LIN-Slave for relay and DC motor control
4.5 MLX81150 in 1- and 2- phase BLDC (brush less DC) Motor control applications
BLDC motors are used today in several permanent running automotive applications. 1- and 2-phase BLDC
motors are applied in several auxiliary applications as small pumps and blowers. In case these pumps
request a LIN or PWM interface connection, the MLX81150 is a perfect solution for that. The commutation
information for the brush less DC motors is provided by a hall switch/latch reacting on positive and negative
magnet field of the permanent magnet rotor.
