LB1668M-MPB-H

Overview

The LB1668M-MPB-H is a bipolar logic motor driver manufactured by onsemi, designed for DC and general-purpose motor applications. It features two half-bridge outputs with a maximum output current of 1.5 A. The device operates within a supply voltage range of 6.4 V to 7 V and supports load voltages of 12 V or 24 V. It functions reliably across an operating temperature range of -30°C to +80°C. The component is housed in a 14-MFPS surface-mount package.

Feature Summary

• Integrates dual half-bridge output configuration for driving bipolar motors
• Utilizes standard logic interface for control signal compatibility
• Designed for robust operation in industrial and automotive environments

Applications

• DC motor control systems
• General-purpose motor driving circuits
• Industrial automation equipment

Procurement Notes

This component has reached End-of-Life status as of February 5, 2016. Availability is restricted, and it is no longer in active production. Buyers must verify current stock levels with authorized distributors or consider alternative replacement parts immediately. Compliance documentation such as RoHS and PCN notices should be reviewed prior to any final design commitment.

Selection Notes

Engineers selecting this part must account for its discontinued status and limited availability. The specific 6.4 V to 7 V supply voltage requirement limits flexibility compared to wider-range drivers. Designers should evaluate the 1.5 A output capability against their load requirements and ensure the 14-MFPS package fits the PCB layout constraints before proceeding with procurement or design integration.

Part Context

The LB1668M belongs to the broader family of motor controllers and drivers from onsemi. This specific variant is optimized for low-voltage bipolar motor applications. It falls under the PMIC category, specifically within motor driver subcategories. The component represents legacy technology suitable for existing designs rather than new development projects requiring long-term supply assurance.

Replacement Considerations

Due to the EOL notification dated February 5, 2016, direct substitutes are not explicitly listed in the provided documentation. Users should consult onsemi's official cross-reference tools or contact sales representatives for qualified replacement recommendations that match the 14-MFPS package and 1.5 A output specifications.
