Microstep Stepper motor driver circuit

Half-step, full-step and microstep Stepper motor driver

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.

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
