MLX80104 LIN Switch/LIN IO-Control

By Melexis Technologies NV 73

MLX80104 LIN Switch/LIN IO-Control

Melexis' MLX80104 is a fully-integrated LIN slave for switch or similar IO-Control/Extension in automotive applications. 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 MLX80104 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, powerful, cheap switch slave nodes for LIN bus systems in a short timeframe.
