The present invention provides a time light splitting system driving device which comprises a driving circuit and a motor. The driving circuit drives the motor to generate torque. The motor drives a lens frame to move. The driving circuit comprises a micro-torque control circuit which controls the lens to generate micro-torque when the lens frame is in a position limiting part. The lens frame arrives at a required position slowly and smoothly under the function of micro-torque for preventing shake. The safety, reliability and working efficiency of the whole time light splitting system drivingdevice are increased.
