LOW POWER ANALOG SOLUTIONS FOR AUTOMOTIVE APPLICATIONS
Solutions for Connectivity Applications
Connectivity within the vehicle is dominated today by two
main network protocols: CAN (Controller Area Network) and
LIN (Local Interconnect Network). CAN utilizes a robust,
high-speed protocol, usually linking major nodes or

subsystems within the vehicle, such as ABS, airbag,
powertrain and suspension control modules. LIN is a low-
speed, single-wire network that usually links nodes within
a vehicle subsystem, such as body electronics, headlight
controls and occupant detection.
