Automotive Central Body Controller
Load Drivers:
Main load driver types in a central body controller are lights and relay
drivers.
The switches and drivers for the exterior lighting are placed on the
controller directly.
Relays are used to power other electronic modules or loads.
Current monitoring supervises demand from the distributed loads, other
ECUs and used for charge & load management of the car battery.
RFID Functions - Most common automotive RFID functions are:
Immobilizer and the remote keyless entry system.
LF base station IC for encrypted communication with the ignition key
(immobilizer)
