Overview

The BD41030FJ-CGE2 is an AEC-Q100 qualified LIN (Local Interconnect Network) physical layer transceiver designed for automotive data communication at rates up to 20kbps. It serves as the interface between a protocol controller and the physical bus, featuring a wide operating voltage range of 5V to 27V and integrated protection against short circuits.

Why Choose This Part

This transceiver offers extremely low electromagnetic emission (EME) and high immunity (EMI), reducing the need for external filtering components. It features a low-power sleep mode consuming only 3uA and includes a built-in terminator for LIN slave applications, simplifying PCB design.

Applications

Automotive Body Control
Ideal for low-speed networking in door modules, seat adjusters, and mirror controls where cost-effective communication is required.
Climate Control Systems
Used to connect HVAC sensors and actuators to the central ECU within the cabin network.
Industrial Sensor Clusters
Suitable for robust, low-speed industrial master-slave configurations that require high electromagnetic immunity.

Getting Started

To evaluate this part, connect the TXD and RXD pins to a microcontroller's UART interface (compatible with 3.3V or 5.0V logic) and provide a 12V nominal supply to the BAT pin. Ensure a 100nF decoupling capacitor is placed near the BAT pin and follow standard LIN bus physical layer layout practices to maintain signal integrity.
