Body Control Module (BCM) / LED Head Light Unit
A body control module (BCM) integrates several functions, including various lights and door locks. It has a gateway function for communication with a CAN or LIN. Such a unit requires components with CAN/CAN FD/LIN network support, a selection of package sizes and memory capacities to match a variety of system scales, low EMI to prevent radio noise interference with vehicle wiring systems, and low current consumption to reduce battery drain when in standby status.
Renesas offers kit solutions comprising MCUs, analog devices, and power devices for optimized body control. Also, we supply power devices and LED headlight controllers with overcurrent detection and diagnostic functions, enabling low current consumption in LED headlight units, which have become increasingly popular in recent years.
