LB11923V-MPB-E

Overview

The LB11923V-MPB-E is a three-phase brushless DC motor driver manufactured by onsemi. It operates within a supply voltage range of 4.4V to 7V and supports bipolar PWM interfaces for precise control. The device integrates pre-drivers configured as half-bridges to manage motor commutation and direction. Designed for surface-mount installation, it utilizes a 44-LSSOP package with a width of 5.60mm. The component functions reliably across an operating temperature range of -20°C to 80°C ambient temperature.

Feature Summary

Integrated three-phase brushless DC motor driver architecture
Supports bipolar PWM interface for commutation and direction management
Includes internal pre-driver half-bridge output configuration

Applications

Cooling fan motor drivers
Three-phase brushless DC motor control systems
General purpose motor driver applications

Procurement Notes

Verify the specific suffix MPB-E against current manufacturer documentation to confirm package type and availability status. Cross-reference the DigiKey part number 869-1224-2-ND for accurate identification. Confirm RoHS compliance and moisture sensitivity level requirements prior to integration into production workflows.

Selection Notes

Select this component for low-voltage three-phase BLDC applications requiring integrated pre-drivers. Ensure the system voltage remains within the 4.4V to 7V operational window. Verify that the 44-LSSOP footprint aligns with PCB layout constraints and thermal management strategies for the target environment.
