LB1980JH-S-TLM-E

Overview

The LB1980JH-S-TLM-E is a three-phase brushless motor driver IC manufactured by Sanyo. Designed for surface mount applications, it utilizes a 28-HSOP-H package with exposed pads and heat tabs to facilitate thermal management. The device operates within a voltage range of 4.5V to 22V and provides three output channels capable of driving brushless DC motors. It is specifically engineered for precision control tasks, such as driving VCR capstan motors, ensuring stable performance in consumer electronic applications requiring reliable motor drive solutions.

Feature Summary

• Integrated three-phase bridge driver architecture optimized for brushless DC motor control
• Surface mount construction with thermal pad design for efficient heat dissipation
• Wide operating voltage range supporting low-voltage consumer electronics

Applications

• VCR capstan motor drivers
• Brushless DC (BLDC) motor control systems
• Consumer audio/video equipment motor drives

Procurement Notes

Verify the manufacturer origin, as Sanyo's semiconductor assets were acquired by ON Semiconductor (now onsemi). Ensure the part number suffix matches the specific package variant required. Confirm active status through authorized distributors, as legacy components may have limited availability or require substitution verification based on current production lines.

Selection Notes

Select this component when a dedicated three-phase driver for low-to-medium power BLDC motors is required. The HSOP-H package suits space-constrained PCB designs. Consider thermal requirements due to the exposed pad; ensure adequate copper area for heat sinking. Verify input voltage compatibility with the 4.5V-22V range before integration into the target circuit design.

Part Context

This part belongs to the LB1980 series of motor drivers from Sanyo Semicon Device. The series focuses on integrated solutions for three-phase brushless motors, commonly found in home entertainment devices. The LB1980 family simplifies motor control design by integrating gate drivers and protection features into a single compact package, reducing external component count.

Replacement Considerations

Check for direct pin-compatible substitutes within the same series or updated generations from ON Semiconductor. Verify electrical parameters match if sourcing from alternative manufacturers. No specific public substitute part numbers are confirmed in the provided data.
