Explore the block diagram for onsemi’s Body Control Module (BCM). The BCM acts as a central vehicle gateway for signal outputs to execute functions for comfort and convenience applications such as lighting, windshield wiper control, door locks, mirrors, windows, powertrain components and wireless interfaces.
The onsemi BCM functions as a communication gateway by routing vehicle messages between various ECU based subsystems in the vehicle. Depending on the complexity required, there may be multiple BCM systems integrated into a vehicle.
The primary system blocks in the topology include:
- • Power management including reverse battery protection
- • System basis chip and transceivers for in-vehicle communications
- • Signal conditioning of any digital and analog inputs
- • High and low side drivers
- • LED drivers
- • Motor drive and control
