TJA1048: Dual high-speed CAN transceiver with Standby mode

The TJA1048 is a dual 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 CAN applications in the automotive industry, providing the differential transmit and receive capability to (a microcontroller with) a CAN protocol controller.

The TJA1048 belongs to the third generation of high-speed CAN transceivers from NXP Semiconductors, offering significant improvements over first- and second-generation devices such as the TJA1040. It offers improved Electro Magnetic Compatibility (EMC) and ElectroStatic Discharge (ESD) performance, and also features:

The TJA1048 implements the CAN physical layer as defined in the current ISO11898 standard (ISO11898-2:2003, ISO11898-5:2007) and the pending updated version of ISO 11898-2:2016. Pending the release of the updated version of ISO11898-2:2016 including CAN FD and SAE J2284-4/5, additional timing parameters defining loop delay symmetry are specified. This implementation enables reliable communication in the CAN FD fast phase at data rates up to 5 Mbit/s.

These features make the TJA1048 an excellent choice for all types of HS-CAN networks containing more than one HS-CAN interface that require a low-power mode with wake-up capability via the CAN bus, especially for Body Control and Gateway units.

2.1 General

• Two TJA1042/3 HS-CAN transceivers combined monolithically in a single package
• Fully ISO 11898-2:2003 and ISO 11898-5:2007 compliant
• Timing guaranteed for data rates up to 5 Mbit/s in the CAN FD fast phase
• Suitable for 12 V and 24 V systems
• Low ElectroMagnetic Emission (EME) and high ElectroMagnetic Immunity (EMI)
• VIO input allows for direct interfacing with 3 V to 5 V microcontrollers
• Available in SO14 and HVSON14 packages
• Leadless HVSON14 package (3.0 mm × 4.5 mm) with improved Automated Optical Inspection (AOI) capability
• Dark green product (halogen free and Restriction of Hazardous Substances (RoHS) compliant)
• AEC-Q100 qualified

2.2 Low-power management

• Very low-current Standby mode with host and bus wake-up capability
• Functional behavior predictable under all supply conditions
• Transceiver disengages from the bus when not powered up (zero load)
• Wake-up receiver powered by VIO; allows shut down of VCC

2.3 Protection

• High 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
