The MLX80105 is a fully integrated LIN slave for switch or similar IO-control/extension applications in automotive.

It is suitable for bus systems according to LIN 2.x as well as SAE J2602. All necessary components are integrated into one single silicon die. The MLX80105 consists of a microcontroller, voltage regulator, LIN physical layer, LIN protocol driver, ADC, PWM as well as high voltage IOs.

The combination of a physical layer LIN transceiver and a LIN protocol controller along with easy to configure switch inputs and PWM outputs makes it possible to develop simple, but powerful and cheap switch slave nodes for LIN Bus systems in a short timeframe.

Doors modules, steering wheel, etc.
