Overview
The E-L6219DS013TR 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 operates with a supply voltage range of 4.75V to 5.25V and supports load voltages from 10V to 46V. The device features an output current of 750mA per winding, housed in a 24-SOIC package. It supports half-step, full-step, and microstepping modes with internal PWM current control and thermal shutdown protection.
Feature Summary
- Integrates dual full-bridge power stage with built-in protection diodes for current recirculation
- Includes internal pulse-width-modulation (PWM) for precise output current regulation
- Provides cross-conduction protection to prevent simultaneous switching during direction changes
- Features internal thermal shutdown circuitry to disable outputs under excessive temperature conditions
Applications
- LS-TTL controlled stepper motor systems
- Microprocessor-controlled stepper motor applications
- Bidirectional DC motor control circuits
Procurement Notes
Verify the specific suffix 'DS013' against official STMicroelectronics documentation to confirm exact packaging and tape-and-reel specifications. Ensure compatibility with LS-TTL logic levels and verify that the 24-SOIC footprint matches the target PCB design. Confirm RoHS compliance status as indicated in the latest datasheet revision before finalizing procurement.
Selection Notes
Select this component when driving bipolar stepper motors requiring up to 750mA per winding within a 46V limit. It is suitable for designs needing integrated PWM current control and thermal protection without external discrete components. Consider the 24-SOIC package constraints and operating temperature range of -20°C to 150°C for environmental suitability.
Part Context
This part belongs to the L6219 series of bipolar motor driver ICs from STMicroelectronics. It serves as a complete control and drive solution for stepper motors, combining logic control interfaces with high-power output stages. The series is known for its ability to operate with unstabilized motor supply voltages and provide robust protection features in industrial automation contexts.
Replacement Considerations
L6219DSA13TR is a documented variant within the same family offering similar functionality but may differ in packaging or grade. Verify pinout compatibility and electrical parameters before substitution.
