TJA1048 Dual high-speed CAN transceiver with Standby mode Rev. 6 19 March 2018 Product data sheet 1. General description 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: Ideal passive behavior to the CAN bus when the supply voltage is off A very low-current Standby mode with bus wake-up capability on both channels Can be interfaced directly to microcontrollers with supply voltages from 3 V to 5 V The TJA1048 implements the CAN physical layer as defined in ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5. 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. Features and benefits 2.1 General Two TJA1042/3 HS-CAN transceivers combined monolithically in a single package ISO 11898-2:2016 and SAE J2284-1 to SAE J2284-5 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) V input allows for direct interfacing with 3 V to 5 V microcontrollers IO 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 qualifiedTJA1048 NXP Semiconductors Dual high-speed CAN transceiver with Standby mode 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 V allows shut down of V IO CC 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 V and V CC IO Thermally protected 3.
