LM629N-8/NOPB

Overview

The LM629N-8/NOPB is a precision motion controller manufactured by Texas Instruments, designed for brushless DC motor applications. It operates within a supply voltage range of 4.5 V to 5.5 V and draws a typical operating current of 110 mA. The device supports through-hole mounting in a PDIP-28 package and functions reliably across an industrial temperature range from -40°C to +85°C.

Feature Summary

Integrated precision control architecture for brushless DC motors
Supports commutation logic without external microcontrollers
Operates on standard single-supply voltage rails

Applications

Brushless DC motor drive systems
Precision motion control circuits
Industrial automation actuators

Procurement Notes

Verify component authenticity via manufacturer channels due to end-of-life status. Confirm RoHS compliance documentation matches the specific revision. Validate pinout compatibility with existing PCB footprints before integration. Review official datasheets for any recent process change notifications affecting performance specifications.

Selection Notes

Select this component when designing dedicated hardware solutions for BLDC motors requiring integrated commutation. Ensure the application environment stays within the specified -40°C to +85°C thermal limits. Verify that the required supply voltage aligns with the 4.5 V to 5.5 V operational window for stable performance.

Part Context

This part belongs to the LM628/LM629 family of precision motion controllers. While functionally similar to the LM628, the LM629 variant offers distinct pin configurations and internal optimizations tailored for specific brushless DC motor topologies. Both devices share the same core control philosophy but differ in physical interface requirements.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the end-of-life status, direct replacements may require redesigning the motor driver stage or adapting the PCB layout for alternative packages.
