Zonal & body domain controller

Driving vehicle comfort, convenience, lighting and in-vehicle communication

Zonal and body domain controllers drive various comfort, convenience and lighting loads that create a relaxing and enjoyable driving experience. As domain-based vehicle architectures shift toward zone-based architectures, body domain controllers are evolving into zone controllers incorporating additional capabilities such as localized power distribution and higher bandwidth in-vehicle network communication capabilities. We offer a wide range of motor drivers, smart power switches and LED drivers featuring robust protection and diagnostic capabilities for safely driving a multitude of loads. In addition, we have a broad portfolio of power management, ideal diode controllers and CAN, CAN-FD, LIN and Ethernet interfaces to optimize your system power and communication interfaces. Explore our technical content and additional resources to jump-start your zone or body domain controller development.

Reduce cable length and weight

Smart high-side switches replace melting fuses in vehicles providing resettable outputs, configurable I2T settings and improved consistency across temperature. These features allow vehicle architects to implement configurable protection in localized zone controllers, reduce the length of wiring required from traditional fuse box implementations and reduce the wire gauge. Our smart high-side switches with accurate current sense and intelligent diagnostics allow you to implement accurate and reliable fuse replacement switches.
