Overview
The E-L6219 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 for LS-TTL or microprocessor-controlled systems. The power stage is a dual full bridge capable of sustaining 46 V, including four diodes for current recirculation. An internal pulse-width-modulation (PWM) controls the output current to 750 mA with peak startup current up to 1 A. Wide range of current control from 750 mA per bridge is permitted by means of two logic inputs and an external voltage reference.
Feature Summary
- Supports half-step, full-step, and microstepping modes
- Includes built-in protection diodes and cross conduction protection
- Features internal thermal shutdown to disable outputs if temperature exceeds safe limits
Applications
- Bipolar stepper motor control
- Bidirectional DC motor control
- LS-TTL controlled stepper motor systems
- Microprocessor controlled motor applications
Procurement Notes
Verify the specific suffix (e.g., DSA, DS013TR) against the required package type (SOIC-24) and operating temperature range. Confirm availability status as some variants may be discontinued. Ensure the selected part matches the system's voltage requirements of 10 V to 46 V and current needs up to 750 mA per winding.
Selection Notes
Select based on the required stepping mode support and interface compatibility with LS-TTL or microprocessors. Consider the wide voltage range suitability for unstabilized motor supplies. Evaluate the need for internal PWM current control and thermal protection features for robust operation in varying environmental conditions.
Part Context
The E-L6219 belongs to the L6219 series of stepper motor drivers from STMicroelectronics. It is a specialized IC intended for precise motor control applications requiring high reliability and integrated power stages. The component is part of ST's broader portfolio of motor control solutions.
Replacement Considerations
Check for direct pin-to-pin replacements within the L6219 family, such as L6219DSA or L6219DS013TR, ensuring identical electrical characteristics and package dimensions. Verify that any substitute maintains the same 46 V rating and 750 mA output capability.
