Abstract

The invention relates to the field of automation, and especially relates to a motor control integrated circuit, and the circuit is used for a fountain control system. The circuit comprises a control circuit; an integrated step control drive circuit, wherein a control receiving end and a control output end are connected so as to receive a control signal, and the integrated step control drive circuit outputs a step drive signal through a drive output end according to the control signal; a half-bridge drive circuit, wherein the half-bridge drive circuit outputs a first pre-drive signal according to the step drive signal through a first pre-drive output end, and outputs a second pre-drive signal through a second pre-drive output end; a push-pull circuit which comprises two switching modules and one motor drive end, wherein the two switching modules are driven by the first and second pre-drive signals to switch alternately, so as to generate a motor drive signal at the motor drive end to drive one stepping motor. The circuit provided by the invention can meet the requirements of high voltage of a large-scale underwater industrial control project, is higher in integration degree, and can save the space.
