L297 Stepper Motor Controller (IC) 12706 Connection : 3 pinIntroduction : The L297 Stepper Motor Controller IC generates four phase drive signals for two phase bipolar and four phase unipolar step motors in microcomputer controlled applications. The motor can be driven in half step, normal and wave drive modes and on chip PWM chopper circuits permit switch mode control of the current in the windings. Features : Supply voltage : 10V. Input signals : 7V. Half Full step mode. Normal Wave drive. Switchmode load
