About

Multi-faceted automotive BCMs for functional vehicle control

BCMs actuate, monitor, and control the vehicle's body functions and related electronic control units (ECU). Acting as the brain of the vehicle's body, body control modules manage car functions like lighting, windows, door locks, seat controls, and more. Infineon's advanced BCM solutions offer robust performance, reliability, and scalability, empowering car manufacturers to enhance vehicle functionality and provide a seamless and intuitive driving experience. With Infineon's body control module designs, vehicles are equipped with intelligent control systems that optimize comfort, convenience, and safety.

Smart BCM: Safer, smoother driving with greater function and comfort

The body control module combines all six core functionalities of an electronic control unit:

  • Supply of the module with Infineon Supply ICs from various product families: OPTIREG™ Linear, OPTIREG™ Switcher, and OPTIREG™ SBC (system basic chip with integrated low-drop voltage regulator or DC-DC).
  • Actuation of the vehicle function loads with power ICs from various product families: PROFET™+2, PROFET™ Load Guard, Power PROFET™, SPOC™+2, SPIDER+, HITFET™+, LITIX™, MOTIX™ multi MOSFET driver, and MOSFETs.
  • Sensing with magnetic sensors from the XENSIV™ family (and monitoring in the BCM) or integrated into the power ICs. For car access, Infineon offers transceivers and receivers in Remote Keyless Entry (RKE) and Passive Keyless Entry (PKE).
  • Control of the whole vehicle body with Traveo™ T2G and AURIX™ microcontrollers.
  • Communication with other car functions via the vehicle bus system by LIN or CAN/CAN FD transceiver families or integrated with supply into the system basic chip family.
  • High-performance flash memory solutions from the Semper™ NOR Flash families.
Customized driving experience with versatile body control module units

In the ever-evolving automotive landscape, customization has become a key driver of customer satisfaction. To meet this demand, Infineon provides a range of versatile control module units that allow automakers to create personalized driving experiences.
