LV8961HUWR2G

Overview

The LV8961HUWR2G is an automotive-grade, three-phase BLDC pre-driver manufactured by onsemi. It features a 400mA output current capability and operates with supply voltages ranging from 5.5V to 28V. The device supports load voltages between 4.5V and 40V, utilizing NMOS technology within a 48-SQFP (7x7) package. Designed for fan controller applications, it integrates SPI interface control and functions as a half-bridge driver. The component is qualified for operation across a temperature range of -40°C to 150°C TJ.

Feature Summary

Automotive-grade reliability compliant with AEC-Q100 standards
Integrated SPI interface for digital control and configuration
Three-phase half-bridge pre-driver architecture for BLDC motors

Applications

Fan controllers in automotive systems
BLDC motor drive applications
Multi-phase motor control circuits

Procurement Notes

Verify the specific ordering suffix to ensure correct packaging and tape/reel specifications. Confirm RoHS3 compliance status and REACH restrictions prior to integration. Check for any recent Product Change Notifications (PCN) regarding bonding wire or manufacturing site changes. Ensure the design accounts for the specified MSL rating and thermal dissipation requirements for the SQFP package.

Selection Notes

Select this component when designing automotive fan control systems requiring a dedicated pre-driver for three-phase BLDC motors. The integrated SPI interface simplifies system architecture by reducing external logic components. Consider the 400mA output current and wide voltage operating range when sizing power stages. Verify that the 48-pin SQFP footprint aligns with the PCB layout constraints and thermal management strategy.

Part Context

This part belongs to the LV8961 series of motor drivers designed for automotive environments. It serves as a specialized pre-driver stage, distinct from full bridge drivers or standalone gate drivers. The series targets high-reliability applications where robust control of brushless DC motors is essential for cooling and ventilation systems.
