Key Document


This reference design is a sensorless brushless DC (BLDC) motor sinusoidal drive using the DRV10987 motor driver. The PCB is designed to lower the temperature of the DRV10987. The design targets cases that can over heat the DRV10987 or cases that need a low-case temperature due to material such as waterproofing on the case of the DRV10987. The end equipments that require this could be dryer fans, drain pumps, or air purifiers.

  • Improved efficiency due to lower temperature operation 
  • Over temperature protection
  • Over current protection
  • Better heat dissipation allows for up to 60-W usage
