Abstract: The present invention discloses a low-power control circuit that comprises a receiver circuit and a control chip, wherein the receiver circuit is signally connected with the control chip, and the control chip is connected with an actuating mechanism. The present invention is characterized in that the low-power control circuit also comprises a clock generator control circuit which is respectively and signally connected with the receiver circuit and the control chip. Because the clock generator control circuit is adopted in the present invention to close the receiver circuit at regular time, the control chip is awakened only when output signal exists in the receiver circuit. Therefore, the control chip is in sleep state (also called standby state) in general.

Abstract: A window covering driving device includes a motor and a control circuit, the control circuit is provided with a microprocessor, a control wire, a control signal input terminal, and a switching circuit and the motor is connected to a drive power supply via the switching circuit. The switching circuit is connected to the microprocessor and the control signal input terminal is connected to the microprocessor via the control wire. A safety position limiting wire is also included with one end of the safety position limiting wire being connected to the microprocessor and the other end is connected to a safety position limiting signal control terminal. The safety position limiting wire and safety position limiting signal control terminal are attached so that, when the safety position limiting signal control terminal is at the position limiting state, as the motor runs to the position limiting position, it will automatically stop.
