Description

  • TIDA-00919, Single-Layered, Refrigerator Fan Reference Design Enabling High Efficiency Drive. This reference design is a singled-layered, cost-effective, small-form-factor, three-phase sinusoidal motor drive for sensor BLDC fan motors specified up to a maximum current of 1A RMS at 18V 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 efficiency and overall performance, speed control via external pulse-width modulation (PWM) input which brings an ease of speed control
