Overview
The onsemi LB11851FA-BH is a dedicated motor driver IC designed for controlling brushless DC (BLDC) motors. It operates within a supply voltage range of 6 V to 16 V and utilizes a 10-pin Micro package. The device integrates PWM control functionality, making it suitable for fan controller applications. Key electrical specifications include an operating supply current of 6.5 mA and a maximum collector-emitter voltage of 16 V. It supports industrial temperature grades with a minimum operating temperature of -40°C.
Feature Summary
- Integrated PWM control capability for precise motor speed regulation
- Designed specifically for brushless DC (BLDC) motor applications
- Compact surface-mount packaging for space-constrained designs
Applications
- Fan controller systems
- Brushless DC motor drive circuits
- Industrial automation equipment requiring low-voltage motor control
Procurement Notes
Verify the exact suffix 'BH' against the manufacturer's official datasheet to confirm pinout and thermal characteristics. Ensure the procurement source provides valid traceability documentation. Confirm that the component meets the required industrial temperature grade specifications for the intended deployment environment before finalizing orders.
Selection Notes
Select this component when designing BLDC motor drivers requiring a 6V-16V supply range. Consider the 10-pin Micro package constraints for PCB layout. Evaluate the 6.5 mA operating current against system power budgets. Verify compatibility with existing PWM control signals from the host microcontroller or logic circuitry.
Part Context
This part belongs to onsemi's motor driver portfolio, specifically targeting small-scale BLDC applications. It differs from general-purpose H-bridge drivers by its optimized architecture for fan and pump control. The device simplifies design by integrating necessary gate drive functions within a compact form factor.
Replacement Considerations
Cross-reference with other onsemi BLDC drivers in the same voltage class. Verify pin-to-pin compatibility if substituting with similar packages. Check functional equivalence regarding PWM input requirements and thermal performance under identical load conditions.
