Overview
The E-L6219R013TR is a bipolar monolithic integrated circuit designed by STMicroelectronics to control and drive both windings of a bipolar stepper motor or to bidirectionally control two DC motors. This component is part of a complete control and drive circuit for LS-TTL or microprocessor-controlled stepper motor systems. With its dual full-bridge power stage capable of sustaining up to 10V, it includes four diodes for current recirculation and cross conduction protection to prevent simultaneous cross conduction during switching. The E-L6219R013TR also features internal pulse-width-modulation (PWM) for output current control and thermal protection to ensure safe operating conditions.
