Philips Semiconductors Product specification
Light position controller 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.
