The MLX81200 is a highly integrated 3 phase motor controller
for 12V BLDC or PMSM automotive applications.
Its TruSense and SineDrive technologies enable Sensorless BLDC motor
control in a wide range of demanding applications.
SINEDRIVE
allows optimizing the motor current shape for any BLDC motor, resulting
in optimal efficiency with minimum torque ripple and lowest audible
noise.
SineDrive also allows sensorless sinusoidal motor control minimizing
conducted and radiated missions.
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.
