PURPOSE:To provide a power window control circuit which controls the opening and closing of automobile power windows, can reduce current supply even if a plurality of windows are operated simultaneously, and can therefore reduce the loads on a power source portion and wiring. CONSTITUTION:This power window control circuit includes a rectangular wave generator circuit A for supplying driving currents to a driver's seat motor M1 for operating the driver's-seat side window and a passenger seat motor M2 for operating the passenger-seat side window and a rectangular wave generator circuit B for supplying driving currents to a right backseat motor M3 for operating the right-backseat side window and a left backseat motor M4 for operating the left-backseat side window. The driving currents outputted by the rectangular wave generator circuit A are inverted with respect to those outputted by the rectangular wave generator circuit B, so that even when the four windows are operated simultaneously, the current supply from a power source can be suppressed. |
