Brushless click - MikroElektronika 3-Phase Full-Wave Brushless DC Motor Driver

Brushless click carries Toshiba's TB6575FNG IC for driving 3-phase full-wave Brushless DC motors — which are ideal for powering flying drones. The click is able to safely drive external motors with up to 32V/2A.

The board features three pairs of on-board screw terminals. VBAT is for connecting an external 7-32V DC power supply. The other two are for connecting an external motor.

Precision control

Brushless motors have a very long operating life and can be precisely controlled – the speed is adjusted by the amount of input voltage (higher voltage equals more speed).

The TB6575FNG IC controls the rotation speed by changing the PWM duty cycle.

MOSFET chips

Two types of MOSFET chips on board switch the output on and off. This controls the voltage levels applied to the motor which in turn determines the speed and rotation of the motor shaft.

Brushless click communicates with the target board MCU over the PWM pin, as well as INT, AN and RST pins. The board is designed to use a 5V power supply only. See the documentation page for more details.

Brushless click is theoretically capable of outputting higher currents, however, in such a case the MOSFET chips have to be cooled down with an external cooler.

Applications

Automotive industry, drones (because of the good power-to weight ratio of brushless motors), computers, medical equipment, HVAC systems, small home appliances, robotics, battery powered systems, small cooling fans in computers, toys, etc.

Motor position detection error

Position detection is synchronized with the PWM signal generated in the IC. When the IC is used in a high speed motor a position detection error relative to the PWM frequency may occur. The detection is performed on the falling edge of the PWM signal. An error is recognized when the pin voltage exceeds the reference voltage.
