How Does The Brushless 24 Click Board™ Work?
The Brushless 24 Click Board™ is based on the DRV10866, a fully integrated three-phase BLDC motor driver from Texas Instruments. The DRV10866 motor driver comes with integrated power MOSFETs with current drive capability up to 800mA peak (based on populated 3.9k resistor), specifically designed for low-noise energy-saving fan motor drive applications connected to the terminals labelled as U, V, W, and COM. It provides PWM/enable control interface (PWM pin of the mikroBUS™ socket), wide operating voltage range, robust on-chip protection features, low RDSON, and efficient switching algorithms to ensure excellent thermal performance and high drive capability.
The DRV10866 implements a 150° commutation (sensorless BEMF control scheme) for a 3-phase motor alongside a synchronous rectification mode of operation that achieves increased efficiency for motor driver applications. In addition, the DRV10866 has a frequency generator pin (FG) that outputs a 50% duty cycle of PWM waveform in the normal operation condition. The FG represents the motor speed and phase information, detectable through an interrupt pin of the mikroBUS™ socket and a blue LED indicator marked as FG. During the Start-Up sequence, the FG output will stay at high impedance until the motor speed reaches a certain level and BEMF is detected, while during lock protection conditions, the FG will remain high until the motor restarts and the Start-Up process is completed.
Apart from this function, the DRV10866 can also output either full FG or half of the FG to indicate motor status with open-drain output through the FGS SEL selection jumper. When FGS SEL is placed in a VCC position, the FG output frequency is half that when the jumper is set to a GND position. The DRV10866 has multiple built-in protection blocks, including UVLO, overcurrent protection, lock protection, and thermal shutdown protection.
The Brushless 24 Click Board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. This way, it is allowed for both 3.3V and 5V capable MCUs to use the communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
