LM628N-8/NOPB

Overview

The LM628N-8/NOPB is a precision motor controller manufactured by Texas Instruments, designed for applications requiring accurate motion control. 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. This component belongs to the LM628 series and functions as a dedicated solution for fan, motor, and ignition control systems.

Feature Summary

Provides precise control capabilities for motor and motion applications
Operates with low power consumption at 110 mA supply current
Supports wide industrial temperature operation from -40°C to +85°C

Applications

Precision motor control systems
Fan speed regulation
Ignition controllers

Procurement Notes

Verify end-of-life status before design finalization, as this specific part number is listed as obsolete or discontinued by the manufacturer. Confirm availability through authorized distributors or secondary markets if immediate procurement is required. Ensure that the PDIP-28 through-hole package remains compatible with existing PCB footprints and assembly processes. Validate RoHS compliance documentation for regulatory adherence in target markets.

Selection Notes

Select this component when a dedicated precision motor controller is required rather than a general-purpose microcontroller. The fixed 5V supply requirement limits use cases to stable 5V logic domains. Consider the PDIP-28 package size constraints against available board space. Evaluate whether the integrated driver capabilities meet load requirements without external amplification.

Part Context

This part belongs to the LM628 family of precision motor controllers from Texas Instruments. It is distinct from operational amplifiers like the LM358 or switching regulators like the LM5008 found in similar catalogs. The LM628 series focuses specifically on motion control algorithms and drive signals, differentiating it from general PMIC or signal conditioning ICs.
