LIN slave for IO extension and interior lighting applications

MLX81109

The MLX81109 LIN slave provides a single chip solution for different IO extension applications.

All necessary components like physical layer LIN transceiver, LIN controller, voltage regulator, and 16-bit RISC-based microcontroller, as well as supporting functions like ADC, 16-bit PWM, constant current high voltage capable IOs are integrated into the chip.

It also includes the possibility for LIN auto-configuration and can thus be used for other applications requiring a low pin count fully integrated LIN slave. The LIN protocol handler meets all LIN standards including LIN2.x, as well as SAE J2602.

To support a high thermal performance by keeping the low cost target, our MLX81109 is offered in a QFN 5x5 package.
