Overview
The LV8829LFQA-NH is a three-phase BLDC motor pre-driver by onsemi, designed for open-loop speed control using Hall sensor inputs. It operates within a supply voltage range of 8 V to 35 V and supports a maximum collector current of 1.5 A. The device utilizes Bi-CMOS technology and features a 24-pin VQFN package measuring 4 mm x 4 mm with a height of 0.765 mm. It functions at a typical switching frequency of 62 kHz and operates reliably across a temperature range of -40 °C to +80 °C.
Feature Summary
- Provides three-phase half-bridge pre-driver outputs for brushless DC motors
- Supports open-loop speed control via Hall sensor input method
- Integrates PWM parallel interface for efficient signal processing
Applications
- Open-loop speed control systems for BLDC fans
- Small household appliance motor drives
- Industrial cooling system controllers
Procurement Notes
Verify the specific suffix 'NH' against official datasheets to confirm lead-free compliance and RoHS status. Ensure the operating voltage requirements align with the 8 V to 35 V specification. Confirm that the thermal performance meets the +80 °C junction temperature limit for the intended application environment.
Selection Notes
Select this component when designing open-loop BLDC applications requiring a compact 24-pin VQFN footprint. It is suitable for systems needing up to 1.5 A output current with a 35 V supply capability. Consider the -40 °C to +80 °C operating range for environmental constraints.
Part Context
This part belongs to the LV8829 series of motor drivers from onsemi. It is distinct from similar models like the LV8824QA-NH, which offers different pin counts and current ratings. The LV8829LFQA-NH specifically targets cost-sensitive, space-constrained BLDC applications.
Replacement Considerations
Check for direct substitutes in the LV882x family. Verify pin compatibility and electrical specifications before replacing with other onsemi pre-drivers.
