LM628N-8

Overview

The LM628N-8/NOPB is a precision motion controller manufactured by Texas Instruments, designed for motor and ignition control applications. It operates within a supply voltage range of 4.5 V to 5.5 V and draws a typical operating supply current of 110 mA. The device supports an extended industrial temperature range from -40°C to +85°C. It is housed in a 28-pin PDIP package suitable for through-hole mounting.

Feature Summary

• Precision motion control functionality integrated into a single monolithic component
• Capable of driving motors and managing ignition systems with high accuracy
• Designed for robust operation across wide industrial temperature extremes

Applications

• Motor control systems requiring precise positioning
• Ignition system controllers
• Motion control circuits in industrial automation

Procurement Notes

This component is officially listed as End-of-Life (EOL) by the manufacturer. Availability is restricted, and it may not be sold in all regions. Verify current lifecycle status and sourcing options carefully before design finalization.

Selection Notes

Select this part only if legacy compatibility or specific precision motion control requirements are necessary. Consider that the device is discontinued; evaluate alternative modern solutions for new designs to ensure long-term supply stability.

Part Context

The LM628 belongs to the LM628 series of precision motion controllers. It is distinct from audio amplifiers like the LM380 or operational amplifiers like the LM358 found in general catalogs. Its primary function is dedicated motion and ignition management rather than signal amplification.

Replacement Considerations

Public confirmed substitute part numbers are not available in the provided documentation due to the End-of-Life status.
