STMicroelectronics, Inc. PMIC - PMIC - Motor Drivers, Controllers - E-L6219DSATR E-L6219DSATR

The E-L6219DSATR is a bipolar stepper motor driver designed to control both windings of a bipolar stepper motor or bidirectionally drive two DC motors. It supports output currents up to 750 mA per winding, with a peak startup current of 1 A, and operates within a voltage range of 10 V to 46 V. The device features half-step, full-step, and microstepping modes, allowing for flexible motor control. This integrated circuit includes built-in protection diodes and internal PWM current control, ensuring efficient operation with low output saturation voltage. It is designed for use with unstabilized motor supply voltages and incorporates thermal shutdown protection to prevent overheating. The E-L6219DSATR is packaged in a SO24 format and is suitable for applications requiring precise motor control with minimal external components.
