC to be shut down
• CAN wake-up pattern filter time of 0.5μs to 1.8μs, meeting CAN and CAN FD requirements
