Why Melexis?



  • Well suited for 3-phase BLDC motor commutation
    • Hand-held power tools
    • E-bikes
    • Server fan
    • Vacuum cleaner
    • Flow meter
    • ...

The benefits

  • Robust component
    • ESD withstand up to 8 kV HBM
    • EMC performances
    • Reverse supply voltage protection
    • Under voltage detection
  • Low power with typical operating current of 2.1mA
  • Low voltage / Wide range options
    • 2.5-5.5 V (MLX92214)
    • 2.7-24V (MLX92215)

Low voltage allows to directly supply the IC from the MCU (no LDO needed)
Low Voltage & wide range help extend the runtime of the battery (e.g. Li-ion cells)

  • High sensitivity eases the magnet selection. It allows the use of cheaper magnets or relieves constraints on the air gap
  • Predefined settings available
  • Package options (TSOT, UTQFN and UA)

Why BLDC motor instead of DC

Why BLDC motor instead of DC?

BLDC motors are more efficient and also save weight (compared to DC).

What is 3-phase BLDC motor communication?

What is 3-phase BLDC motor communication?

In order to have a 3-phase BrushLess DC (BLDC) motor in motion, it is required to supply the appropriate windings sequentially. Commutation is the process of switching between the phases.
