Door Module Drivers

Image

ST’s actuator drivers are designed for state-of-the-art automotive door-module applications. Our devices employ a scalable actuator-driving concept, which includes package and software compatibility with the wide variety of door electronics used by the industry.

The actuator drivers support all regular door-module loads such as window lifting, lock motors, mirror leveling, mirror retraction, defrosters, and several lighting functions from incandescent bulbs to LEDs. For high-end cars, a new electrochromic mirror glass control IP is available.

Key features include:

  • Scalable solutions that address door electronics schemas across the industry
  • Power-management functionality (with Partial Networking IP on selected products
  • Integrated CAN or LIN transceiver
  • Control and diagnostics via SPI bus
  • Small power packages with superior thermal performances
