Overview
The TDA3629T/YM,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 applications, specifically to control the elevation of the light beam in a vehicle's headlight. The controller operates by adjusting the light beam's elevation based on input from a setting potentiometer on the dashboard and feedback from a feedback potentiometer mechanically coupled to the control motor.
