Overview
The LV8968BBUWR2G is a multi-purpose BLDC pre-driver manufactured by onsemi, designed for automotive applications. It features six high-side and low-side drivers in an SPQFP-48 surface-mount package. The device operates with a supply voltage range of 8 V to 28 V and delivers an output current of 400 mA per channel. Key timing specifications include rise and fall times of 75 ns. It supports temperatures from -40°C to 125°C.
Feature Summary
- Six-channel gate driver architecture providing independent high-side and low-side control for brushless DC motor applications.
- Automotive-grade design compliant with AEC-Q100 standards for reliability in vehicle environments.
- Fast switching characteristics with 75 ns rise and fall times to support efficient motor control operations.
Applications
- Automotive Brushless DC (BLDC) motor pre-driving
- Multi-phase motor control systems
- Vehicle actuator drive circuits
Procurement Notes
Verify the specific ordering suffix UWR2G against the official onsemi datasheet to confirm package type and tape-and-reel quantity. Ensure the procurement source provides valid RoHS compliance documentation. Cross-reference the Mouser part number 863-LV8968BBUWR2G with manufacturer catalogs to validate authenticity and current production status before finalizing orders.
Selection Notes
Select this component when designing automotive BLDC motor drives requiring a dedicated pre-driver stage. The 400 mA output current suits driving external power MOSFETs or IGBTs. Consider the SPQFP-48 package for thermal management needs. Verify that the 8 V to 28 V operating range aligns with the target vehicle's electrical system specifications.
Part Context
This part belongs to the LV8968B series of motor controllers and drivers. It serves as the pre-driver stage for complex motor control algorithms. The evaluation board LV8968BBGEVB is available for testing the associated controller functions. This component integrates protection features typical of automotive-grade gate drivers.
Replacement Considerations
Consult the onsemi product selection guide for direct pin-to-pin replacements within the LV8968 family. Verify compatibility with existing PCB footprints and thermal requirements. Check for updated revisions or alternative packages if lead times are critical.
