L6219DSTR-T Description

Short technical summary and product information.

The L6219DSTR-T from Allegro Microsystems is a dual full-bridge PWM motor driver IC. It is designed to drive bipolar stepper motors or two DC motors bidirectionally. The device supports continuous output currents up to 750 mA and can sustain output voltages of 45 V.

 

Key features include internal pulse-width modulation (PWM) for output current control, allowing users to select output current limits. The driver also incorporates internal clamp and flyback diodes for protection against inductive transients, and internal thermal shutdown circuitry to prevent overheating. Special power-up sequencing is not required.

 

This motor driver is supplied in a 24-pin surface-mountable SOIC package, making it suitable for compact designs. It is lead (Pb) free with 100% matte tin leadframe plating, indicating compliance with modern environmental standards.

 

The L6219DSTR-T is suitable for general-purpose applications requiring precise motor control, such as in robotics, automation, and other electromechanical systems.
