3-PHASE BLDC MOTOR CONTROLLER IC
FOR APPLICATION UP TO 40 W
The MLX80302 is a smart 3-phase motor controller with integrated power FETs. The device is opmized for driving
brushless DC motors with RMS current up to 1.8 A and start-up current up to 2.6 A.
Suited for automove and motorcycle pump applicaons up to 20 W on the 13 V baery voltage, the MLX80302 is also
a good t for a wide range of home appliances and industrial pump applicaons up to 40 W on a 24 V regulated supply.
Applicaon board (APP80302) and Evaluaon board (EVB80302) are available to speed up the development.

The hummingbird’s beang wings ap at extremely
high frequencies, typically around 50 mes per second.
This allows it to y at speeds exceeding 15 m/s, to y
backwards or to seemingly be suspended in the air
