LM628N-6/NOPB

Overview

The LM628N-6/NOPB is a precision motion controller manufactured by Texas Instruments, designed for controlling brushless DC (BLDC) and brushed DC servo motors. It operates within a supply voltage range of 4.5 V to 5.5 V and draws 110 mA of working power current. The device features an octal output configuration with specific electrical characteristics including 2.4 V output voltage and 1.6 mA output current per channel. It supports through-hole installation in a PDIP-28 package and functions reliably across a temperature range of -40°C to +85°C.

Feature Summary

Integrated precision control architecture for brushless DC and brushed DC servo motor applications
Octal output stage providing independent control signals for multi-phase or multi-load configurations
Robust operational stability across extended industrial temperature ranges

Applications

Brushless DC (BLDC) servo motor control systems
Brushed DC servo motor drive circuits
Precision motion control modules requiring multiple synchronized outputs

Procurement Notes

Verify component authenticity through authorized distributors as the part status is obsolete. Confirm package integrity and pin alignment against the PDIP-28 mechanical outline drawing prior to integration. Ensure supply voltage constraints between 4.5 V and 5.5 V are strictly maintained during operation to prevent functional degradation.

Selection Notes

Select this component when designing systems requiring integrated control for BLDC or brushed DC servos with multiple output channels. Consider the PDIP-28 through-hole package for prototyping or high-reliability manual assembly environments. Evaluate thermal management requirements given the 110 mA operating current and specified temperature limits.

Part Context

This device belongs to the LM628 series of precision motion controllers from Texas Instruments. It serves as a specialized interface between logic-level control signals and motor drive stages, simplifying the design of complex servo systems by integrating necessary control logic and output drivers into a single monolithic circuit.
