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.The power stage is a dual full bridge capable of sustaining 10 V and including four diodes for current recirculation.
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.
