L6219

L6219 Stepper motor driver Features ■ Able to drive both windings of bipolar stepper motor ■ Output current up to 750 mA each winding ■ Wide voltage range: 10 V to 46 V ■ Half-step, full-step and microstepping mode ■ Built-in protection diodes ■ Internal PWM current control ■ Low output saturation voltage ■ Designed for unstabilized motor supply voltage ■ Internal thermal shutdown Description The L6219 is a bipolar monolithic integrated circuits intended to control and drive both winding of a bipolar stepper motor or bidirectionally control two DC motors. The L6219 with a few external components form a complete control and drive circuit for LS-TTL or microprocessor controlled stepper motor system. The power stage is a dual full bridge capable of sustaining 46V and including four diodes for current recirculation.
