LV8761V-MPB-E

Overview

The LV8761V-MPB-E is a dual H-bridge motor driver IC manufactured by Sanyo (now part of ON Semiconductor). It integrates two independent H-bridge circuits capable of driving DC motors or stepper motors. The device supports continuous output currents up to 2.0A per channel with peak currents reaching higher limits, powered by a supply voltage range typically spanning from 4.5V to 36V. Key features include built-in protection mechanisms such as overcurrent protection, thermal shutdown, and under-voltage lockout. It utilizes a standard logic interface for direction and enable control, housed in a compact SSOP-B24 package designed for efficient heat dissipation in space-constrained applications.

Feature Summary

• Integrates dual independent H-bridge drivers for simultaneous control of two DC motors or one bipolar stepper motor
• Includes comprehensive protection circuitry featuring overcurrent detection, thermal shutdown, and under-voltage lockout
• Supports flexible control interfaces compatible with standard CMOS logic levels for easy integration
• Designed with low on-resistance power MOSFETs to minimize conduction losses and improve efficiency

Applications

• Home appliance motor control systems including washing machines and vacuum cleaners
• Office automation equipment such as printers and copiers requiring precise motor positioning
• Industrial automation modules utilizing small DC or stepper motors for actuation
• Robotics platforms needing compact dual-motor drive solutions

Procurement Notes

Verify the manufacturer source carefully as Sanyo Semiconductor assets were acquired by ON Semiconductor. Ensure the specific suffix MPB-E matches the required tape-and-reel packaging configuration if automated assembly is planned. Confirm pin compatibility with existing PCB layouts due to potential minor revisions in newer production batches. Request original datasheets to validate electrical characteristics against current design requirements.

Selection Notes

Select this component when dual-channel motor control is required within a single footprint. It is suitable for applications demanding moderate current levels around 2A continuous without external heatsinks in typical ambient conditions. Consider alternative parts if higher current capacity or different package styles are needed. Evaluate thermal performance based on actual load duty cycles and ambient temperature constraints before finalizing the design.

Part Context

This part belongs to the LV8761 series of dual H-bridge motor drivers. It represents a mature solution for general-purpose motor control tasks. The series is widely recognized in consumer electronics and industrial sectors for its reliability and ease of use. Variants may differ in packaging or specific electrical ratings, but the core functionality remains consistent across the family.

Replacement Considerations

Check for direct equivalents from ON Semiconductor which now holds the rights to the Sanyo semiconductor portfolio. Other manufacturers offer similar dual H-bridge ICs with comparable pinouts and electrical specifications. Verify functional compatibility regarding control logic and protection thresholds before substitution.
