Overview

The BD41030HFN-CGTR is a single LIN bus transceiver designed for automotive and industrial applications. It facilitates communication between a microcontroller and the LIN physical layer, supporting data rates up to 20kbps. This device is AEC-Q100 qualified and offers robust protection features for reliable operation in harsh environments.

Why Choose This Part

This transceiver offers high reliability with AEC-Q100 qualification and a wide operating temperature range of -40degC to 125degC. Its low quiescent current in sleep mode (8uA) makes it suitable for power-sensitive applications. Integrated protection features like short-circuit resistance and thermal shutdown enhance system robustness and fault tolerance.

Applications

Automotive Body Control Modules (BCM)
Used in automotive BCMs for controlling various comfort and convenience functions like power windows, door locks, and climate control, leveraging the LIN bus for cost-effective networking.
Automotive Sensor Interfacing
Enables microcontrollers to interface with peripheral sensors (e.g., rain sensors, light sensors) over the LIN bus, simplifying wiring harnesses and reducing system cost.
Industrial LIN Bus Systems
Applicable in industrial control systems where a low-cost, robust, single-wire serial communication is required for non-critical applications.
Infotainment System Peripherals
Integrates peripherals within automotive infotainment systems, such as control panels or small display modules, using the LIN bus for communication.
Actuator Control in Vehicles
Provides the physical layer interface for controlling various actuators (e.g., small motors, solenoids) in automotive systems that communicate via LIN.
