Product Introduction

Overview

The TJA1020T/VM,112 is a LIN (Local Interconnect Network) transceiver produced by NXP USA Inc. This component serves as the interface between the LIN master/slave protocol controller and the physical bus in automotive sub-networks. It is designed to support baud rates up to 20 Kbaud and is optimized for low electromagnetic emission (EME) and high electromagnetic immunity (EMI).

Key Features

  • Baud rate up to 20 Kbaud
  • Very low ElectroMagnetic Emission (EME)
  • High ElectroMagnetic Immunity (EMI)
  • Low slope mode for further reduction of EME
  • Passive behavior in unpowered state
  • Input levels compatible with 3.3 and 5 V devices
  • Integrated termination resistor for Network (LIN) slave applications
  • Wake-up source recognition (local or remote)
  • Supports K-line like functions
  • Very low current consumption in sleep mode with local and remote wake-up
  • Transmit data (TXD) dominant time-out function
  • Bus terminal and battery pin protected against transients
  • Bus terminal short-circuit proof to battery and ground
  • Thermally protected

Applications

The TJA1020T/VM,112 is primarily intended for in-vehicle sub-networks using baud rates from 2.4 to 20 Kbaud. It is suitable for various automotive applications where reliable and low-emission communication over the LIN bus is required. This includes body control modules, door control units, and other automotive subsystems that need to communicate via the LIN protocol.
