MLX81150

 

 

The MLX81150 is a highly integrated motor controller for DC- and 1-/2-Phase BLDC motor control in 12V automotive applications.
It is a high integration concept by putting a 16-bit-Flash-Microcontroller, voltage regulator, complete LIN-protocol, LIN-transceiver, Relay- and Power-FET-Gate-Driver as well as several blocks for DC and BLDC motor operation in one single monolithic IC.
The MLX81150 comes with an interface for Hall sensor connection in order to enable position sensing. The IC addresses positioning actuators with DC motors as throttle valves or window lifters as well as permanent running motors in auxiliary water or oil pumps using DC or 1-phase / 2-phase BLDC motors.
