Dome Module

Tools and Software
HW Evaluation Tools
Key Products
Dome modules, generally placed at the top of the car roof, control dome and map lights as well as convenience lighting designed to illuminate driver and passenger compartments including the trunk and storage areas. They can also be used to control windows and sunroofs as well as emergency call buttons.

Greater efficiency and reliability

In designing a dome module, key challenges are high-efficiency and reliability together with extensive diagnostics for the variety of loads – LED, bulbs and motors – controlled as well as reduced real estate and weight. 

Our extensive offer of high/low-side and H-bridge integrated drivers with low losses and extensive diagnostics are a dependable solution made available to designers of dome modules for modern vehicles.
