Overview
The TDA3629T/N2,112 is a monolithic integrated circuit designed by NXP USA Inc. as a light position controller. This device is primarily intended for use in automotive headlight systems to control the elevation of the light beam. The controller operates by adjusting the light beam's elevation based on inputs from a setting potentiometer on the dashboard and a feedback potentiometer mechanically coupled to the control motor. This ensures precise and user-controlled adjustment of the headlight beam.
