Control Module for Automotive Light Applications

With the use of the Kinetis EA MCU for automotive, the design provides a cost-effective solution for automotive applications. Integration with the MC10XS3412JHFK high side switch also enables the circuit to control automotive lighting and diagnose the status of the headlamps. The control of these lights includes high and low beam, turning and braking. The MC33662 and the MC33901, which are the LIN and CAN transceivers respectively, are used together with the potentiometer to control the light level and status of the bulbs.

This design is not limited to automotive applications. It is also applicable to traffic lights, stage lights, and some commercial applications.
