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