E-L6219DSA

Overview

The E-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 sustaining up to 46 V with four built-in recirculation diodes. The device includes internal PWM current control regulating output current to 750 mA per winding, with peak startup current reaching 1 A. It supports half-step, full-step, and microstepping modes. The IC operates within a supply voltage range of 10 V to 46 V and functions at junction temperatures from -40°C to 150°C.

Feature Summary

• Integrates a dual full-bridge power stage with cross-conduction protection and built-in recirculation diodes for robust motor driving.
• Features internal pulse-width modulation (PWM) current control allowing adjustable output current up to 750 mA per bridge.
• Includes thermal shutdown circuitry that disables outputs when the chip temperature exceeds safe operating limits.

Applications

• Driving bipolar stepper motors
• Bidirectional control of brushed DC motors
• LS-TTL or microprocessor-controlled stepper motor systems

Procurement Notes

Verify component authenticity through authorized STMicroelectronics distributors. Confirm package integrity upon receipt. Check datasheet revisions for any updates. Ensure storage conditions meet moisture sensitivity level requirements. Validate pin compatibility before integration into existing designs.

Selection Notes

Select this component for applications requiring integrated control and power stages for bipolar stepper motors. Consider the 750 mA continuous current rating and 46 V maximum voltage. Evaluate thermal management needs due to internal power dissipation. Verify logic input compatibility with LS-TTL levels. Assess system requirements against available stepping modes.

Part Context

The E-L6219DSA belongs to the L6219 family of motor drivers manufactured by STMicroelectronics. It serves as an enhanced or equivalent version of the standard L6219 series components. This family provides complete solutions for stepper motor control, integrating logic, driver, and power sections in a single package to minimize external component count.

Replacement Considerations

E-L6219DSA is listed as a parameter-equivalent replacement for the discontinued L6219DSA. TB6562AFG,8,EL is another documented substitute option.
