LB1980H-MPB-E

Overview

The LB1980H-MPB-E is a monolithic digital integrated circuit designed as a low-saturation bidirectional motor driver for low-voltage applications. Manufactured by Sanyo (now ON Semiconductor), this component utilizes a compact SSOP-14 package to facilitate space-constrained designs. It integrates control logic and power output stages on a single chip, enabling efficient driving of DC motors in both forward and reverse directions without requiring external discrete components for basic operation.

Feature Summary

• Monolithic integration of control logic and power output stages
• Low saturation voltage design for improved efficiency
• Bidirectional drive capability for DC motors
• Compact SSOP-14 package for space-saving PCB layouts

Applications

• Domestic appliances with DC motor control
• Office automation equipment
• Industrial control systems
• Automotive accessories

Procurement Notes

Verify the manufacturer designation carefully, as Sanyo's semiconductor division was acquired by ON Semiconductor. Ensure the ordering suffix matches the required tape-and-reel or tube packaging configuration. Confirm that the specific variant aligns with current production status and lead times from authorized distributors.

Selection Notes

Select this component when a compact, low-voltage solution for bidirectional DC motor control is required. The low-saturation characteristic makes it suitable for battery-operated devices where efficiency is critical. Consider the thermal performance within the SSOP-14 package relative to the expected load current and ambient temperature conditions.

Part Context

This part belongs to the LB1980 series of motor drivers, which are widely used in consumer electronics and industrial applications. The series is known for its reliability and ease of use in driving small to medium-sized DC motors. The MPB-E suffix typically indicates a specific packaging or environmental compliance variant offered by the manufacturer.

Replacement Considerations

Direct replacements may include other parts from the LB1980 family or compatible bidirectional motor drivers from ON Semiconductor. Verify pin compatibility and electrical specifications before substitution.
