Product Description

Overview of TJA1048TK

The TJA1048TK is a high-performance CAN (Controller Area Network) transceiver manufactured by Semiconductors. It belongs to the third generation of high-speed CAN transceivers and offers significant improvements over its first- and second-generation predecessors, such as the TJA1040.

Key Features

1. Dual High-Speed CAN Transceiver:
   • Provides an interface between a Controller Area Network (CAN) protocol controller and the physical two-wire CAN bus.
   • Designed for high-speed CAN applications in the automotive industry.
2. Improved EMC and ESD Performance:
   • Offers enhanced Electromagnetic Compatibility (EMC) and ElectroStatic Discharge (ESD) protection.
3. Standby Mode with Bus Wake-Up Capability:
   • Features a very low-current standby mode on both channels, with the ability to wake up the bus.
4. Direct Interfacing with Microcontrollers:
   • Can be interfaced directly to microcontrollers with supply voltages ranging from 3 V to 5 V.
5. Compliance with ISO Standards:
   • Implements the CAN physical layer as defined in the ISO11898 standard (ISO11898-2:2003, ISO11898-5:2007) and is compliant with the updated version ISO 11898-2:2016, including CAN FD and SAE J2284-4/5.
6. High-Speed Data Rates:
   • Supports data rates up to 5 Mbps in the CAN FD fast phase, enabling reliable communication at high speeds.
7. Package and Dimensions:
   • Typically packaged in an HVSON14 or similar package.
   • Dimensions may vary slightly depending on the manufacturer and production batch.

Applications

The TJA1048TK is ideal for various HS-CAN networks that require multiple HS-CAN interfaces and a low-power mode with wake-up capability via the CAN bus. It is particularly suited for applications such as body control and gateway units in the automotive industry.

Additional Benefits

1. Predictable Functional Behavior:
   • The transceiver disconnects from the bus (zero-load state) when not powered on.
2. Protection Mechanisms:
   • High ESD handling capability on bus pins.
   • Provides transient protection for bus pins in automotive environments.
   • Includes transmit data (TXD) dominant timeout functionality.
   • Features undervoltage detection on VCC and VIO pins.
   • Incorporates thermal protection to safeguard the component.
