The MLX90285LVK-ABA-000-SP is an important type of PMIC (Power Management Integrated Circuit) motor driver, controller and position sensor. It is a system-on-chip solution for controlling brushless DC (BLDC) motors. It offers a complete And high-performance position sensing and motor control solution. The device features an advanced MotionEngineTM and position sensor, along with powerful peripherals and I/Os, which allow high integration and easy customization of user applications.

The MLX90285LVK-ABA-000-SP is designed with integrated 3-channel Brushless DC (BLDC) three-phase driver with integrated transceiver and proportional current regulator and integrated low power hall sensors and digital signal processor (DSP) to enable an "auto-adapting" torque control to offer optimum performance. The device integrates sensing logic and brushless DC motor control in one single IC.

The application field of the MLX90285LVK-ABA-000-SP includes consumer electronics such as gaming, personal computers, Kettles, blenders, and hairdryers, consumer appliances, home automation, and industrial applications such as home appliances, and sewing machines.

This device works by controlling the speed and position of BLDC motors. It also provides advanced features such as closed loop speed, torque and current control, energy savings, and reverse BI-directional control of motor rotation. The device contains embedded mixed signal processor, analog and digital I/O which enables easier implementation of the position and speed algorithm along with the motor control system. In addition, it includes on-chip Hall elements for providing speed and position feedback.

It utilizes a Block Commutation process which switches power periodically to the phases to drive the motor through the feedback of "Hall elements". The application processor then receives input from the USB port to provide monitoring and control of the BLDC motor. The microcontroller receives, processes, and transfers the data via I2C port. The brushless DC motor driver requires a dedicated circuitry to provide the required drive signal waves with the right voltage, current and frequency. For this, the MLX90285LVK-ABA-000-SP has pre-defined output shapes (Sin, Cos...) with properly chosen voltage level and phase set as required by the motor.

To ensure that an optimal output signal is generated for the motor, the output wave shape should be generated at the speed or torque reference. The MLX90285LVK-ABA-000-SP is capable of providing a very accurate output signal for the motor, which results in a smooth and efficient operation of the motor. The device also has a built-in auto-calibration feature which ensures that the output signal is generated according to the desired motor requirements.
