LB1936V-MPB-E

Overview

The LB1936V-MPB-E is a dual-channel DC motor driver manufactured by onsemi, designed for precise control of small motors in consumer electronics. It integrates two H-bridge drivers capable of delivering continuous current to drive brushed DC motors or solenoids. The device features built-in protection mechanisms including over-current shutdown and thermal shutdown to ensure reliable operation under varying load conditions. It operates with a wide supply voltage range, making it suitable for battery-powered applications. The component is housed in a compact package to facilitate space-constrained designs.

Feature Summary

• Dual-channel H-bridge configuration for independent motor control
• Integrated over-current and thermal protection circuits
• Wide operating supply voltage range for flexible power design
• Compact surface-mount packaging for efficient board layout

Applications

• Portable electronic devices requiring small motor actuation
• Consumer appliances with fan or pump control
• Automotive interior modules such as seat adjusters or window lifts
• Industrial automation components using low-power actuators

Procurement Notes

Verify the specific suffix 'MPB-E' against the official datasheet to confirm pinout and packaging details. Ensure compatibility with the target system's voltage levels and current requirements. Check for RoHS compliance documentation if required by regulatory standards. Confirm availability through authorized distributors only to avoid counterfeit parts.

Selection Notes

Select this component when dual-motor control is needed in a single package. Consider its current rating relative to the motor's stall current. Evaluate the thermal performance based on the expected duty cycle and ambient temperature. Compare alternative drivers if higher current capacity or additional features like PWM frequency adjustment are required.

Part Context

This part belongs to onsemi's portfolio of motor control solutions, targeting cost-sensitive and space-efficient applications. It complements other discrete and integrated motor drivers by offering a balanced solution for low-to-medium power requirements. The product line emphasizes reliability and ease of integration for mass-produced consumer goods.

Replacement Considerations

Check for direct pin-compatible alternatives from onsemi or other manufacturers if supply constraints exist. Verify that any substitute matches the electrical characteristics and protection features. Ensure the replacement supports the same control interface and voltage range.
