(includes all related assets)
The MLX81200 is a highly integrated 3 phase motor controller for 12V BLDC or PMSM automotive applications.
Its TruSense Technology enables sensorless BLDC motor control in a wide range of demanding applications.
TRUSENSE
combines RELUCTANCE/INDUCTANCE measurement with BEMF sensing for robust and reliable detection and tracking of the rotor position in harsh environments under heavily changing load conditions.
This also allows a very fast motor start-up as well as operation at very low speeds.
TARGET SENSORLESS BLDC APPLICATIONS- Pumps:
- Fuel pump
- Water pump
- Transmission Oil pump
- ABS oil pump
- Fans/Blowers:
- Engine cooling fan
- HVAC blower
- Other:
- Active suspension control
