LV5219LG-MPB-E

LED Driver IC Overview

The LV5219LG-MPB-E is a monolithic integrated circuit designed for driving two-phase stepper motors, manufactured by Sanyo (now part of Semicon). It integrates a chopper driver with constant current control and includes built-in protection features such as overcurrent protection and thermal shutdown. The device operates within a supply voltage range of 8V to 36V and supports microstepping resolutions up to 1/16. It utilizes a fixed off-time PWM chopper scheme to maintain stable motor current, reducing power dissipation in the motor windings compared to linear drivers.

LED Driver IC Procurement Notes

Verify the manufacturer origin, as Sanyo Semiconductor assets were acquired by Onsemi. Ensure the specific suffix matches the requested package and tape/reel configuration. Confirm that the component meets current RoHS compliance standards required for your assembly process. Cross-reference the date code and lot marking to ensure authenticity from authorized distribution channels.

LED Driver IC Selection Notes

Select this component when a compact solution for bipolar stepper motor control is required without external discrete drivers. It is suitable for applications needing microstepping capabilities to reduce vibration and noise. Consider the operating voltage range and thermal requirements of the specific motor load. This IC is appropriate for space-constrained designs where integrating protection features reduces bill of materials complexity.

LED Driver IC Part Context

This component belongs to the LV52xx series of stepper motor driver ICs from Sanyo Semiconductor. These chips are widely used in consumer electronics and industrial machinery for reliable motion control. The series is known for its high integration level, combining logic, driver stages, and protection circuits into a single package, simplifying system design for manufacturers.

LED Driver IC Replacement Considerations

Direct replacements may include the LV5219P or other variants within the LV52xx family depending on the specific package type and pinout compatibility. Verify electrical parameters and thermal characteristics before substitution. Consult official cross-reference lists from the current manufacturer for approved equivalents.
