Sunroof Controller

Overview

Description

A sunroof control system combines an MCU and intelligent power device (IPD) to deliver precise, efficient, and reliable operation. The MCU serves as the system's core, interpreting user inputs such as switches or touch commands and managing functions like tilt, slide, and full open/close positions. This system integrates seamlessly with the vehicle's body control network using CAN or LIN communication protocols. It is designed to prioritize safety, optimize energy usage, and ensure a compact, durable architecture for modern automotive applications.

System Benefits:

  • The MCU features low current consumption, ideal for automotive applications.
  • The IPD drives the sunroof motor with high efficiency, combining power handling with integrated protection features.
  • Benefits include enhanced safety, energy efficiency, compact design, and durability.
  • The combination of the MCU and IPD ensures precise motor control, robust protection, and an improved user experience, meeting modern automotive standards for comfort and reliability.
