Stepper motor driver
Features
■ Able to drive both windings of bipolar stepper motor
■ Output current up to 500 mA each winding ■ Wide voltage range 4.5 V to 10 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 L6219R 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 L6219R with a few external components form a complete control and drive circuit for LS-TTL or microprocessor controlled stepper motor system.
