VEHICLE POWER WINDOW CONTROL

摘要

VEHICLE POWER WINDOW CONTROL A control for a vehicle window driving motor in an H-switch semiconductor bridge with an SCR and a FET in each opposite armature current path includes control logic circuitry enabling one-touch actuation of window movement in either direction with stoppage by actuating either actuation device and with flip-flop control of the bridge elements to prevent shorting out the power supply. A variation provides automatic stoppage in the up direction by stall current sensing with automatic reverse after a time delay to allow the SCR conducting during upward movement to turn off.
