Overview
The LV8827LFQA-NH is a PWM-type driver IC designed for three-phase brushless DC motors. It supports rotational speed control via PWM pulse input. The device operates within a supply voltage range of 8 V to 35 V and delivers a maximum IGBT collector current of 1.5 A. It features a typical switching frequency of 62 kHz and dissipates up to 1.35 W of power. The component is housed in a 24-pin VQFN package measuring 4 mm x 4 mm with a height of 0.765 mm, suitable for surface mount installation.
Feature Summary
- PWM-type driver IC architecture optimized for three-phase brushless motor applications
- Supports rotational speed control through external PWM pulse input signals
- Integrated high-current output stage capable of driving IGBT loads
Applications
- Three-phase brushless DC motor drive systems
- Industrial motion control equipment requiring PWM speed regulation
- Automotive or appliance BLDC fan and pump controllers
Procurement Notes
Verify end-of-life status and last-time-buy dates directly with onsemi or authorized distributors. Confirm that the specific suffix matches required thermal and packaging specifications. Check moisture sensitivity levels and reflow soldering profiles before procurement. Ensure compatibility with existing PCB footprint and thermal management design constraints.
Selection Notes
Select this component when a dedicated pre-driver for three-phase BLDC motors is required. It is suitable for designs needing integrated PWM speed control logic. Consider the 1.5 A output capability and 35 V voltage rating against load requirements. Evaluate the VQFN-24 package size for space-constrained layouts.
Part Context
This part belongs to onsemi's family of motor drivers and controllers. It functions as a specialized interface between microcontroller logic and power stages. The device simplifies BLDC motor control by handling phase commutation and speed regulation inputs.
Replacement Considerations
LV8829LFQA-NH: Offers similar three-phase BLDC capabilities but differs in pin count (24 vs 32) and package dimensions. Verify functional equivalence and mechanical fit before substitution.
