The L6219DSA is a bipolar stepper motor driver designed for the automotive range. It is capable of driving both windings of a bipolar stepper motor, with an output current of up to 750mA each winding. The voltage range is wide, from 10V to 46V. It supports half-step, full-step, and microstepping modes, and includes built-in protection diodes, internal PWM current control, and low output saturation voltage. The L6219DSA can also be used to bidirectionally control two DC motors.
The L6219DSA is a bipolar monolithic integrated circuit designed to control and drive both windings of a bipolar stepper motor or bidirectionally control two DC motors. It features a dual full-bridge power stage capable of sustaining 46V and includes built-in protection diodes for current recirculation and cross-conduction protection.
