Single-Layered: Refrigerator Fan Reference Design Enabling High Efficiency Drive
Description
This reference design is a singled-layered: cost-effective: small-form-factor: three-phase sinusoidal motor drive for sensored BLDC fan motors specified up to a maximum current of 1 A RMS at 18 V maximum. The unique: single-sided design helps to bring down the system cost. The on-board Hall sensors facilitate the board mounting inside the motor itself. The design also demonstrates the features of DRV10970 such as single hall operation for further cost optimization: sinusoidal drive with adaptive drive angle adjustment for better system efficinecy and overall performance: speed control via external pulse-width modulation (PWM) input which brings an ease of speed control: etc.
Features
- Minimized BOM components and overall cost by single layered designHighly integrated system with protection features like motor lock detect: short circuitSpeed command for controlling fan speed using external PWMComplete solution for spinning refrigerator fanDesign demonstrates DRV10970 device features: like adaptive drive angle adjustment: sensored: sinusoidal drive for better acoustics: efficiency and performanceSmall form factor design with on-board Hall sensors with support for one- or 3-Hall operation
