The kernel of a stepping motor driver circuit is the ring pulse distributor. A design scheme of two-phase step motor's driving circuit is presented in this paper. The circuit includes the ring pulse distributor based on E^2PROM and reversible counter and a periphery driving chip L9110. The circuit is simple and reliable, it can be directly connected with MCU and the interface with MCU is very simple, and it can drive and control the two-phrase stepping motor well.
