Overview
The E-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 operates with a supply voltage range of 4.75V to 5.25V and supports load voltages from 4.5V to 10V. The device features an output current of 500mA per winding, housed in a 24-SOIC package. It includes internal PWM current control, thermal shutdown, and protection diodes for robust operation.
Feature Summary
- Integrates full control and power stages for bipolar stepper or DC motor applications
- Features internal pulse-width-modulation (PWM) for precise current regulation
- Includes built-in cross-conduction protection and thermal shutdown mechanisms
Applications
- Bipolar stepper motor control systems
- Bidirectional DC motor drives
- Microprocessor-controlled motion control circuits
Procurement Notes
Verify the specific suffix 'R' against official STMicroelectronics documentation to confirm the 4.5V-10V load voltage rating, as this differs from standard L6219 variants. Ensure compatibility with LS-TTL logic levels and confirm the 24-SOIC package dimensions match the design footprint before finalizing procurement.
Selection Notes
Select this component when a lower load voltage range (up to 10V) is required compared to the standard 46V L6219. It is suitable for low-voltage bipolar stepper or DC motor applications requiring integrated PWM control and thermal protection within a compact surface-mount package.
Part Context
This part belongs to the L6219 series of motor driver ICs from STMicroelectronics. It shares the core architecture of driving bipolar stepper motors but is specified for lower voltage applications. The 'E-' prefix indicates enhanced or specific manufacturing variations, while '013TR' denotes the tape and reel packaging format.
Replacement Considerations
L6219DSA13TR: Verify if the higher 46V load voltage rating is acceptable for the application. L6219R013TR: Confirm if this is the identical base part number with different suffixing conventions.
