TJA1448BT/0Z

TJA1448BT/0Z is a dual high-speed CAN transceiver with standby mode. It provides an interface between a Controller Area Network (CAN) or CAN FD (Flexible Data rate) protocol controller and the physical two-wire CAN bus. This transceiver implements the CAN physical layer as defined in ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5, and is fully interoperable with high-speed Classical CAN and CAN FD transceivers. These variants enable reliable communication in the CAN FD fast phase at data rates up to 5Mbit/s. It is intended as a simple replacement for dual high-speed classical CAN and CAN FD transceivers, such as the TJA1059 from NXP. It offers pin compatibility and is designed to avoid changes to hardware and software design, allowing the TJA1448 to be easily retrofitted to existing applications.

• ISO 11898-2:2016, SAE J2284-1 to SAE J2284-5 and SAE J1939-14 compliant
• Low Electromagnetic Emission (EME) and high Electromagnetic Immunity (EMI)
• Qualified according to AEC-Q100 Grade 1
• Fully independent control of two transceivers combined monolithically in a single package
• Undervoltage detection with defined handling on all supply pins
• Full functionality guaranty from undervoltage detection thresholds up to max limiting voltage values
• Defined behaviour below the undervoltage detection thresholds
• Transceiver disengages from bus (high-ohmic) when supply voltage drops below off mode threshold
• Internal biasing of TXD and mode selection input pins, to enable defined fail-safe behaviour
• SO14 package, virtual junction temperature range from -40 to +150°C
