Lighting Body Control Module is the generic module that can be used by all type of cars and commercial vehicles. It consists of 10 channel high side drivers
which can be used to control various types of loads like headlamp, horn, stop lamps, turn indicators, etc depending on customers requirement. All the 10 channels have short circuit protection, over temperature protection and auto restart protection. It provides the battery voltage sensing, ignition/RPM ON/OFF sensing provision which can be used to customize the application as per customers’ requirement. 5 channels of this module are configured as BCM while the remaining 5 are configured as Lighting Module. For BCM channels, loads will turn ON only if ignition is turned ON with respective input signal provided. Flasher functionality with low load detection can be easily implemented as it has current sensing feature.

For the channels of Lighting Module, output turns on directly if ignition key is turned ON. Lighting control module can also be used as a replacement for fuse box as it has current sensing, short circuit protection as well as auto restart feature. As this board has the input for RPM sensing, Anti cranking feature can be implemented with minor changes in the firmware in accordance to customers’ requirement.
