Overview
The LV8824QA-2H is a three-phase brushless DC motor pre-driver manufactured by onsemi, designed for open-loop speed control using the Hall sensor method. It operates within a supply voltage range of 7 V to 33 V and delivers an output current of 50 mA per phase. The device functions across an extended temperature range from -40°C to +105°C and consumes a typical operating supply current of 6 mA. Packaged in a 32-VQFN (5x5 mm) surface-mount format with exposed pad, it supports PWM interface and parallel control signals. With a maximum power dissipation of 1.45 W and a peak output voltage of 5.4 V, this component serves as a dedicated pre-driver stage for BLDC applications.
Feature Summary
- Three-phase pre-driver architecture optimized for open-loop BLDC motor control
- Integrated Hall sensor input processing for commutation sequencing
- Supports PWM-based speed regulation and direction management
- Designed for robust operation in automotive and industrial environments
Applications
- Brushless DC motor control in automotive systems
- Industrial fan and pump drive applications
- Home appliance motor control units
Procurement Notes
Verify end-of-life status and last-time buy dates directly with onsemi or authorized distributors. Confirm RoHS compliance and halide-free specifications for your manufacturing requirements. Check moisture sensitivity level handling instructions prior to PCB assembly. Ensure replacement availability if production continuity is critical.
Selection Notes
Select this component when a dedicated three-phase pre-driver for open-loop BLDC control is required. It suits designs needing Hall sensor integration without complex closed-loop algorithms. Consider thermal performance given the 1.45 W dissipation limit in the VQFN package. Verify compatibility with system voltage ranges between 7 V and 33 V.
Part Context
The LV8824QA-2H belongs to onsemi's family of motor controllers and drivers, specifically targeting brushless DC motor applications. It complements other products like the LV8824QA-NH, differing primarily in packaging configuration rather than electrical function. This part falls under the broader category of PMIC and motion control solutions offered by the manufacturer.
Replacement Considerations
The LV8824QA-NH is a confirmed substitute part number with identical electrical characteristics but differs in reel versus tray packaging. No other public substitutes are documented.
