Abstract: In order to meet the application requirements of the stepping motor in the specifie field,a full bridge driving circuit was designed by using the discrete circuit.With IRF520 as the power amplifier and IR2103 as the gate drive chip,through the sampling resistor and the high pricision operational amplifier to obtain the phase current of the stepping motor, so as to realize the current micro step control of stepping motor.Presented the full bridge driving circuit,realized the precision control of the stepping motor. Key words: IR2103,micro step control,full bridge drive
