L6219R013TR

Overview

The L6219R013TR 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 forms a complete control and drive circuit with minimal external components, compatible with LS-TTL or microprocessor systems. The power stage features a dual full bridge capable of sustaining 46 V, including four diodes for current recirculation. Internal PWM controls the output current to 500 mA per winding, with a peak startup current up to 1 A. The device supports half-step, full-step, and microstepping modes.

Feature Summary

• Integrated dual full-bridge power stage with built-in cross-conduction protection and recirculation diodes
• Internal pulse-width-modulation (PWM) current control with adjustable reference via logic inputs
• Thermal shutdown circuitry that disables outputs when safe operating temperature limits are exceeded

Applications

• Bipolar stepper motor control systems
• Bidirectional DC motor drives
• Microprocessor-controlled motion control applications

Procurement Notes

Verify the specific suffix 'R' against the manufacturer's official documentation, as it indicates a distinct electrical specification compared to other L6219 variants. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the 24-SOIC package dimensions match your PCB footprint design constraints before finalizing procurement.

Selection Notes

Select this component when a fully integrated driver with internal current limiting and thermal protection is required for bipolar stepper or DC motor applications. The 500 mA continuous output current rating suits low-to-medium power loads. Consider the parallel interface and logic input configuration for system compatibility. Verify voltage supply ranges align with the unstabilized motor supply design.

Part Context

This part belongs to the L6219 series of motor drivers from STMicroelectronics. The series provides complete solutions for controlling bipolar stepper motors and DC motors. The L6219R variant specifically offers a 500 mA output current capability, distinguishing it from higher-current versions like the L6219D which supports 750 mA. All variants share the same 24-SOIC package and core architectural features.

Replacement Considerations

The L6219DSA13TR and L6219DS013TR are alternative variants within the same family but feature different output current ratings (750 mA). Direct substitution requires verifying if the increased current capacity fits the application and if the specific 'R' suffix characteristics are critical. No other direct equivalent part numbers are confirmed in the provided data.
