Patent number: 7126296Abstract: A directional load is capable of operating in multiple directions. For example, a directional motor may rotate in clockwise and counterclockwise directions. A directional load driver generates output signals causing the directional load to operate in one of the directions, thereby providing a requested function. The requested function is identified using an input signal, such as a state-encoded input signal. The state-encoded input signal could be received by the directional load driver over a single wire or through a single input pin. Under the control of the directional load driver, the directional load could perform any of a wide variety of functions. In automotive applications, the directional load could open or close a window, lock or unlock a door, or open or close a door. In other applications, the directional load could be used with a residential door lock, a home automation system, or an industrial control.Type: GrantFiled: June 30, 2005Date of Patent: October 24, 2006Assignee: STMicroelectronics, Inc.Inventors: Gary J.
