LB1938FA-BH

Overview

The onsemi LB1938FA-BH is a single-channel brushed DC motor driver IC designed for forward and reverse operation. It operates within a supply voltage range of 2.2V to 10V and supports output currents up to 0.8A. The device integrates control logic and power stages in an 8-pin MSOP package, featuring low saturation voltage for efficient performance. It complies with RoHS standards and functions reliably across temperatures from -30°C to +85°C.

Feature Summary

Integrates fully integrated control and power stage for single-channel brushed DC motor driving
Supports bidirectional operation with low-saturation forward and reverse drive capabilities
Operates with wide supply voltage range suitable for various low-voltage applications

Applications

Brushed DC motor control in consumer electronics
Fan speed regulation systems
Small appliance motor drivers

Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix BH matches project requirements. Check current availability status as this part may be subject to obsolescence notices. Ensure proper handling for moisture-sensitive devices during storage and assembly processes.

Selection Notes

Select this component for applications requiring a compact, single-channel solution for brushed motors. Consider the 8-pin MSOP package for space-constrained designs. Evaluate thermal management needs based on the 400mW power dissipation rating. Verify compatibility with system voltage levels between 2.2V and 10V before integration.

Part Context

This component belongs to the general-purpose driver category from onsemi. It is distinct from other series like FDB38N30U MOSFETs or LB1930MC controllers. The LB1938FA-BH specifically targets low-power brushed motor applications with integrated control features.

Replacement Considerations

Public records indicate this part is obsolete. No verified substitute part numbers are provided in the source data. Consult manufacturer documentation for potential end-of-life alternatives.
