Product specification

TDA3629

FEATURES

• Low positional error

• Low noise sensitivity due to hysteresis

• Low supply current

• Thermally protected

• Broken wire and short-circuit indication on SET input

• Brake function by short-circuiting the motor

• Hysteresis level set externally.

GENERAL DESCRIPTION

The Light position controller (Leucht Weiten Steller, LWS)

is a monolithic integrated circuit intended to be used in

passenger cars. This device adapts the elevation of the

light beam of the head light of the car to a state defined by

the car driver using a potentiometer on the dashboard.
